Well the off road h-pipe dropped me down to a 14.4 at 99mph down from a 14.9 bone stock on a 98 cobra

i really hope you ment to say 13.4.. can you tell me what your 60-foot times are? also what rpm do you shift at ? is your check engine light on from the off road pipe? the removal of the cats will make your computer thinks somthing is wrong and it will pull timing ..did you get MIL elminators for it ?

Well the bad news is the time was a 14.487 at 99.12 mph..Yes my check engine light is on and I do have the MIL eliminators on order for it...here is the time slip info..keep in mind this is only the 7th time I've even raced this car sooo pls go easy on me

R/T---1.191
60'---2.198
330'--6.211
1/8---9.427
mph---76.01
1000'-12.197
1/4---14.487
mph---99.12

This is leaving at 1800 to 2000 rpm (feathering the cluth not to spin cause im running on street tires with 30 lbs of pressure on the rear) and shifting between 6400 and 6600 rpm...Got any ideas?? Help me Gabe!!...I'm giving her all she's got Captain!!

HHAHAHA... OK I'll try to help..
1st off when your at the track reset your computer by UN hooking your battery for a few minutes.. That will get your performance back up to normal until the light comes back on again.. this happened to 9COBRA8's car when we were at the track and we lost 3.5mph in 1 run..as for your 60-foots.. there not horrible considering you only have 7 runs under your belt. I have runs a best of 2.0003 on stock BFG rubber..now on drag radials you can do 1.8s or so ..now shifting.. SHIFT AT 7000RPM!!! i cant stress that enough!! Powershift at around 6900rpm on the tach and get a good shifter like the B&M ripper.. now take her back to the track in a few weeks and tell us what she really runs !!!

I've got the Pro 5.0 but it seems like second and third are a little hard to get into sometimes...could I have not adjusted it correctly?? 7000 rpm...?? Going 1st to 2nd doin that should result in a full-tilt-boogie...Am I at a good rpm on the launch?? how about my tire pressure( does it matter that much on street tires??) I was so happy to get that 14.4 I nearly pissed on myself..

Guess it only gets better from now on out!!

Posted by youl luz (Member # 53) on :

well your launch technique seem to be ok .. alot of people dont like to drop the tire pressure on regular street tires but i do .. try 22-25#s..keep in mind also that my stock cobra convertible ran a 13.8 @101mph stock so your car should be a bunch quicker then a 14.4..let us know how it goes your next time at the track ...

Posted by F8LPONY (Member # 11) on :

Yup, alot of regualr street tires hook fairly well at 28-25psi, I used to get 1.8 60's pretty regular on my stock tires on my T/A, on the other hand with some it doesnt seem to make a difference. I would do like Gabe says and also throw on a set of drag radials or better and bring up your launch rpm if you do and 13's should be a piece of cake.
