Setup is gutted 89 CRX (~2000lbs with driver), stock block GSR/ B16 hydro tranny DBB 50 trim @ 10psi (boost was about a pound or so low from alt though while at the track) and i was running 205/60/13 M&H street/strips. they didnt hook as good as i had expected, or maybe i was expecting too much. i left my driver skill at home i guess.

judging by these time slips, what power should the car be making? made 345@10psi and im not sure of the altitude but its higher and def. causes boost to be lower then whats normally set. want to know if its gearing, driving and/or altitude thats hurting the car. car was hitting rev limiter in 4th at 8500 by the 1100ish foot mark, on the quicker run i let off and coasted the rest ,on the faster run i put it in 5th for the last few feet. should i run bigger slicks to compensate for gearing or switch to a GSR tranny?

Hard to see the slips.

 

slip on left:


60' - 2.020
330' - 5.437
1/8 MPH - 91.70
1/8 mile - 8.098
1000' - 10.374
1/4 MPH - 114.50
1/4 mile - 12.276


slip on right:

60' - 2.024
330' - 5.637
1/8 MPH - 90.09
1/8 mile - 8.379
1000' - 10.686
1/4 MPH - 116.42
1/4 mile - 12.595

 

~115 mph in a car that light is prolly 225-240whp.

i should probably rephrase the question.

the car made 345@10psi but im trying to see how much altitude affects power and/or if the gearing is hurting me.

 

Go with a bigger tire, raise your rev limit

thats what i was thinking with tire. its a completely stock motor, not sure how much more then 8500 it will handle and i dont want to oil the track down

 

when i was running our shop car (99 gsr) we were running 11.9 - 12.1 @ 119 mph. We were on 24.5 onch slicks and maxxing out 4th on a stock gsr tranny revving to 8K. if your running into 5th you need to change eather tire size or the tranny its self for a longer geared one.

you were maxing out a GSR tranny with 24.5's @8K with 119MPH?

i think i might have to try out an LS tranny

Get bigger and better tires. You need to cut much better 60ft times than 2.0+. I think with better slicks and more seat time youll be much happier.

 

E.T is hurting from poor traction (60' and 330' times reflect that) and hitting the rev limiter on the big end. The MPH does not reflect 345whp but, you said you let off on one run and shifted to 5th on one. Both of those actions probably robbed you of some MPH so, we really can't give you an accurate estimate of your power output. As for your tire size, a 24.5" tire will yield you approx. 128mph with the B16 trans and keeping the limiter at 8500.

That doesn't sound right to me either cause' I went 126mph on a GSR trans while running 225/50 (23.8" tall) and only turned 8100rpm.

you sure about the 128? the tires i have on there now are 22.6" diameter and im only able to trap 115 on them with 8500 (assuming im not loosing alot of MPH from letting off).

It's 127.2 mph to be exact (not factoring in any tire growth).

it was for sure close to 8K. Also this was on stock tach. I know auto meter tachs read about 500rpm less thatn stock gsr tachs. It may not have been 8K but i know it was close. Its been 4 years sence I drove that car. Kinda funny I was in 4th before the 1.8 mile and pulled it the rest of the way.

 

OK heres my 2 best runs, i guess i missed 3rd pretty hard on the 116. maybe i just suck at driving

get a 15"rim with some 22"slicks + more seat time = better time ......goodluck

 

its not you, its lebanon. i was there 2 weeks ago and it was total trash. 400 hp cars, mine included were just knocking on 120mph. the track has been worse than normal, and the tree is fucxxed up there too. last night as well the tree inconsistant and the track conditions were crappy.


that said, gsr trany and maybe 23 or 24" slicks. dont get the 22's and a longer tranny, you will most likely spin those tires especially if you are launching with boost

yeah LVD is notorious for being a slower track, i didnt think it was that bad but apparently it is. i might try e-town on my next outting becuase i know thats a great track.

im gonna up the limiter to 9K on these tires/tranny i already have and hope for the best. according to calc it should be good for 124 which i dont think a 350WHP car is going to go anyways.

not sure how they are with you but the techs were being retards, they were like well this car has an aftermarket turbo you need a scatter shield and a roll cage and a fire suit. i was like the car isnt going 11.49 so i dont need a cage and then my first pass i went 12.4 and they pulled me back into tech while they read the rulebook to try to find a reason to kick me. stupid ******.

 

Dont get disappointed, just get your driving skills down. Every track has good and bad days, as well as most drivers. Rule out all of the variables such as missed gears and/or letting off. Get a good track, and get a couple dozen good runs before you make any assumptions.Shoot John at M and H tires a email and ask him what he recommends. he know tires like nobody else!

 

the techs are always ******** to me cuz i dont drive a mopar. mainly the bald guy. i hate him. the other week he had his hand over my bov at idle trying to tell me its leaking and fail me.

yeah and they are all about the scattershield now. i talked to some people last night that they were giving that line to....

 

lebanon valley is not that slow, e-town is usually better traction though. my buddy rans his dc2 gsr there last night and did 12.7 @120 on cheesy 195 street tires. making 350-360 whp on our dyno.

yeah i talked to him for a little while last night. the car was nice. one of those runs he came out of the hole harder than other runs and was spinning into 4th it sounded like.


imo, lebanon has been getting worse over the course of the year

yeah the track prep is usually very weak.

 

the new fat black guy is the one who hassled me. "ill loose my job if your flywheel comes through the firewall and cuts off your leg"

give me a break. i bet if i had a scatter shield he wouldnt even mention the fact that i need a non OEM SFI approved flywheel for going 11.99.

im not putting a cage in my car till i absolutely have to. ill get a scatter shield to passify those idiots. E-towns tech is not nearly as strict, or it didnt used to be.
