260 to 270 rwhp?

FoxRod87 · Nov 22, 2006

I have an 03 gt and the mods are mac 75mm tb and c&l plenum and 85mm mass air and an open k&n filter, off road bbk x pipe and flows. also have 4.10 gears and an sct tune for all these mods. I am thinking around 260 to 270 rwhp does this sound about right. thanks.

255 would be pushing it with those mods imo.

03ghoststang · Nov 22, 2006

a rough estimate would be around 245-255 unless you have a factory freak then it may be more

What can I do to get more power out of it?

Crzyhrse · Nov 22, 2006

Some long tubes will net you another 15 RWHP.

Scorcher2005 · Nov 22, 2006

ported heads and 262+ cams will get you there, prolly around 270-300rwhp depending on tune, cam size, extent of head porting, and type of dyno.

03ghoststang · Nov 22, 2006

long tubes and a set of bump sticks with a retune will net you around 280+

player4lifeov · Nov 22, 2006

with some cams alone you can get 20-30 rwhp, then you will be around da 270/280 area. Right now i would say no more than 245/255

My 03 made 246.5 with

Plenum/w Spacer
75mm TB
CAI
85 mm MAF
SLP Loudmouth Catback
Diablo Tune

yea you wont get 260 unless you have the long tubes and a tune then maybe. Heck with my exhaust mods and the intake mods i only put down 232rwhp which sucked but o well. I think the MAF hurt me though. Cause im pretty sure my times dont show only 232 at the wheels. IF i had to guess mine though with my tune and the intake off i probably have about 240 or a little more. Im not too concerned about numbers though its all about what i get on the track.

I have all the little supporting mods and tuned the car as great as one can get......268rwhp and 304tq....out of an auto.......The long tubes with a five speed with your mods will get you near 270 hp to the wheels......I think 280 out of the old auto without cams is possible......I will be installing the Granitelli COP's and a canton windage tray to see if I can clip it.....

Yellow2002GT · Nov 23, 2006

And with another 8% drive train loss compared to the 5 speed........That equals about 282 rwhp.....the highest 2 valve with just bolt on's and no interal work is 283 rwhp and 312 rwtq through a 5 speed!

Add more air and fuel. Supercharge it.

save your money and swap to a 5.4 3v or 4v. it takes a lot of money, but then supercharge it and look back at your 4.6 buddies.

Go with some Long Tube Headers, by far the best bang for the buck of all the mods I have done... Definately worth it!

260 to 270 rwhp?
