Turbo conversion Complete

Jason, was that with the Unichip or before? The reason I ask is that your numbers might be alot higher on a different dyno unless Deman has calibrated his dyno differently.
I know Damian was somewhat disappointed twice with the dyno results at 2 different times with 2 different cars and the curves were not consistent with the factory dyno charts. I would say, its safe to assume that you have atleast 20-25% driveline loss. By the time you are done with the proper turbo, you should be atleast 400 crank hp and 450crank torque which are incredible numbers for 15 psi.
Good luck and I can't wait to see the car in person.

Raj,
Good point!
The numbers I got in N/A version were with the Unichip installed...the dyno was part of the tuning process for Deman.
I thought driveline loss was more like 15%? I guess that's why it's best just to use Rear Wheel numbers...no conversion is necessary.
I'm going to be up at Limerock on Saturday June 26th with the NY Metro PCA for a DE event...probably too far for you to drive from Southern New Jersey, though...

Jason, the 15% driveline loss is accurate for a dynojet 248 but not sure what would be the driveline loss on a dynapack or a mustang dyno. Based on everything i have seen, they show more driveline loss, hence in reality your car has more power than they show.
Its a good thing .

Did you install wider wheels and tires to accommodate the greater torque and HP? Likewise, did you install, or did you already have, limited slip differential?

Grant,
I got the larger wheels over the winter in anticipation of the conversion. It's a lot of power to put down and I thought it wouldn't hurt.
On the other hand, it won't be great in the rain. So, I don't go on the track in the rain...big deal!
The car had the stock Torsen LSD, but we switched to the Porsche Motorsport clutch style because we felt it would handle the power better.
Now if we only had that big radiator installed from the beginning!
Regards,
Jason

Alright, somebody 'splain to me how to read this chart. Is this 324 hp/ 381 ft lbs OR 287 hp/ 332 ft lbs??
Anyway, I saw Jason's blur on the track at Watkins and the car is fast PERIOD. Trust me, I didn't need no stinkin' dyno chart to be able to discern that the boy was movin'!
I am looking forward to watching (& listening for that turbo whine as he approaches Big Bend) Jason zoom down the front straight at Lime Rock next month.

In the photo, my old single core radiator (bottom) looks rather sad, pathetic, and not up to the job of cooling in comparison to my new three core all aluminum radiator (top).

Grant,
We're having an interesting situation up at my mechanic's...We've looked at your radiator as a replacement.
But, my mechanic is concerned that with the A/C condensor in place there won't be room for your new deeper radiator. Did you remove your A/C?
Does your radiator have fans, or is it a free-flowing unit without the fans? We're just finding it pretty tight in there and are wondering how the larger/deeper radiator is going to fit in.

The AC will remain - need that here in Florida.
I did forward a copy of this message to Jason Lee at Heritage Motor Research in Largo FL asking about the "tight squeeze" and what if any compromises needed to be made.
