I have the 2.65 upper with the metco idler it works great . That's what the other car switched to as well and has no problems now.

G, I have that one in. Came as part of the TVS package...

That's good I would conclude that you don't have any belt slippage issues then.

Just finished third dyno. Not to shabby, but could be a little better. Only change to the car was re-installing my 1 piece DS, and re-tuning with Jon. We're still tweeking a bit.

645.55 RWHP, 615.79 RWTQ @ 17.83 boost with a/f around 11.9...

So how much gain was there with the one pc DS ? Was it 21 rwhp ?

[gr8snkbite]

yea..20hp. Jon's tune simple cleaned up the a/f and other paramaters. We're still working it.

So you really don't know what gains if any are from the DS itself since some changes were made to the tune as well ?

Explain how you know this please.

[TOMMY GUN]

My driveshaft and BMR loops were put on at a shop that has the dyno we use around here.

After the install it was dynoed.

Sae corrected I got 18 rwhp.

I said around because it was done on a different day than my previous dyno.

Well yes and no ..... I had some problems with it vibrating excessively over 80mph so I had Evo send it back to DynoTech to check it out. That was back during Evo's party....no word on it yet. I've been running the stock DS all this year with no problems.

[TOMMY GUN]

[gr8snkbite]

one dyno-tech failed, yours excessively vibrates...is there something going on here?

i can't truthfully say i gained 20 just from the DS. But i'm sure it's close to TG's numbers. Main thing for me and Jon was to get the a/f back into spec. But i'm sure i gained a few from his tune also.

I just emailed sales at Lund racing about the header tune, I didn't have a direct email to Jon Lund.
