I talked to Edddie Sanders Racing yesterday. They claim the HP numbers on the 370 kit is 70-75 with low-mid porting. Do any of you have this motor? What do you think? Any probs/failures with this motor? I'm in the process of tearing down my bottom end and I'm looking for any advice y'all might have as to this motor setup. The PSI 425 is in this same area, but I've heard of some reliability issues on this site. Input is needed.


Thanks,

I can't speak for their 370 but I have their 310 and it screams, ESR makes some quality products!!

 

I was also looking at their 310 because it costs quite a bit less. What carb and pipe are you running with the 310.

 

I'm running ESR's 9 port with the 310 kit and their 5 pipe and silencer. I choose the 38mm air stryker carb.

 

ESR's TRX5 pipe is awesome. I hear good things about their motors too.

 

Their is a 250r engine on Ebay complete with an ESR 370 kit, including carb, but no ignition. The bid is up to 1800 or so and the reserve has not been met, sounds pretty pricy, but the guy said it only had 5 or 6 races on it, but he ran Methanol in it, so who knows. It looks way cool and I want one, even though I sold my 250r.

 

Does Eddie Sanders have a web site? If so what is it?

....I have seen a few 370's run,and man they run like a raped ape.But I had herd that they have a heating problem??I was alos told by a friend that the 370 beats the Curtis Sparks Craptor 690,but not by much,I guess it does a good job of 'hanging" with the 370,but I havent seen it.But ESR does dang good work,and it is top of the line stuff.
