My camsprockets are set at +4,-6 i ran a 14.4@94mph(14in. street tires)....why is my mph so low... shouldn't I have a trap speed around 98mph...

 

ummmmm, turn those sprckets back a couple degrees. Unless that's where you gained the most power ON THE DYNO!!!

Plus, that trap speed looks about right.

u probably have a big curvve at midrange, very good for street!

 

I dunno...but I hope that those cam gear settings are dyno proven? Those are some very odd numbers. I dont know about your time. What was your 60' times? I ran 14.4's with my B16a in my hatch some years back with stock 14"s. But my 60' times were 1.9-2.0 and trap speed of 97.5-98.5

No the cam gears are not dyno tuned...i just put it at +4,-6 and ran a I1=2.321 I2=6.190 I3=9.379 MPH(I3)=77.631 I4=12.111 E.T=14.475 MPH=93.975 Jason, how did you get 1.9-2.0 60' times with stock 14's...i could probably get a 1.9-2.0 60' if i had slicks...Yeah i have some ******* low and midend power 1st and 2nd gear revs up like a motorcycle...but when i hit 3rd...thats when it feels slow...Yeah thats why my car feels hella fast in the streets

 

I dunno....but they were on some going bald from too many burnout stock tires. I guess that I am a good driver. I have yet to not better any of my friends times in their own car. I have the time slips from the track a couple years ago. I prolly have like 10-15 with 1.9-2.0 street tire 60's.

 

How many lbs does your car weight w/driver...i think i am getting 2.3 60' cause my car weights 2600 w/me...or maybe i aint launching it right...what rpm did you launch at???

 

My car weighed at the time....2550 with me in it. I launched it around 2500-3500 for those times. I eliminated wheel spin with the low rpm launch, but I had to be careful not to bog the car.

whats the psi on your front and back tires

 

Front was at 20psi and the rears were at 35psi.

 

Your gears are way too far out. If you want to tune them yourself, change them in 1 degree increments starting with the Intake cam first, then to the exhaust. Do back to back runs after each adjustment.

It takes some time, but you can do it yourself. Most people don't ever go past 4 degrees unless they are running some seriously high lift cams.

 

i don't think a gsr tranny is the best all motor hight trap speed tranny. a del sold or type r tranny has much shorter gears giving you a better top speed.

the gsr tranny is the **** in boosted applications.

perhaps for better trap speed, lightened flywheel, drag radials, and nos.
