slp cai, full flowmaster catback, and hooker lt's.car is 94 t/a a4

 

U should be pretty close and if not you can always throw on a cutout and you will more than likely be a bit over 300.

 

Possible.. as mentioned, the cut out might get it. Also, for the times you don't want all the racket a cut out will have - but still want good flow, toss the Flowlessmaster muffler and put on something that's not cluttered with baffles and junk (magnaflow, dynomax, etc).

 

my numbers below on my 96 TA.

and yes, stock exhaust with just a cut out installed

stock auto lt1s tend to dyno a bit less from what i've learned...


edit: so yeah my power adding mods are the intake, cut-out and electric waterpump....

 

My car must be weird.. look at sig... w/home made cai, catback and lt headers i was @ 262hp.

 

Man that is crazy. The more I see dyno results around this page, compared to what little my car has for power increasing mods...the more I believe everyone telling me my lt1 runs alot better than most they encounter...

*edit* yours does seem a bit low for what you have done though....

 

I've also yet to do a dyno tune. I'm sure that will help out. All my other dyno runs i've had knock retard and so on. My dyno graphs look like the rocky mountains.. heh.

 

Somethings wrong...those numbers are very low...even with your current setup...i would expect atleast 320 rwhp or so.

 

lbrowne your #'s are pretty close to mine. Is that with the cutout and waterpump? If so how much more hp do you you think a cutout will provide over a catback like mine?

 

I only made the numbers in my sig with the mods listed but I also have 108,000 miles on her so it's pretty rough to get a 93-96 at 300 horses without a cam as well!!!

 

From my experience the Flowmaster catback is a restriction after you've added headers. I'd go with a different catback or add a cutout for the track.

 

going to do a cut out as well.

 

I have the dyno sheets right here...

My numbers below are with the waterpump, intake, and cut out open.

When I closed the cut out for my final run on the dyno, I hit 280.0 rwhp, and 307.6 rwtq
