Who has a auto that has made 450+HP NA on a dyno?
I know of a few just want to see who else has done this.
Also post your mods.

 

I had 441rwhp with the Y1 cam from MTI with my set-up with car in sig. I just swapped to a 232 234 598 598 114lobe. The Y1 was harder to tune with a A4. I drive this car everyday.

12-bolt,3.73gears, 3800 stall,tuned for spray and stock bottom 346!

 

I made 460rwhp 430rwtq with my 383 Stroker. I had AS LS6 Heads, 236/240 cam, FLP headers, Moser 12 Bolt w/ 4.11's, LS6 Intake, ported TB, TCI 4400, 4L60e, Under Drive pulley.

 

not sure if you ment stock cubed 346 or not but a buddy of mine just made 492rwhp 532 rwtq with a 427, 4l60e, 12 bolt, cnc'd ls1 heads by AFR, 90mmlsx setup 9:1 compression (soon bo have a F1R procharger) not sure on the cam.

 

S1 LS6 Heads/TR224/LSX/90 = 430RW threw my A4/12-Bolt....
Close to 450RW but my cam was too small....
Still went 10.80's@124MPH at 3350lbs

I know it's not 450 but I got just over 439 rwhp with a 3200 Yank stall.

 

I made around 515rwhp through a TH400. 396 ci , hydraulic roller, 12 bolt spool, etc....Futral Motorsports engine.

 

408 a4 c5 = 505rwhp

 

Talk to Brett(SnakeKiller) He put down 440 before his new set up. Now he is running like 13:1 comp. T-Rex, Stage 2 heads, 4400+ converter, and Texas Speed Tuning, I dont remember what he put down with this set up but i believe it was more, Ill check and get back to you all!

 

2002 Camaro SS

CAM ONLY N/A - 440.5/402RWTQ SAE (Hit 450.2rwhp UNC)

2002 Camaro SS A4

Stock LS1 Heads Untouched
TTP Equalizer V.3 Camshaft
Crane Dual Springs/Titanium Retainers
Vig 4000 Verter
3.73 Gears
TTP True Dual Exhaust
FLP LTs
LSX 90 Intake/TPIS 90mm TB

 

Some of these numbers are plain sick for a Auto car.
It is rare to see them making big power and that cam only graph above by Matt is sick.

I ask because my setup is near completion and is a 410 with a 242/246 598/605 114LSA Fast 90/90 TEA stage 3 heads milled to 68cc's with a .040 gasket for 11/7 or so compression, Kooks 1 7/8 LT headers, and all other boltons. My last 410 setup made 440 HP with a stock TB, weiland intake, and stage 1 LS1 heads. (flowed 270 @ 600) I am shooting for 480-490 through the 4L60 and 4200 converter. I was trying to figure out if it were possible.
From the looks of things I should hit my goals.

Great results and keep em coming.

 

Matts those numbers are crazy.WIth a set of heads you should easily see 480 rwhp through an auto. I didnt think i would see the day where that would happen. Anyway that should be a nice mid 10 sec cam only car ya got there.

 

Ya, the owner is MEATYZ from this board and ls1.com. He's a great guy, I'm glad we made good power with the car. We dyno'd it on 26" ET Streets but he blows them away on the street. We're waiting for some track #s and then we'll slap on a set of TTP S3 AFRs

 

yea no doubt that will be a killer. Damn I need a motor for my car so i can get back into the game.

 

Jeremy I have my forged 347ci motor for sale. Hi-Compression 12.1:1 with stock heads. Motor made 440rwhp through a 12-bolt with 4.56s. Cam only. Stock crank, lunati pro billet rods, lunati dome pistons, king bearings, equalizer v.3 cam, lsx 90mm intake, nw 90mm tb, kooks 1 7/8 to 2" stepped lts. You can take the whole combo

Damn Matt that sounds really good. But Im looking to do a stock longblock cam only setup. Thanks though

 

451/508 in a factory stock 1998 Short Block 346 with just heads and cam, through an unlocked TH400 and 12-bolt. See sig!

 

453/406 here, and after a quick review of this thread, I might be the only person who has done it?
