Default Clickbait LS3 515whp

I recently had my Corvette (08) tuned on 91oct and here are the results:





As you can see she is pretty healthy...

2008 M6 Corvette
GMPP CNC Heads (Untouched)
Tick Performance Gross Polluter Cam
Brian Tooley Valvetrain
Halltech Super Bee MF103
Texas Speed 1 7/8 Headers
OEM GM NPP Exhaust

Thanks to JBPerformance out of Stockton, CA and Matt @ GP Tuning. Believe it or not, Matt @ GP Tuning made this much power on the second full dyno pull.

What's next?

Drag Radials and some seat time. Maybe some Nitrous in the future 10s? God Willing

Looks good but I would be curious what it started out as and have an overlap of the difference. Also, usually STP correction is higher than SAE numbers.

None the less, if its an improvement, its the right direction

Nice power & build congrats how much compression

Post your SAE graphs still you should be in the 10ths with bias ply and good clutch by the way you will love a 4.10 diff gears make easier off the hole save your clutch and driving around town & highway will be much improved as well thanks for sharing...

I'm a drag racer and I know lower gears like 4:10 will make a N/A much faster. But I'm new to the Super-Charged scene and notice xBoostx so I have a question my Super-Charged Vette pulls real strong with 3;42 gears. So how would it pull with 4:10 gears I have a friend with a boosted GN Buick and he says they won't pull as hard with lower gears. I would think it would by like any other car going 3:42 to 4:10 gears be much faster leaving the line.

I know about STD/SAE and I wondered why it was dyno the way it was but honestly numbers should be near identical.

SAE uses actual temp and humidity factors.

STD uses 60 degree temperature standard, this ensures you can compare dyno numbers from different climates and shops.

The good news is, the day I tuned my car it was 62 degrees HIGH (Nov 30th, South SF) so I'd imagine the numbers in MY case to be within 5whp.

I made 392whp/ 380ft lbs bone stock on another dyno in 2016. I have that dyno graph as well.

My bottom end is OEM and my heads are OEM compression. If I flycur my pistons and milled the heads I might pick up another 10whp but I doubt the 91 octane would be sufficient.

Its very drivable where its at now. This S about the biggest cam you can safely run on the LS3 while maintaining some PTV clearance.

I built the car to run 10s all motor and I'm confident it will do just that.

No no matter if Mustang, Dynojet, Dynopack, Superflow...LS3, CNC Heads, large cam, bolt ons, great tune..500+ whp or you are doing something wrong.

Yes its fast fast but I've owned a 700whp EVO, so in comparison it's mild.

Depending on power level boost likes stock gears unless low power in a heavy car.
