Is anyone running the new ESR cylinders....I'm looking into upgrading sometime this year....got a buddy running the old pro x ESR 370+5mm stroker crank...and quad straight rips.....and was wondering if there new cylinders are any good vs the pro x....I was out at the dunes last week with my completely stock 86R and getting smoked....well nobodys really running stock setups anymore...I'm thinking 350 with 4mm stroker setup........any info would be appreciated.... JG..:lol:

A 350 with a 4 mil is a 363. Your buddy has a 350 and a 5 mil making the 370 just an FYI. I had their cylinder I bought it last may/June. Less than a year ago. It ran good with a 4 mil and a 350

Same here, I have the 4mm stroker with the 350 pv cylinder(363) and mine runs good. I have some more tuning to do but overall Im happy.

A friend been running 2 400PV Stroked and a 430PV stroked and all 3 running hard!!!!!!!!!

Wish Eddie would leave the bridge in the exhaust port, IMO.

? not sure what you mean educate me. thanks

Oops, I mean bridges in the intake port. Someone I know caught his piston ring on the bottom of the intake port. Maybe it was an isolated incident, but Honda & CP cylinders both use bridges.

The new and old castings are basicly copies of the a Honda 85 to 86 cylinder, the intake being almost identical. The bridged intake on the Honda cylinders came in 87 to 89 models.,..and yes these are IMO the better cylinders with the better intake design, much more support for the piston and rings.

The CP Industries Sphynx, Puma and Saber employ the bridged intake providing much needed piston and ring support. Unfortunately, the ESR & ProX cylinders do not.
