Default Finally dyno'd the vette....

All,

This morning I finally had the vette dyno'd. Sorry no baselines to compare to but my setup is as shown below. Note that this is SAE corrected and with NO tuning (yet). I was fairly pleased with the results considering no tune.

Factory PCM Tune
Kooks 1-3/4 LT's with cats
GHL Exhaust
MTI Stealth I Cam
LS6 Intake Manifold
ASP Underdrive Pulley
Donaldson Intake W/Cold Air Cover
TR55 Plugs
Taylor Thundervolt Wires

What do guys think? Any positive comments you may have are appreciated as I'm a still a Dyno newbie.

David at Maxwell here in Austin was great to work with and the pricing was great as well. I would suggest him to the Austin folks here on the forum.



Here is a bigger version

Does my A/F ratio show to be in a "safe" region or is it running a little lean?

Good numbers. You will likely pick up another 15-20 hp by having a full dyno tune.

AF looks pretty good to me...

i dont see a ton to be gained... usually you have a problem is its liek 10-11 range.
than there is power to be had from leaning it out a bit

I'm not too sure you'll pick up much peak HP, but your mid range numbers will definetly go up when you lean it out which helps alot at the track. Personally I'd rather have 10 across the board then 15 Peak and very little or none anywhere else.

Either way, those numbers are better than mine

Awesome numbers

Do you mind if I ask what they charged, and how long it took?
You can IM or email me.

Is it typical to have be leaner at lower RPM's like this graph shows? Am I too lean in the 0-4K RPM range? Want to make sure I'm running a reasonable conservative setup.

-Thanks

Very good numbers!!! Around 1800rpms there is a small dip that might be indicative of a little lean and at 5500 up (the stagged lines ) is I believe the result of the springs.

with a good tune and ported heads you would be over 400rwhp and still have a smooth idle,that car is what you call a true sleeper,good job.

I would definately invest in a tune. It would be well worth it. Good numbers though.
