Will have complete breakdown of data within a couple of days, but here is a comparison of power from Mayhem to Hellfire.

In sticking with Mark's theme of 'more power + less mass' it is certainly directionally correct.

Some statics of Hellfire engine:
Average TQ from 2100-6800 RPM = 871 #/FT
Average HP from 2100-6800 RPM = 726 HP
Peak TQ: 950
Peak HP: 931


For fair comparison, compared to Mayhem over same range (3900-6800 RPM):
Mayhem Hellfire
AVG TQ 765 847
AVG HP 772 852

More to come - much data to process.....

Dave

For those of you who don't know Dave Mikels he is the brains behind my power and success for over 24 years. He did the engine in our FSAE car back in 1990 and 1991. I did the chassis and Dave did the engine. Huh same as now. Dave is also a great driver so we have been a good team for a few years. We were roommates at Rolla, MO

The years I did well at OUSCI it was Dave in my window telling where to pick up time in the Auto-X. Not my best event but I can do when I need to with a good spotter.

So we are at again. I think Dave will get it all sorted out! Looks good so far. I'm going to need more chassis to put all this power down.

Mark,

Care to elaborate on what you mean by needing "more chassis"?

I need to get it running to sort out the spring, bars and dampers to handle the new power and front weight.

Wow! Very nice.

HellCat vs. HellFire... If only...

Push on the "go pedal" and you'll look like this!

Gotta love that torque curve. I can see why you are saying you need to get the chassis sorted out. You should be able to put power down anywhere that you can maintain traction. Will make the AutoX and Speed/Stop more interesting.

Time frame on when you'll be able to start your tuning?

I made a lot of progress over the weekend. I got all the parts back to assemble the rear axle. It has a C&R Racing Remmed gears that was run in at C&R axle dyno to make sure the frictional loses are good and it is quite. The housing is a steel Strange Engineer part so I could install the diff cooler. All the Detroit Speed brackets are welded on it. The axle ends are my design that uses the SKF bearing, production C-6 park brake and all C-6 Corvette mounting interfaces. The axle ends are dry due to a GM axle seal in the end of the axle tube in the tube end. The axle shafts are 300 M material that are gun drilled to save a little mass. I was also able to design a park brake cable that interfaces to a '69 Camaro so you can use the stock '69 Camaro park brake system.
