Default H/C Z28 on Dyno

Wanted to how it did in street trim on the heavy 18's. Went 440/410 at the rollers. Ported 241's, 234 duration cam, and a typhoon intake, going to go back to the Ls6 I think, the FAST are expensive. Car has custom duals with flowmaster mufflers. Thank you for watching.

Sounds good but the flowmasters are holding you back.

Thanks for the compliments. I like how it turned out. The mufflers are flowmaster 40 series. 3 inch piping with an X.

those numbers seem real high but thats awesome i didnt think that having a 234 cam and ported 241's would pump out that much power

Yeah impressive. I would not mess with the intake putting those kind of numbers down.

Nice numbers!! If you end up pulling the typhoon off i'd be interested in it, pm me with more info on which one it is.

Thanks again. I was looking for my graph and I do have one. The graph he printed read 435/406, so not quite best pull. The curve is very flat and carries very well. I think it was the "longest" pull, I wanted one that covered as much rpm as possible.

Also, I found out from the guy I got the typhoon from that he ported it. So maybe it isn't that bad after all and helps explain the numbers a bit.

The flowmasters are not holding him back, the catback setup flowmaster is a restriction not on duals, does sound good,nice numbers but we need pics now, i have been thinking of switching my sweetthunders to something else i want something with more tone, how do you like the 40s?

One guy gained 40 horsepower by simply removing his flowmaster muffler. Not saying his numbers are bad. But can improve.

Very nice numbers on 241's OP
