Guys im looking to enter fighting torque a texas mile style event here in the UK in august. Its held on a 2.25 mile runway. 0mph to vmax in a standing mile with 1/4 mile time/trap speed and total mile time/topspeed recorded.

My car will be making around 500RWHP and similar torque on a dyno dynamics so 550RWHP DJ. The car has 275 R888's and a viscous OEM diff/3.5 FD. 6spd man box.

What do you think I can hit topspeed wise in a standing mile? Ive seen a stock-ish (n/a mod'ed i think??) hit 138mph so what do you guys think I could aim for ??

Thanks.

You should be around the 170+ range...

Other 550rwhp range cars hit in the 170mph range....gearing of these cars may be an issue though...they are not geared to go that fast so you are going to spend a lot of time in 5th and probably 6th....5th is 1:1, and 6th is OD, which does not lend it self to good long pulls like that.

also you may want to make sure you have propper cooling, and maybe make some heat shields around the turbos...they will be making mucho heat.

What do you rev to? 7500rpm in 5th with a 26in tire, and 3.5 diff is 167mph

I have the nimbus heat shields around the APS manifolds the turbo back housings are open and the 3.5" DP's are heat wrapped well.

Im only reving to 6.6K stock DE rev limit.

The wheels are 18" on a 275/40/18 tire.

If i got well into the 160mph range Id be very happy!

thom000001

That should cover the heat.

With that tire and rev you will hit just shy of 150mph at the top of 5th, so you should be going into 6th in the mile. If you get it to just over 6K rpm in 6th, thats about 170mph

Let us know how it goes!!!!!

There was a tt Z at the Miami Mile event... he claimed about 650whp and he was in the 185'smph. No mods on the gearing just boost.

Elperuano

If i remember correctly I believe he went higher than 185, few shy of 200 mph... His 2nd run was more at the number u mentioned.

Flo-ridaZ33

He ran 185mph max...

all his times on the MileMaker-1.com site are in the 175+

The miami mile numbers have been pretty contested by everyone it seems....I have no doubt that car was north of 170-175mph, but don't know how much faith I have in the numbers that timing system gave....especially since some of the numbers have even been stated by some of the competitors to be beyond the gearing capabilities of their cars.
Still fast stuff though.

And let us know how you do.

The only car that was close and then passed the 200mph mark other than the Vette was the red Supra.

Hopefully my car will finally be boosted.. in fact the project starts at the end of this month. I did consistant 134mph passes on minimal engine work and a Nismo V3 wing that induces a considerable amount of drag. I'll keep all you guys posted on the event.. hopefully I'll be home in time as well.

Even with a 3.3FD and 7000rpm's tp play with you would be hitting 6th right at 160mph.

If I had to guess, if you could hook up from 2nd gear on @ 550whp, 160mph easy.

Without knowing the cams you run and the shape of your power curve though it could be slightly less.

djtimodj

Im running stock heads/cams at the moment. Im sure the car will go 160 but how much past that we will have to see :-)

just making sure that you had your stock ECU reflashed to remove the speed limiter right?

thom000001

I was above 160 with stock heads/cams....WELL above.

What your front clip at those speeds....ask alberto too

Dont cut the center of the grill out if you use the stock setup.

The black Z I'm referring to had stock cams as well ... even if times are slightly incorrect he was still above 160mph. I'm sure he was close to bouncing the needle of the rev limiter. Dont different year Z's have different FD? He is a 03-05... not sure the package.

In a totally stock 2008 MT 350z i hit the speed limiter 160mhp in 5th just couples hundreds rpm's (7200-7300) before the 7500rpm rev limiter.


I think with 3.3FD and +700rpm, he can do somthing

thom000001

6MT's have 3.5FD
5AT's have 3.3FD

now there are more rev's in the HR's vs the DE's....that is the big diff...HR's rev to 7500rpm stock.
