Even if the cylinders arent arrange to take full advantage, there is better spool up just having each bank isolated to one side of the scroll. The theory is it has more velocity, and carries the engine pulses all the way to wheel. With an open flange the engine pulses get dampened. On...

Re: 4.3L LV3 (Ecotec 3 V6) Someone already did a midmount turbo on one of these. Pump gas, china VS racing turbo, 11 psi , 12 deg. timing , bone stock motor, 400whp. He stopped there for the time being cuz the fuel system was already maxed out.

Re: Turbo 3800 blazer Checking torque can be tricky. If the bolt was at 80 it might take more than 85 to get the bolt moving again because of friction. Thats why when retorqueing is done the fastener is normally backed off completely and its supposed to be a one shot pull to desired torque...

Re: Turbo 3800 blazer 40 hp is 40hp on any nitrous kit. It has nothing to do with the engine size. If you just need to get up on boost use a hobbs switch to turn the kit off . I have an 80shot setup on a 4.3 that turns off at 9 psi and runs 15 psi once it lit up. Cant even feel it shut off.

Re: Odd fire crank ignition questions. correction , looks like only 4 and 2 would fire wrong. they would be triggered 30 deg. to early. The software must delay those firing events. I noticed the odd fire setting in Megasquirt. Besides the setting I dont see any option to it. So is it...

So I was drawing up a crank trigger for an odd fire crank project I have here. EFI I discovered that 1 6 5 are the only teeth that could possibly trigger at the correct time. 4 3 2 would will never be correct because the crank angles wont allow it. Does everybody in aftermarket just use an...

Re: JHacking updates for 2013 any updates??

Re: drag slicks all corners? Never done it myself. This video shows John Shepard driving his AWD Talon with slicks on all four. http://www.youtube.com/watch?v=LiSptlw-L_U

Re: Rod strength and folklore All the load is put on the upper half of the rod during the power stroke and even in a detonation situation. So I dont see how a rod bolt upgrade would help power wise. I do know that good rod bolts are more important in higher revving motors because the...

Re: JHacking updates for 2013 sweet! Cant wait to hear the #s. That is if your gonna give them up.

Re: JHacking updates for 2013 Methanol?

Re: JHacking updates for 2013 Must be they left a bunch of stuff unfinished to allow for custom work cuz its kinda intended for max effort programs. I looked at the pics on their page. Thats a funky looking water pump pattern. WTF? Cant believe they didnt do priority main oiling...

Re: JHacking updates for 2013 Jamie, If you dont mind me asking , what was your engine combo previous to this when you ran 4.90s.

Re: Bubba's hacked up ****ery on some poor guys Typhoon A supercharger on even 5-6 psi would have netted a bunch more power and torque gain than exhaust and a retune. Just sayin.

Re: FS: Pontiac 23* heads complete, Intake with fuel rails Danen you have a PM.

Re: Smog guy pissed me off!!! What are the PPM #s you are failing on. Everyone I have seen trying to pass always had to run very low timing and very lean. AT 2500 the turbo is all ready spooling isnt it. AT this point it will be adding some fuel.

Re: Syclone for sale on Ebay (ILLINOIS) The ad states that syclones where only built one year. Is that true?

Re: 4.000 piston help!! That could be. If thats the case then they probably have some that they havent sold yet. Jump on them now.

Re: Smog guy pissed me off!!! Ya know its completely retarded that there is even a visual inspection. If the things passes the pipe test than thats all that should matter.
