Soo i wanna get a ball park of where im at with wheel horse power. so heres what I have so far...

1994 Camaro Z28

PCM for less

Thrush Exhaust

No Cats

AC delete

I know its way better to just dyno it but there isnt one for 150 miles of where I am....soo thats kinda hard to do :S

 

My guessestimate is about 230 RWHP. Reason: no major power adders to get over the stock rating of 285 HP at flywheel.

 

Agreed.

You really don't have anything major. No headers, CAI, ...

 

i thought they came stock in 94 with 275WHP???

 

sorry im retarded and read that wrong. 230 is prolly right....thanks

 

I don't want to 'toot the lt1 horn', or anything, but I'd say you'd be able to safely guess 240-245 for an auto, and 250-255 for a t56.

I've done way too much research into what bone stock lt1s dyno to ever say a well running lt1 would dyno below 230 whp. Autos typically dyno 230-235 and mannys about 240-245.

A catback/ORY is worth 5-7 horses, AC delete will get you 2 or 3, and a tune to pull it all together will get you (at least) another 5. badaboom, badabing you've got 245-255 rwhp.

 

rob is completely correct,most bone stock lt1s put down 240 rwhp

 

Well thanks guys another question....the guy from PCM for less gaurentees 20whp with tha mail order tune and he said he's got dyno sheets to prove it...is that possible?

 

hmmm....I don't think they could get 20 whp out of a car that's totally stock, but with a few mods like you've got, it could be possible. I wouldn't bank on it if I were you though. If it were me, I'd tell people it puts down about 245 horses, and if it's a little low then you just surprise people with how well it runs.

 

yeah i dont think you will get 20 rwhp out of a tune on a stock car
