Dyno Guesses & Bench Racing Forum - 02 Z28 with a few mods..

I have a 2002 Z28 A4 with 56K miles and 273 gear It has a few bolt ons.
My mods are
SLP Lid,K&N,Smooth Bellow,SLP Y,SLP LM1,Free Mods,Front Sway bar removed,Subframe connectors,Spare Tire and jack removed,Bad Knock sensors.---8.62@84.06,,13.23@106.61

Mods that have been added or about to be added.I will run it again in spring time.
Yank SS4000 Stall,373 gear,LCA's,Both Knock Sensors,TR55 Plugs,MSD Wires,Tune, Weight reduction is gonna be this-Back seat/seat belts,T-Top holders,Drag Wheels with M/T DR's..I might do a 25% Under drive pulley also..

I would like to get some guesses on what I should be able to run in the 1/8th and 1/4 Thanks Jimmy..

What dose the A4 stand for

What dose the A4 stand for

I now you gotta be kidding right Automatic 4 speed..

There are no guesses.I'm gonna say its gonna run between an 7.60 to 7.70.

first off change the knock sensors I bet you could easily gain a tenth or two because when the sensors go bad they pull a lot of timing up top to "save" the motor. also I'm thinking around 7.8 and maybe looking at LOW 12's and a 111mph trap

Thanks man I will let everyone now how it runs. The track I will be running at is only 86 feet above sea level and in oct/Nov it can see -1800 to -2000 feet below sea level. I would be happy with anything in the 7s.Ya I'm changing very thing at once. 4K Stall,373s,knock sensors,TR55,MSD plug wires, I'm gonna do a quite a bit of weight reduction also. I now different cars react to different things. But my buddys 99 T/A with Yank 3500 stall,Borla caback,323 gears on street radails,Lid. did a 8.0s@88mph.

I signed in using Facebook and It changed my user name and everything..

I think next week is when I'm doing everything but I gotta wait till march to find out how it runs..

I'm gonna go pickup a set of Long tubes and ORY pipe today..

I put the LT's/ORY on my car and let say its so freakin loud and I can tell a difference in HP. How much HP can I see with LT's/ORY. I took off the air pump and fittings/hoses and I took the A/C off the car also..

I went to the track after my LT's/ORY/TR55/8.5mm MSD..
Results is..

2.03 60ft 8.45@85.24 12.97@107.88.. Now its time to get my Stall/Gear/Knock sensors/DR's/Tune done..

why havent you done the knock sensors?? not only is it killing performance but could eventually hurt the motor if your not careful

I have never did them ever and The code goes away after 10-20 miles of driving and it stays off for a good 2000-2500 miles. Its been doing it since day 2 owning the car the dealership said they replaced them but the light still comes on and goes away.. I have brand news in my room with the SS4000 stall and 373s to be installed also.

I have did my knock sensors and the SS4000 stall and I did long tubes and ORY. I just did my SS4000 yesterday and let me say its hell of a difference. I'm getting a po757.

That stall may get you into the 11s. I don't know what that that code is you may want to post up about it in the Tuning forum.

Thanks that my goal is 11s. I found out that po757 is common when you change the converter on theses cars. I hooked up my code reader and it says shift silenoid b stuck on. I have seen people tune it out when they tune the car..
