so what size injectors do u think i should run with 10:5:1 or higher pistons??my a/f gauge is showing im runnin lean at about 4 grand and almost lean on idle..370's should be fine right

well under idle, you will run a bit lean... becuase the engine is not asking for fuel at this point and time.

what kind of system are you using to tune.


if it helps i am running 370cc injectors on my turbo ka at about 8-10 psi with no issues at all and perfect A/Fr's

i have nothin at the moment..im plannin on gettin 370 injectors and my ecu tuned..

whats a good fule controller to get

S-AFC

But if your gonna be running 370cc's N/A, IDT the S-AFC will cut it...

Great writeup... Not sure, but did you miss pulleys? A comparison between stock diameter light weight and underdriven pulleys would be a good addition.

240-kid

I didn't miss it it's just, our selection is small (~3 total) so you wouldn't really have a choice.....

Asneer

oh, well then I guess ill have to ask, what are you guys running? And what electric fan works the best?

We dont have a LW Pulley "Set" thast what it sounds like your thinking of.
We have had Pulley Sets in the Past, UR and OBX, but since have been DC'd.

obx still make'em look on ebay..i found a set on ther from obx..whats guys afc settings for the lo and hi throttle??

a lightweight crank pulley is a bad idea. for one engines don't come with a crank pulley, they come with a harmonic balancer. the devil's in the details for a reason.

Asneer

ahh. see when I had my impreza, the pulley/ whatever set felt like it gave me a lot of extra power and the engine reved a lot faster. Thats why i mentioned it, but if its not a good idea, then i wont waste my money.

lightweight crank pulleys do allow for quicker revs and result in noticeable throttle response, however they are not dampers. it's a catch 22 with lightweight undampened crank pulleys because they allow quicker higher revs. the problem is that once you reach the higher revs the undampened pulley can be detrimental.

lightweight accessory pulleys are not worth the money imo either.

Asneer

sorry for being retarded but what do you mean by:

"once you reach the higher revs the undampened pulley can be detrimental".?

there two schools of thought on this and i am of those how believe that lightweight crank pulleys do not poses the necessary dampening properties that a stock pulley/ balancer has. the closer you get to redline the more stress is being placed on the crank by the pistons and what not. in a nut shell the balancer keeps the crank from vibrating to the point where something brakes.

like i said there are some who feel that what i've just said is just not so and i respect they're stand on the issue but i have by believes and stand by them.
