151MPH in the MSP

[daedalus]

oh yea. its possible. It was pulling really hard still. With gearing changes i really think 180mph would be possible with allmost no work.

Greddy Turbo Timer had a peak speed of 243 km/hr which is 151mph. I wasnt sure how much the speedo would be off, because it was really far past 140. That was sitting at about 6500rpms.

I'm still shaking from the run. (boom07)

Car felt really good at that speed, and it climbed suprisingly quickly.

[brokemp3]

wow you must have had a really long track...................
(notcool)

[MP3Architect]

damn you for going faster than me!!!!! so how did you overcome the ecu stopping you? what rpm were you at?

[daedalus]

That was sitting at about 6500rpms.

Microtech standalone = no more govenor.

and i did this on about the closest thing to a damn track there is around here. Not another car was seen the entire night, specifically during the run. The only person at danger was myself. I'm not wreckless, careless or stupid thank you very much. Its much more dangerous for some asshat to be weaving through traffic at 80 mph than it is for me to do 150 on a deserted straight road.

but lets not get into that argument. I wanted to start a discussion of top speed possibilities in the speed, because i dont know of too many people that have actually gone this fast, and what their views on increasing top speed were.

[AbsoluteSwed]

i dont believe it until i see some proof in the form of video

[MyOrangeToy]

I did over 220km/h once on the highway.... wasn't hard to get there at all I only have catback+boostcontroller back then

[MP3Architect]

i dont know of too many people that have actually gone this fast
i know pirana has been up in those numbers in his nsx. perhaps even higher.

[brealmp3]

that is nice. i don't think there is anything wrong with testing the limits of a car if your in a clear area where you put only yourself at risk. and i don't think he would lie about reaching this speed, because what would he get out of lying about it.

[FSDET]

i dont think 180mph is possible with the speed .. i dont know why but i dont think so hehe

[daedalus]

i dont believe it until i see some proof in the form of video


Maybe this weekend. I need to find someway to rig up the camera to record though. I wouldnt feel safe driving that fast with one hand on the wheel... that would be asking for death.

[daedalus]

i know pirana has been up in those numbers in his nsx. perhaps even higher.


And i just meant in their MSP's... i know lots of people have actually driven a car faster than this. Just in the MSP its pretty damn hard with the govenor on there.

[DE31]

do like how someone else did they put it on the steering wheel and strapped it there somehow. asian6er did that i think. at least thats how i remember his name.

Warning! Threadjack!

Went 181 mph in my "other" hot rod about 10 years ago. 1979 10th Anniversary Trans Am. At that time had a 12.4 to 1 race gas 467 c.i. beast motor. Original 4-speed car, 3.23 rear end and ran it up to 7200 rpm. My mph calculation didn't account for tire growth, which surely occurred. My evidence is that my windows were down and it sucked the headliner out of the car. Damn thing still has no headliner. Would have rolled them up, but had these blinking blue light things in the rear view...at least temporarily. That's what you get for having a 600 hp T/A in the driveway and Smokey and the Bandit is on the late movie, lol.

FWIW, I welded 7 of 8 rod bearings to the crank, and turned it blue/purple. The block split right through the mains. Turns out motors with 4.21" stroke don't like 7200 rpm without mods I didn't have. Yes, I got away. Coasted the last mile or so and still cooked the rotors turning onto my road.

Now it has a safe 9.25 to 1 462 c.i. pump gas motor (built by me...with a rev limiter...TYVM), and it still lays two stripes when I hit 4th at 80-90 mph. I love my MSP, but there's something special about a ride that sets off every car alarm within 2 blocks...with mufflers. Every bike short of a 'busa is afraid to try me. Funny thing is, it's only about a 12.5-13.0 car because of traction. A properly built MSP can do that. The bikes don't know that though!

What I'm getting at here is that I've been 180+. I don't want to do it again in a street car on the street, and I sure as hell don't want to do it in my MSP. If someone else does, I pray they're on the track with the proper safety equipment. Be careful guys. I got lucky trying to break the sound barrier. You might not.

[BradC]

(thumb) hell yeah.

How hard was she pulling at 150?

[Newf]

I have my doubts about the aerodynamics of the car allowing 180mph. I had my mp3 up to just over 130, but it was a long long LONG road. I've never really pushed my speed past 110 before. Not sure why, but I just never. 150 seems a "bit" much but then again I've hit 145 in my old 97'lude and it was still going so who knows...maybe

[vxfilmer1000]

I see it happening.... i would still like to see some video of it tho it would make me proud (thumb)

[MoJoeTCM]

180 would not be possible unless you re-geared your transmission.....unless you had over 300 hp there is no purpose for even doing that anyway.....My car can hit about 138-140 before it shuts off. I found that out going down a hill and i was no where near 6500....so I am not doubting he did it...but why even come up with the though of going 180 in our cars....that would be plain stupid, even if you had that much hp on a rebuilt motor you wouldnt be able to keep up with cars that could go that fast stock.....

