Put the 5.0 on the dyno :)

So i only have a tune and mufflers and ran 400 at the wheels exact:banana:......what do you guys recommend as my next mod, intake, mid pipe or something else?

 

[z28th1s]

Nice numbers, congrats :beer:

A CAI and O/R midpipe should put you in the 420 - 425 rwhp range.

 

[jas11151990]

400hp and 387 trq ... my sheet is in the car still ....... what do we normally dyno at

 

[z28th1s]

Mine dynoed at 423 rwhp and 401 rwtq with JLT CAI, Lethal Performance O/R X-pipe and a Lethal Performance 93 octane tune by Jon Lund.

My car picked up 15 rwhp and 9 rwtq with just the JLT CAI over a drop-in K&N filter in the stock air box. I dynoed the car and then installed the JLT while the car was strapped to the dyno and then made another pull.

Just for comparison sake because you asked. 100% bone stock.

O/R X is your next best mod.

 

[SID297]

i went with the flowmaster catback pn-819112 it came with x pipe also . sound is awsome

400 RWHP with just a tune and no other real modifications (mufflers don't count) seems high, IMHO. That was dyno'd in 5th gear?

Absolutely correct.

We had a dyno day event weekend before last (3/12) and the O/R X, tune CAI cars were all around 400WHP.

OP - got any graphs to post? Was this SAE or STD numbers?

Every dyno will read slightly different. I wouldn't put too much into the numbers. It is a tool not unlike a ruler. Track times will tell the tale. ;-)

 

[jas11151990]

?

 

[jas11151990]

its a good motor and put out good numbers if you dont agree then dont post please

 

[Bdubbs]

Nice number, but why don't you want to post up the dyno graph?

 

[jas11151990]
