my truck is friggin slow..help me....
 
super b, 130 hp inj, intake horn, airaid, drag comp on 5x5, smarty on #8, 4.10 gears w 35's ran a 16.05. 2.15 60 ftr........im so ashamed......

last time w/o the turbo ,inj and 33's i ran a 17.60....that was really pathetic

any 24v guys got any ideas......slower than i thought it oughtta be. makin bout 35 psi...runs good and strong but just dont git after it hard enuff.....trannys good

2.15 60ft indicates a pretty slow take off. Are you doing a 4WD boosted launch? Is that turbo lighting quick enough? What RPMs you turning at the finish line? Doesn't sound right. I've never run my truck but I used to do a lot of bracket racing and I don't have 1/2 of what you got in your truck and I guarantee I can hit a high 15 in my truck (well after I get a tranny that is).

Well something isn't right. Even with a 2.6 60' I can still run a 16.1 at 88MPH. and that was with just an Ez and my injectors. with a six speed to boot. Like ^ said are you doing a boosted launch in 4wd? To my mind 35PSI is a little low with the fuel your putting to it. Maybe your wastegate is opening too soon?

NITROUS and a 3rd gear boosted launch. with th e4.10's you're not gonna be very fast. find someone to swap you for some 3.54 and you'll pick up a bunch i promise. you should be in the 14's. what clutch are you running??? what's your charger measurements??

i got 35's w/4.10's...boosted 20 psi launch..4wd. i was about 89 mph top end

i just swapped out the 3.55 for 4.10 actually cuz i do so much towing

kazairl 11-01-2008 02:57 PM

Is your tranny stock or aftermarket? I would start looking at that next I think. For a boosted launch you should have a faster 60' time than that.

triple disc. full comp parts cept for the valve body. revs dont skyrocket when it leaves. it aint slippin. torque mangemant under smarty control

That torque converter could be slipping. My triple disc only lasted 9 months. So just because you have aftermarket transmission parts dont over look that as the problem.

Sounds like a boost leak, or a weak injector pump.

if the pump was weak would it smoke like a steam engine....but im gonna look into the boost leak
