Cool

I am looking for a new .21 on-road header for the old style pipes that use silicone couplers. I have 2 new 9886 RB pipes that I would like to use. PM me if you have one to sell.

Thanks, Will

Pretty sure the 353 has a diffrent bearing Mitchell have a look on the nova site for part numbers.

Front bearing will be rough and noisy when the engines on. Its usually the rear bearing that goes on mine not the front.

thanks Jason, i thought it might be the front bearing as it all of a sudden was a pain to tune. flames out and doesnt hold a tune. i checked the o-rings on the carb and back plate and they looked all ok.

thanks for the info

Mitch

it could be a number of things, but have you checked the pinch on the sleeve? if your liner is worn low compression will make a motor very erratic and cause it to stall once its up to temperature. other then that check the part no. of the front bearing on the novarossi website for your motor, should also have a size of the bearing on the explosion for the motor. also if possible stick with a rubber sealed bearing for the front.

In your opinion what engine would you choose for 1/8 igt/ofna class racing? The S21P5XLT or the N215T engine.

Cool

I would go with the N215T. Its an on-road specific motor and will turn more RPM. Get an on-road specific pipe, 086 series works great, a medium length and short length buggy header to see what works best.

Would I be losing some torque if I go on-road engine? Aren't 1/8th on-road cars lighter compared to an 1/8th igt?

Maybe, but on-road engines make more power everywhere. They have aggressive crank and port timing. You can also move the power band around slightly with pipe choice. Of course you can also gear the car to take advantage of the RPM/torque characteristics and capability. The GT nats open class run by Ipanema was won with a Novarossi Flash or 35 plus 21. Overall good on-road engines make more power everywhere but the powerband is moved higher in the RPM range. Off road engines run out of breath fast on big on-road tracks.

You need to think complete package. Clutch setup, pipe and engine combo, then tune for the traction and length of track.
