The car is stock 280rwhp basically, around there... my friend dynoed his 94 TA at 284hp and the TA's are supposed to have like 10 more hp? So actually is around like 270, call it to 265rwhp. All those mods would jump to more than 280rwhp... wouldn't it? L0L

284 seems way high for a car with those mods. The dyno must have been out of whack or something. A intake is good for around 10hp and the gutted cat maybe 5ish. If that really is what he dynoed he has more mods.

For the car to make 284rwhp it would have to making over 300hp, something not possible with just an intake and gutted cat.

hey yo, dude,

First, stop using Yo, it is driving me insane, along with quite a few others here.

Take the Yo'ing to a rice board.
And Most fbodies dyno in the 230-250 range, depending a4/m6, and condition of the car.


And firebird is a v6! Formula is a firebird with a v8, and trans am is trans am. the ram air on trans am cannot be measured on a dyno,

so, CAI, and gutted cat, with headers would not put you to over 320, more like 280rwp.

This is off unless you got an ls1 under the hood.

Proof that just intake and gutted cat made 284rwhp.

And the car i'm talking about has headers, exhaust, tb, and... I think thats it? L0L

Well that graph does say 284. But i'm pretty sure that is not SAE corrected. If it were it would say SAE correction on there somewhere. Usually when it says "actual Horsepower" that means it is non corrected #'s. So his power is probably a little less by 7-18hp.

But that doesn't mean getting 284rwhp is impossible with those mods. I got 281.5rwhp with the mods in my sig. Which basically is catback, cai, and Tb bypass. So with the mods you have and if your car is a M6 then you could have anywhere from 280-295rwhp depending on how well you car is running.

My friend thought that might be what people are assuming, but were at sea level... I live like 5 minutes from the Hudson River and can see the NYC Skyline... so its not assuming, it is. They did say he had "An official Factory Freak."

He did say it was like 50 degrees out so that might be as high as it could ever of gotten... but still, even a 277 basically stock TA is pretty damn nice.

The fact that you are at sea level does not change the fact that your numbers aren't corrected.

Those are my numbers Chris posted. The numbers are actual HP, it was about 50 deg otuside, at 43 feet elevation. SAE is like 273 or somehting. Personaly, I can care less about what my car would dyno at 1000 feet elevation and 70 deg outside or whatever SAE is. Reason I did not want corrected numbers. Raw numbers is what is important to me personaly. Even though SAE mite make numbers go up when its 95 deg outside in the summer, even then im still happy with knowing the actual hp

lol.... SAE will make the numbers [i]drop]/i] even more when it's 95 degrees out. I think you need to stick with SAE numbers for your own clarification. (humidity will also drop you hp numbers, SAE or otherwise)



however... in your defense, my '97 Trans Am dyno'd 275 and [b]278 rwhp (SAE)[b] last year. The only mod was a CAI (essientially equal to a Ram-Air option). Stock cat, cat-back, everthing. Obviously it was a 6-speed (with stock 3.42's), but I also had installed a new fuel pump, spark plugs, wires, 16 hours before the pull. 94 octane gas and a new fresh oil change was also done.

Anything that could have been done was, and it showed a few more ponies than typical stock cars do. I also had a 3.5" Aluminum matrix Driveshaft installed at the time (out of nesessity), but I don't belive it was much lighter than the stock one.

People didn't belive me either... except for the race team I was dyno'ing with... and my mechanic who did the work himself.

I doubt she'd break 270 rwhp even a month later (ever seen plugs with only 1000 miles on them?). Now with 4.11's intalled I imagine I'll pull a bit less (next week) due to gear effiency, although I'm not too clear on wether this would be an artifact of the Dynojet's acceleration error, or due to actual increases in frictional losses. I dunno... just know that it happens.
