Went back to the track last friday cause it was cooler low 70s upper 60s and the car ran slower than 3 weeks ago when it was blazing hot!! WTF!!! I dont know what is wrong with it....I got a good 1/8 but the car has no top end!!! Then again i pulled a IX by a car lenght saturday night and he has the same mods i got.. I even pulled another IX also yesterday that has more mods than me and hes one hell of a driver!! Heres my times... The only thing that i can think of its a boost leak or the car may be pulling timing on the top end

Welcome to my WORLD

 

Looks like it's pulling timing to me. 19mph on the backhalf is less than stock for crying out loud. Check the tune IMO.

 

Thats what im thinking but then again i ran 2 Evo IXs and i put a car on both by the end of 4th and one of them trapped 110 on friday night so i guess the car just doenst run good at the track

 

Ok 38 views and only 2 replies? Common guys i need imput!

 

well I can tell by your short times that the shifting needs work, but thats not telling the whole story as to why your car is seriously slow up top.

First off do a boost leak test up to 24-25psi. If your still running that stock BOV I'd bet thats one of your major leaks.

Did you log your runs? Was any timing being pulled? If you had zero knock you should be able to add a couple of degrees from 5500 up until you start to knock in 4th gear.

 

you have to go by your times at the track. you said your car seemed faster before the clutch was installed and your times were much better before your clutch?so maybe something is wrong how much boost were you runnin?correct me if i am wrong?

Yes im still running the stock bov... I dont have anything to log the car with as i will have to take it to TTP-E so we can log it and see what the issue is.. I have ran 12.5@110 with tbe, mbc, o2 housing, manifold and flash that is all.. Now that i have a fuel pump, clutch and flywheel the car is slower... Im trapping anywhere from 86-87 in the 8th but the car has no top end at least at the track it doesnt.. I pulled a IX by a car length saturday night and hes got my exaxt mods and Exedy twin disk and he trapped 110 on friday so i dont know what its going on

 

Needs a retune after fuel pump upgrade. New pump makes more pressure , runs rich on top

 

i did get it retuned

 

I also wana add that after the first run that i trapped 107, someone later had spun out and they were cleaning the lane for more than 1 hour... I wonder if that had effected my times as the track not being prepped correctly since all my pases where on that same lane??

 

Do you think you could have had a bad batch of gas in the last couple of weeks?

 

i dont think so... What i dont get is why does my car run like crap on the track and it runs different on the streets.... I need to do a boost leak test sometime this week and see what the hell is wrong with this car

 

Was there any wind? Sorry I have to ask cause wind killed me one day at the track this year. If you cant log your runs try throwing some race gas in and running. That should prevent timing from being pulled if thats the problem.
