Hey guys. I'm just looking to get opinions on what others think my set up should make and opinions for my next upgrades. Its my 99 z28 A4. Here's my mods:
stock bottom end
Deka Siemen 60lb injectors
stock heads with ported and polished exhaust ports
beehive springs, hardened pushrods
stock ls1 intake
222/220 115 lsa 566/564 lift cam
Melling oil pump
ls2 timing chain
2500 stall
built 4L60E
Richmond 3.73 gears
BMR torque arm
Granetellie 255lph fuel pump
sts turbo ( 60mm ) 7-8 psi
tuned speed density

This car has come a long way in the past year. My goal is to get around the 500rwhp mark and more importantly get some solid 11 second time slips at the track on mickey thompson e.t. streets. I do drive the car around alot and occasionally to work on nice days so I am trying to keep driveability as well. I do want to upgrade to an LS6 intake and 243 heads at some point because I'm sure those are holding me back along with the turbo. so my questions are
what rwhp should I be now?
how much would I gain from LS6 intake and 243 heads?

Thanks for any opinions.

 

Wow, looking at your mod list, I will say the ls1 heads and intake should have been among the first things you upgraded. I'd suggest at least a fast 92 intake and a set of prc stage 2.5 heads at minimum. The fact that you're turbo'd means you're really gonna wake that car up with better heads. Iirc, I've heard the even ported ls1 heads aren't as good as stock 243's.

 

I think it would be safe to bet you would be above 250-260rwhp. Good luck..

 

Its definitely been a work in progress. spent a lot of time working bugs out. I've just been doing a little as I go. Hopefully this winter I can do a few more things to it. just trying to get opinions right now. thanks

 

470-500rwhp.

 

Hey man if you want something already built you could buy the Camaro in my sig. I drive it all over the place with A/C, heat and leather seats. It has gone a 9.90@134 in the 1/4 in the heat on a 150hp shot of juice. Normally runs mid 10's on motor @126-129mph depending on air..Best motor pass in November of last year was 10.39@129mph worst motor pass in the heat so far has been a 10.72@126mph I ran this the same day the car went 9.90@134mph with the 150 shot of spray.. In good air on the spray it should run 9.60-9.70's.. The motor is a LS2 402ci, Th350 tranny, Strange 12 bolt and full BMR and strange suspension..

 

sounds bad ***. wish I could afford that right now.
