Dynoed my LE1 Setup.
Got back to the dyno again this weekend. Last week with a weak fuel pump i made 318 hp/339tq with an 18:1 A/F.
This weekend it rolled 380 hp / 350 tq. Over all im pretty happy with it. Guy who did the tuning said with my heavy *** 17x11 replica wheels i was probably showing 10 - 15 HP less.
Tq curve was pretty flat, starting at 2700 rpm it was ~310, peaked about 4500 rpm at 350, then dropped to ~310 at 6500.
HP was a steady climb to about 6100 where it leveled off and stayed to about 6400 when he let off.
Over all im very happy with it.

Re: Dynoed my LE1 Setup.
A local guy did the tune, picked up about 10 hp, and a lot of down low tq over my mail order.
The guy who did the tuning said did a before and after of someone with stock wheels to an after market 17x11 and the difference was 12 hp.
this was from a stck 16x8 wheel.

Re: Dynoed my LE1 Setup.
Actually, i went to pro dyno in phoenix.
There is a place in tucson called Apex that can dyno, but i wouldnt trust them to tune.
Nic, a guy that i found on one of the local boards was able to tune it for me. He did a good job and really seems to know his stuff. My friend may send his car to him here pretty soon.

Re: Dynoed my LE1 Setup.
I am glad you got the car running right. I bet it feels MUCH better.
It would be tough to see 15 more HP from the wheels but ya never know. I would think about 5 HP would be it but heck, even at 380 RWHP you are making GOOD #'s for a cam that small.
Get to the track with some sticky tires and see what it'll do.

Re: Dynoed my LE1 Setup.
I think the drivetrain loss is closer to 14% on an M6 transmission. (10% would be too efficient 
) The 285 HP might just be a bit underated. With a 14% loss, 380 RWHP is ~ 441 flywheel HP.
Jared, can you email me the before and after graphs?

Thanks.
