Pedro, Wicks Aircraft supply has the Thermocool product discussed previously. www.wicksaircraftsupply.com I also cut 2" off my lower cowl lip to give the pipes a bit more room to exit without melting the lower cowl. See ya!

My old exhaust system had to go due to cracks, and I'm trying to install a Vetterman 4-pipe system that I bought. My concern is, the ball joint of the pipe off the number 2 cylinder comes to within about 1/2 to 3/8 inch of the cowling fiberglass. Larry Veterman's instructions say that the pipes should be 3/4 inch from the cowling, minimum. Anybody got any experience with this? After all the metal-bending I've down so far, I don't feel like switching to a crossover... and I might end up with the same problem. Thanks, Pedro --------------------------------- Talk is cheap.

I flew alongside him in my 150HP/Warnke prop (at the time) Bandit and could actually beat him by a few knots in a flat-out drag race. The conversion was long and complex requiring 2 months of downtime cutting the cowling, splicing the parts and glassing them on and countless fitting and re-fitting the spinner, plenum and trimming the baffling, moving oil cooler, etc. Then came gear leg removal, wheelpant removal and replacement. Finally in primer we rolled the finished product out and took it up for a test flight with me chasing in my stock RV4. I could still hang with him across the board and had identical results in the flat out drag race....!!! It did run cooler across the board though... Personally, I would take the money and invest it in 100LL and go fly...alot! Did it cost over $1200: yes Was it one big giant pain in the butt: yes Would he do it again...no! My 2 cents...

I closed off about half the room for exit air (where the exhaust exits also) and this allowed the oil to get up to where the vernatherm would keep it at 180. The cylinder head and EGT temps did not change where I could notice. Still running 300 degrees cylinder head temp and 1200 EGT. Thinking about closing off this area more and making it an adjustable closure so it would work in the cooler months. My inlets are still stock. As it is, I can just get up to 180 if I fly somewhat hard and the day is warm........

I've already ordered some aluminum woven silica from Spruce. I'll give that a try, check it flight-flight, and let you know how it works.
