I did a bunch of unconventional things, compare to motors that supposedly make a lot of power but are undrivable turds. Short rod ratio, short manifolds, relatively low duration (310), "only" 48 IDA's, "only" 1 3/4 inch exhaust, etc.
Made 231 at 7500 and probably would have continued pulling to 8k easily based on how the torque curve looked at 7.5k, and it made 75% of peak torque at only 2k rpms. And those numbers are on pump gas, with the belt and muffler on a very conservative dyno. I putt around all day in 4th at 1800-2000 rpms in stop and go traffic and it runs cool. That's my combo ;)

Thanks. Here's to unconventional things.

What kind of heads? Valve size?

The heads are DRD L7's, but with custom 7mm stem Ferrera valves, PAC LS1 springs, and titanium retainers. I got the weight of the valve train low enough that I was able to run only 175 lb seat pressure, and 415 lb open pressure. With Pauter 1.5's I've got .655" lift at the valve. Valves are 44x37.5.

I haven't driven the ol' gal in a few months... mostly just due to laziness :oops:
So this past weekend i fired her up and got the cobwebs blown out. I got about halfway down my drivewary and hit the brakes, and there were none... right to the floor it went! One side of my reservoir was pretty much dry, so I spent a few munutes checking each caliper from under the car with a flashlight looking for signs of a leak. Couldn't find any. The master cylinder looked like it may be the culpret though, so i guess I'll be swapping it and hoping that does it.
I was pretty bummed, i was looking forward to driving it again.

So yeah, the master cylinder was the culprit. I saw some signs of leaking around where it bolts to the body, and then when i pulled it out and removed the rubber boot a bunch of fluid came spilling out.

Here's the replacement, I've had this for years, brand new in the box. Its more appropriate then the one i had since its made for 4 wheel disk brakes.

The caliper is showing the diameter of the new one compare to the old one, its like 2.7 mm bigger. I'm sure the pistons are similarly upsized.

Should give me a bit more braking power.

My next brake project needs to be customizing some cables and housings for the rear e-brakes. I havent had an e-brake in years! :shock: Any of you familiar with the older cars will know how weird the e-brake cable routing is on these cars. Needless to say the brake cables and housings that came with the rear disk brake kit wouldnt fit this car.

I wonder if the pistons are different - like you mentioned..

if so I wonder if anyone has investigated all the options out there and have found and created a comparison chart for those wanting
a "little extra" ... :?:
