What ID is a 155 lb/hr? I have the ID1300 and contemplating going to ID1700s.
Mark's motor has ID1300's. Awesome injectors (although not cheap).

Yea. Very pricey. Like $1800. Just sold mine and going with the ID1700. Even pricier at $2000. Prices like diesel injectors!

Dave Mikels is the guy behind all the power in JA 2.0. The drivability is near perfect. It idles at 750 and will pull from 1000 rpm in 6th gear. This is the 6 year evolution of the LS9 platform. Dave has calibrated my cars for 20 years now. So he is the real deal and really understands the hardware and calibration of engines.

Awesome. Sounds like this car is amazingly well sorted. Which is not a surprise in the slightest.

Hellfire is about 125 lbs lighter and mostly off the front. Hellfire also has 315 tires on the front and the splitter and slightly larger rear spoiler.

That is the biggest mechanical difference between the two cars. On similar tracks Hellfire should be faster than JA.

Mark
Thanks for the response.
With JA "finished", is a new project starting any time soon? Care to offer a teaser at what might be next?

A few photos of JA 2.0 from todays track event at Waterford Raceway. The ambient temperature was a steamy 90 degrees, but JA ran cool (203 F peak) on E85 consuming a tank full each 15 minute session. We will definitely need to bring more E85 for the next track event!

We had a good test at Waterford. I had some good data and some not so good data.

The cooling system worked great.

The ambient air temp was 87 F. On a 15 minute session the oil temp stabilized at 207 F and the oil temp was 231 F.

Now the bad news the fuel pressure is still falling off with high load.

All this data is off my built in Race Technologies dash. It is nice to look at data after the test and have to relay on looking at the dash.
