Arrow Racing GTR .21 Engine Thread
#1357
Yes. I'm not expecting the best mileage, but as long as it'll go 8 it'll be okay. Kind of expecting this pipe to be a loud big bottom end pipe... I just need to get a good solid tune on the engine and figured I'd give this pipe a shot since I have never used it.
My GTR, though, has ceramic front and rear and a two needle carb... But I can test with the 2060, too... I ran the 2060 when I first got the engine, and it was pretty vanilla, but I had other issues that are sorted out now so I will be able to give some better info. On my Bullitt the 2060 is super smooth down low(I run all al shoes in buggy with 1.0 springs without issue) with a big top end, which is what I would expect the 2060 to do on the Arrow.
Trebber?
yeah, I am gonna be at Indy Saturday working this thing out. Small chance of going to Porter, but most likely will stay in town.

I'm looking at a good buggy motor with a smooth bottom end to replace my OS 21 Max. Too much punch for me to drive the way I want to. This engine is looking to be the best option right now given the price. I have both the OS 2060 and 2090 pipes.

Browse back few pages, mine:
Lsn-flush
Hsn-2.5 to 3 turn out from full close
Msn-1.5 to 2 turn out from flush
Idle gap factory shud be .7-1mm
If engine stall after fire up, lean lsn a bit till idle good, if u had some experience, reduce the idle gap.
After break in leave the msn, it will give good torque, lean it for mid/top end
Maybe others will have better idea
