Carpenter Race Engines

I haven't been to Dinwiddie since I went forced induction. I snapped my lifter shaft and fried my lock-up pressure plate bearing just being naturally aspirated. Lot's of photos at R3P. Do you run Atco?

Here's a mod that would work nicely with your beautiful ports:

stacks

YES ATCO is reopening soon tell me more about the stacks is that part of your ram air kit??
 
Yes, V-stacks inside ram air.... also notice no secondary throttle rod (clean up). I tuned my stacks to boost torque shifting at 7200 RPM. Ideally, you would want a bit shorter stacks if you're shifting at 8000... would need to see your torque chart.

SO WALT explain to me how you keep the front end on the ground with 300 hp and 300 ftlbs and now your making a quick turn throttle

300 Ft-Lbs? I believe Brembo is torque king with something over 280 Ft-lbs. with his turbo R3. I make a bit over 230 Ft-lbs max, but carry over 200 Ft-lbs to 7250. I think TTS has done a 300 HP SC R3, but I'm around 280.

The beauty of the supercharger (with cams) is max torque is at a higher RPM than the turbo, so is more tractable. I changed my riding position long ago, my body weight is always forward. Note pegs way aft... handlebars forward.
 
bett'n that you're not a cheeseball like some here that must be one hell of a ride walt and now 1/4 turn.. christ
 
Sam, I see Joker just made 293 HP & 227 Ft-lbs with Preds & SC... and no intercooler! You should be a happy man! Congratulations!
 
thanks walt... numbers are a relative thing however as you know. it was nice to see a 27 hp and 14 lbs increase but i am waiting to hear on how the bike "feels/responds" compared to before. really interested also on arts testing of the 1 3/4 experimental set i sent him compared to his 2".. be a couple of weeks before i have a "regular" set for him to try as a final comparison. .. course his customer might want his bike back at some point
still i gotta tell ya you guys have a bigger set than me ridding these beasties.

HEY GUYS i think these bikes woud run quicker 1/4 mile times with less torque better traction and not as wheely prone I can tell you this bike is a handfull with stock riding position and no wind protection I wound it up to 7800 in 5th gear and it just keeps pulling and the wind wants to rip you off the bike but its a lot of fun messin with the sport bikes this is the way the original ROCKET should have come from the factory