[jeffmsp]

i can get up to the speed govenor pretty quick and the car is definately still pulling so with the microtech and a few other mods i see it feasable. What kind of tires are you trusting at those speeds? Im pretty sure the stockers arent meant for that kind of speed. (180mph)

[dirtysouth_msp]

Not sure why most of you have such a hard time believing that daedalus hit 151MPH. The car is governed close to 140 (stock) and he does not have a governer. I've hit the governer several times with more RPMs to play with. I'm not saying that it is not scary, but I believe that 151 is totally possible with his setup. Don't hate cause his shit is faster than yours!

[kipper88]

Congrats man...personally i don't have the balls to go that fast. I lost control at highspeeds in a monte carlo about 4 years ago and now I am a pussy. Its ok though I didn't buy the msp to break the sound barrier.

Oh the gearing would have to be re-done, but i want every gear to be longer anyway, so that really wouldnt be a problem. If anything else, i could cruise on the highway at 2300rpms instead of 3500rpms.

As for the tires, i was on the stockers last night, and they are ZR rated so good for at least 149mph, but RE050's which are the newer version are ZR87W's which are limited at 168mph. So tires would become a very real concern.

As for the 180, areodynamically i dont see that being a problem, as long as you had enough hp to back you up. Last night the car was pulling really hard up top at 150 and thats with 250hp/293tq so with a higher boost setting, or some more mods (giggle), and the new gearset i think 180 could be very feasable.

One last thought was that a tranny cooler would be a must, after seeing TurfBurns templogs from his higer speed runs, the tranny oil must be getting uber hot, so for a 180run, it would be a neccessity. Also, my brakes were stinking more than a 50 cent whore last night after slowing down, and i really think that without an upgraded BBK it really wouldnt be wise to attempt such a run.

One thing i forgot to mention was that when i hit 150 allmost on cue last night my drivers side door started howling horrendously. Like it lost seal at that speed. I dont know what was going on but i figured that was a good cue to shut her down.

All in all, to be honest, it is my new goal to make a 180mph capable MSP. All the mods required are mods that i was going to do anyway (tranny gearing, tranny cooler, BBK, new tires/wheels) so the end result is going to be a high speed MSP one way or the other. To be honest, i dont see myself ever attempting to make a 180mph run (unless i was like in the desert or something) because i really think i lack the balls to do that. Last night got the adrenaline pumping awful fast.

I wasnt aware our valvetrain was that shitty?

[Brian MP5T]

I wasnt aware our valvetrain was that shitty?

Every Part of the drivetrain is pinned at it's maximum. I realise that it's a fully built Protege. Even so, The tranny is just not good for High Speed. I've accepted that the car is geared for the 1/4 mile and bought a Porsche. Do the same man because I would rather see you spend $3000.00 On an old Porsche than rebuild a Built Motor for $6000.00

I'm not being a H8TR, I really do understand the quest for speed, but I just don't want to hear about a Zoom Zoom Boom on something as simple as proplonged Overreving, (What Killed My MP5T the first time as you might remember last October)

Yea your probably right... I wasnt up near the top for that long, but its definatly something I will think about before i re-attempt such a run. I love driving my car (and having a car to drive) too much to risk losing it due to my own shenanigans.

[Brian MP5T]

Believe me, it hurts and you have no one to blame.

[Hughes412]

Why even ask why? Your on a car forum for people that want to mod cars and are car geeks! Speed for most people on here is what it's all about. Now I don't think even with 300 hp a protgeg could do it just because of the aero dynamics of the car. But I could be wrong. I hit 147 in my Z28 with the tops off. That was a windy ride but man the rush of it was bad ass.

[MoJoeTCM]

who the hell uses their brakes going over 150...that is plain stupid...you know how fast the life on brakes and rotors deplete when doing that??!? if you are going that fast you should have enough space to coast then brake....even if there is a cop...dont brake....just keep going....by the time he would hit your speed you would have over a 3 mile lead.....anyway.....using your brakes to slow down at that high of a speed is just asking for new pads or rotors by next month (if this is your weekly ritua)l....i dont know what to tell you...it is your car.......just advice....

[MoJoeTCM]

nice analogy though...

i know pirana has been up in those numbers in his nsx. perhaps even higher.

Actually, Pirana ran a AMG Mercedes, and was over 150 MPH with it when he had the old P5, and the HiBoost kit.

[SpicyMchaggis]

150mph at what RPM? Same with pirana. You climbed to what post 140mph. I just don't see anyone getting outside the gearing, regardless of power.

[LinuxRacr]

Ask Pirana. that's what I remember him saying. He asked the AMG driver how fast they were going, and he said something like 155.

[Antoine]

My kinda project :D

I'm not sure of your current mods...but of course it's possible with the right approach and more money ;) You need the whole enchilada setup for anything over 150mph. Safety first...I would have a full on roll cage in case you go for a spin (literally) and for stability...Tires rated for at least 180mph...upgrade the durability of the cooling system (hoses, fittings etc)...get a tranny cooler...look into a gear change/tranny upgrade...if you're really serious upgrade the valve-train/head...consistent high rpm is going to take it's toll very quickly...tape up any unnecessary openings and gaps on the car...fab up a custom front air dam to help get those few extra mph...monitor vital engine functions like a hawk without taking your concentration of the road!

