180 track car project

if the torque is at the wheels, that is very good - check tho, it could be fly.

165bhp at the wheels is good also for a car with std cams.

Dissappointing though that so many horses have escaped despite decatting and inner wing filter...down to 166 bhp (165.9) with 156 ft/lb torque.

there was a definate pick up at 4250 as the power valves opened so I am going to jam oped the power valve and take it back on the rollers to see what effect that has on torque curves

can you post up the graph? might not be all that bad

balance usually opens at 2980rpm, so the only losses (assuming all else works) will be below that - on track, you'll never be that low in revs anyway.

[Mark S]

have you sold it then?

Sold?

Sorry not a great photo....



The figure is calculated at the flywheel on run down from the road. There can be a lot of variables in this and it does all depend on how a rolling road has been set up so I could go to another RR and make more...or less...all depends.

As for sold, it "might be" I took a deposit on it today so we will see if it pans out. I decided to move it on as I was keen to build another track project but couldn't justify having two track cars and needed some extra funding for the new one. In addition, Silverstone left me a bit dissappointed with the car and I've been giving myself a hard time over it. It was clear I didn't know as much as I thought I did and to get the 180 where I want it to be wouldn't be cost effective. So, I put it up for sale, kind of hoping no one would buy it and I could then justify spending a shed load more cash on it and getting it where I wanted it to be...it backfired on me as I have had a lot of interest in it.
