Ami's Turq Monster dyno'ed

[Paul Workman]

512 HP @ the crank!

Ami's curiosity regarding her ZR-1's HP finally satisfied.

Ami's Z has a history of owners and modifiers before it came to sleep in our garage.

Lots of stuff including: headers, porting (somewhat conservative by "modern" standards), cams, B&B cat-back, SW X-pipe, 3" exhausts, coil-overs, roll cage, diffuser, Hurst shifter, 410 gear, and LED conversion (in progress). But, often asked (usually soon as ppl hear it idle), "How much horsepower does it put out?

Yesterday, with the help of Marc Haibeck and the Dynojet at D&M Corvette, Ami could fill in that blank! On first pull it made 433 HP at the wheels (graph to follow when available), and after some adjustment to the timing, the final pull put the (stock bottom 350 cid LT5) at 435 @ the wheels & (app) 512 hp @ the crank (using 15% power train loss). We all were very pleased, knowing too there may be another 20+ more to be had IF and when the heads are also ported, including along with bringing the rest of the induction to "FBI spec"

The pavement was wet from a passing weather front, so we didn't get to play on the way home (drag radials, ya know...). But, the air WAS a cool 68º and she was feeling very frisky - looking for trouble should we "let the dawgs out"!! Another (dry) day will come.

Is the 512 hp crank HP?

Now I know who "not" to mess with my Turq. Looks so familiar on the D&M Dyno.

Good numbers. Do you have a Dyno graph too post?

How much hp do you think the cams are worth in your current setup?

Pete has said in the past that his cams are worth 25-30. Marc's web site indicates about 25 HP bump for ported heads on an LT5. So, thats why i think there is some "low hanging fruit" to be had yet in Ami's Turq Monster.

Paul, have you ever driven a car with "cams"? I suggest you do before making that leap.

Yes. I have the unique opportunity to drive two Z's w/ practically identical rear wheel hp; one with and one w/o Pete's cams. That said, one Z has 410s & the other the stock "345s in the differential. And, they both have the same fresh rubber. This lends itself to some interesting performance comparisons, don't ya think?
