looking for some advice.....with my turbo dragon setup(OVS) i ran 19/42 gearing, 8tooth avids with 156 2.5in 3.0 ptich track. Ride 7-9000 feet. Would run right around 10psi boost with race fuel. Clutching setup was primary 10-72's, spring D&D teal(170/280), Secondary(tss-04) 44 straight helix with red/pink spring(140/260). This setup was good would spin 8000 rpm, good back shift was good, wasn't perfect but was very good for the amout of boost i was running.
Now things have changed....dragon motor is now in a pro and have ugraded to tial housing and external wastegate along with Fastrax porting. Threw in same clutching as before(gearing, track, drivers are the same setup also) but the turbo is spooling much quicker than before and it seems like the motor wants to be loaded more coming out of the hole. Top end still seems very good.(running a little less boost) So i'm looking for some suggestions about how to load the motor more on bottom end yet keeping top end the same or similar????
Was thinking of just throwing a 48/44 helix at it and seeing what that did. Or changing primary spring some. If i do end up chageing to a 48/44 the two that i see on teams list are a 48/44/.33 and 48/44/F. I'm assumming the f is for a straight progressive helix vs the quick change in angle after the 1/3 mark of the helix angle. What is better for moutain riding? Thanks for any suggestions or feedback.
Waas thinking also of throwing some rooster 10 weights in the primary.