There are several legal ways to test the top speed of your car...Saltflats, Silver State Classic etc...

Keep us updated and good luck! (thumb)

[daedalus]

Antoine - thanks for the vote of confidence and you are very right about the safety aspect. That would be a main priority for me above all else. I just think it would be a really neat goal that would create a really neat car.

I am wondering about the upgraded valvetrain, because my bottom end is bullet proof, but other than a port/polish we didnt touch the valvetrain. Does anyone know what options there are out there for upgrade valvetrain? I know corksport sold eibach valve springs, but other than that i havent heard of anything.

[UnNaturalinc]

That's frickin fast... I've been 150 in a car before, it's crazy. :shakeshead:

I've only had my MSP up to 125. It didn't feel right any faster than that due to wind.

[locomotive78]

the aerodynamics of the 3rd generation protege does amaze me from what research i saw mazda putting out a few years ago. also their chassis engineering is just amazing.

[daedalus]

Wow, those are some famous last words....

Its all relative. Compared to OEM, the statement is true.

[MrDiggler]

I'm thinking you'll definitely need more than 300 hp to reach 180 mph. I'm no aerodynamic engineer, but it's basically function of the frontal area and the coefficient of drag. There's a formula somewhere that will tell you how much hp you need if you know the other two numbers.

Your motor must be strong as hell, because my stock MSP takes quite a while to get from 100-120 (which is as far as I've taken it). I get the impression that our cars are not as "slick" as some others might be.

I'm all for you building the world's fastest Protege, but if you're going to do it please be safe about it.

[Brian MP5T]

I respect your Project, but question the car you start with...

I'm shooting for 180 MPH as well, but the car I am doing it in is already faster than 159 MPH now, I just paid $2500.00 USD for it... WTF.

Tough crowd. Its possible but extremely stressfull on the engine to push it that fast.

Anything is possible with money. I could have a Protege 5 Attack Plane, but I don't make funds to back a project like that.

One thing that is for sure. The final drive will have to be custom made to be taller accross the board. The Engine redline is not really the issue. The car could have the HP required just by upping the boost. It is as he said, Built and not the problem when concerned with Top Speed. It's all gearing which is my current problem with the 944 Project.

Lucky Porsche has fixed that problem for me, The 968 Six Speed transmission is a bolt on to the 944...

[Pirana]

Wow, I just checked this thread and I love it....I think some of my previous statements need back up....I did have an encounter with a AMG on the highway about 2 years ago...on an automatic P5 with the HiBoost kit at about 14 psi. When we stopped the guy couldnt believe he couldnt shake me off, so we talked for some time and his claim was that we were over 150 mph. I didnt have my speedo to check since we stop at 140. But we where definetely past that mark. I cant tell if the over drive on an automatic helps you with the gearing, but it was fast and scary...even though the car was lowered, it felt too light and tracked on the pavement. Didnt do it again.

Regarding the aerodynamics of Proteges, they are like a block, it takes a Corvette C6 405hp and a huge overdrive gear to reach 180mph and then GM claims it is drag limited. I'am not saying it cant be done...since a lot of imports run the Salt Flats at speeds over 150 with some aerodynamic work.

I have done over 165 on the NSX with my friend on his Porsche (his speedo is exact) and this cars are meant to go this fast, they feel steady and solid on the pavement. That noise from your door seal, is the rush of air holding you up, at this speeds my NSXs tires hit the inner fender from the downforce :eek: so there is a lot of forces been enacted, you should take the windshield wipers off, if not they will fly off!!

Good luck! Hope to see your baby fly...no punt intended. ;)

[Danielb]

i miss my 944 sometimes...
definately gonna snag another sometime soon

[daedalus]

Thanks for the insight. Dont get me wrong, I was planning on purchasing an NSX this winter until I lost my job. I think it would be much better to start with a platform like the NSX knowing it was made for that type of speed (the speedo reads 180... that makes me smile) but now due to financial constraints I have to hold off on my dream car for yet another year.

One thing you mentioned was the need for aerodynamic work, and I think that you are correct on this. Removal of the wipers would be the first thing, but the entire car, including the underside would really need to be cleaned up aerodynamically. I have wanted to make underbody diffusers for the car for quite sometime because they actually do make a huge difference on high speed cars like the NSX or orther exotics. Once again, i think projects like that would add to the overall coolness factor of a car built to these specs, regardless of it actually being tested to 180.

[DE31]

http://tamiyausa.com/images/product/210/24250/gallery_4.jpg
thats what i thought of when you said make the underside more aero dynamic.

not sure if that does much, maybe thats there to protect the diffs more but thats what came to mind.

[mspeed101]

Daedalus you have to much money!!! you should donate some of it to me ;)

[Brian MP5T]

E-Bay BIACH!

[Pirana]

You are right...the coolness would be worth it...just imagine at a show, with the car tilted on one side and showing all the diffusers and a sign saying speed limit 180, hehehe. The NSX-R comes with front and rear diffusers to keep air from having turbulence in the engine and front bays.
