95blazer Posted November 24, 2004 Report Share Posted November 24, 2004 (edited) Well I just completed my mods and decided to let Alba dial it in for me. When I took it there I knew it was jetted way rich just to be safe. My mods are as follows: Pro circuit pipes, pro-flow kit w/ K&N, airbox lid removed, V-force delta 2 reeds, head milled for race gas, timing advanced 4 degrees, lightened flywheel, running VP C-12 race fuel. I am very happy with the results and will test it out on Thursday at Glamis!!! Let me know what you think of these numbers #1- 370 mains, stk needle 4th clip, 30 pilot, air screw 2 turns out---This gave me a max of 46.27 hp at 8200rpms. This also gave me 39,45hp at 9300 rpms. #2 300 mains, Alba needle 4th clip, 30 pilot, air screw 1 turn out---This gave me a max of 49.29 hp at 9300 rpms Derek Edited November 24, 2004 by 95blazer Quote Link to comment Share on other sites More sharing options...

fixitrod Posted November 24, 2004 Report Share Posted November 24, 2004 looks like you gained some bottom and a powerband from hell at the top. I bet it pulls a lot harder now on top. Quote Link to comment Share on other sites More sharing options...
Banchetta Posted November 25, 2004 Report Share Posted November 25, 2004 thats a pretty big jump in jet size, Did you try other sizes as well? Did you pin it down to one size being the best?? I bet you have another few more ponies in there if they didn't try other sizes....49 hp isn't bad, but I think you can get more than that w/ jetting.

Schizo Posted November 25, 2004 Report Share Posted November 25, 2004 (edited) Well I just completed my mods and decided to let Alba dial it in for me. 284570[/snapback] Keep in mind that when on the dyno they are only looking for HP#'s and that doesnt mean that it will be jetted right on. When i had mine tuned on the dyno it ran like dog shit out in the field and all the jetting that was done on the dyno i changed except for the pilots. So basically just because it is "tuned' on the dyno doesnt mean that its jetted perfect or runs perfect.

RNBRAD Posted November 25, 2004 Report Share Posted November 25, 2004 What about torque results? HP is so over rated, ya know what they say, HP sellls engines, torque wins races. Quote Link to comment Share on other sites More sharing options...

superchicken Posted November 26, 2004 Report Share Posted November 26, 2004 my question is why between 7000rpm and 8500rpm there was a few dips in hp?could it be that it bogged a bit because of an over rich main? a 370 main seems kinda rich to me but i dont know his elevation.

Redlined Posted November 26, 2004 Report Share Posted November 26, 2004 superchicken, I think the one with the dip is the 300 Main. Could that dip be associated to the needle? Quote Link to comment Share on other sites More sharing options...
superchicken Posted November 26, 2004 Report Share Posted November 26, 2004 after a closer look i admit i was wrong. would a lean main cause the stumble? Quote Link to comment Share on other sites More sharing options...
Wallynut Posted November 27, 2004 Report Share Posted November 27, 2004 This maybe a dumb question, but someone who's never done the dyno might wonder. Don't shops that run dyno's have some way of testing/analyzing the exhaust gas's to determine if the fuel/air mix is where it needs to be throughout the rpm range?

locogato11283 Posted November 27, 2004 Report Share Posted November 27, 2004 i wouldnt trust a shops jetting on a dyno. arent they jetting in favorable conditions when they run them on the dyno? what if the temp is 80 degrees in the dyno booth and its 55 outside? your jetting wont be even close to right. jetting on the dyno to see how much hp you can get is fine but i would pay close attention to it after it leaves the shop. you wouldnt wanna burn up a top end becasue its too lean. you feel me?

InFlames Posted November 28, 2004 Report Share Posted November 28, 2004 I think some people figured out on planet sand that the high rpm dip had to do with the stock ignition its not confirmed yet though. Quote Link to comment Share on other sites More sharing options...
