Anyone with an SLP 402 please come in
Please tell me a bit about your setup, a4/m6, what kind of dyno numbers you put down, and if you have been to the track what kind of MPH are you trapping ??
Just a few questions that I hope the answers give me something to look forward to next month.
Any negative comments please PM me, and let me know about any problems that way. Lets try to respect our sponsors on this one. Negative comments must remain in PM.
Thanks for any help in advance.

Looks like its safe to say your going to be around 500ish rwhp +10/-10
02 z28, out of the box L92's, TSP Giant cam, hooker 1 3/4 headers with true duals, Vig 3600 converter, 9 in. Made a best motor pull of 486/468 unlocked. On the nitrous tune it still made 456/440, and on a 125 shot made 594/636.
This was the kids first built engine (17 at the time). I couldn't tell you how many times it came in for routine stuff, and was 2-3 quarts low on oil, or the oil hadn't been changed in 6k miles. This thing still lasted 46k miles in 1.5 years, and at the very end of its life had over 200lbs of nitrous pumped through it within 1-2 months. Also it went from the A4 to a TH350 towards the end. Which eliminated all easy cruising. This kid drove 75 mph no matter what. With 3.70s and 245/45/17's thats averaging about 3600 rpms constantly. This is just the tip of the iceberg. I could write a novel on this thing, but it was beat to ****, and lived to tell about it. Finally the top of a piston blew off, and damaged a cylinder, and bent rod worse than I have ever seen one bent before. When inspecting the rest of the engine upon teardown, we found stress cracks around all the piston pins. When we pulled the pins out and removed the pistons they were actually bent. This should tell you how bad this thing was abused.
30th TA thanks for the links. I am pretty familiar with camaro kids success. I am hoping to do a little better though. Hopefully I am not being to optimisitic
Really would be happy with 520/490 If its a bit lower on the hp side no problem, but I really expect the torque to be around 490.
Thanks again fellas.

Can't go cheap. It's the only guarantee you have to make the most you could. That's all I can tell you.
On the contrary, just be satisfied if you hit 475/475 until you get the money to do it right, then call it quits after your supreme top-end cranks out 550/520.
In the future I could consider selling the AFR 205's for a bigger set if and when the power gets boring. LOL.
475/475, are you nuts ??? My lil 346 made 490 to the wheels, and you are telling me adding 56 ci's that I will lose 15 rwhp and only gain 30 rwtq ??? Holy **** bro, lets see what everyone else says about that one. Thanks for the comments though.
Tell you what, you pay the cost of the better heads and I'll give you the money I get from my 205's.
