500 rwhp 6.0.......anyone? Planning an LQ4/9 swap for my thirdgen..my goal is to hit 500 rwhp n/a.
So my question to you guys with LS2's, LQ4's, or LQ9's..how many of you have hit this mark n/a and how did you do it? List your mods and if not your opinion on how realistic my goal is.
Thank you

ls2 block with a 4 inch rotating assy. Probably not the answer you were looking for. However my 402 did make 517.3 rwhp 513.8 rwtq with a modest cam and small for a 402 afr 205 58cc heads plus all bolt ons.
On an ls2, lq4, lq9 364 ci N/A build you are going to need a pretty healthy cam, good flowing heads, lots of compression and every bolt on available. Could see 505-515 rwhp if you don't mind spinning 7000 rpms to get it. 490 rwhp is a lot easier and safer. Don't get caught up in trying to hit a number, select parts that work together well, lots of low end torque, and good avg power that willl make the car move. Peak numbers don't mean a lot, I already went down the road you are considering, and it was expensive. It would be much cheaper to go with more cubes. No replacement for displacement.

Wow didn't expect such quick responses. Thank you allngn_c5, your point about average power is a good one. Just looking at options right now so I can develop a good plan.
Preferably I'd like to see what you guys with actual 364's are putting out, no strokers please..I'll research those another time.
For now..6.0's

You should look at YO-EL 's setup. Its a stalled auto with cartek 4x stuff I think. I am not sure what his numbers are but he is in the 10's. Deep into the 10's.
You got an M6 ?? If so his combo should do 500 rwhp for ya.

I made 447rwhp on a mustang dyno with mine several years back with only 200 miles on the motor. If you add in the % loss with a mustang dyno it did around 480-490 on a dyno jet.
6.0L 370
TSP 2.5 LS6 heads 59cc
Comp. cam 236/242 108LSA
4L60E w/TCI 4000 stall
Edelbrock 1 3/4 step to 1 7/8 with 3 inch H pipe through Borla XR-1s
30lb SVO injectors w/Walbro 255 pump
LS6 intake w/ stock P&P throttle body
I have switched some parts around that should get me at 500rwhp or over but i added a Moser 9 inch so i will lose a little through it.
Victor JR intake
Edelbrock EFI 4150 throttle body
Fast Toys 85mm lid
SD tune
42lb injectors
Yank SS4000 stall
12000 miles on the engine
Your M6 should do 500rwhp if you match the combo right.

My 370ci made over 500RWHP on Vengeance's dyno. 11.5 comp, nitrous camshaft, stock water pump, 9", 17x11's in the rear, blah, blah blah. Made peak power at 6500rpms. Made 46xRWTQ IIRC..
