Re: Hemi vs Chevy wager...

Keep it simple. Add a On3 94mm or 107mm turbo for $1000-1200. Turn boost controller to 11

Re: "Hedifolds" the good, bad, and ugly?

Economics. That is all. Will the head warp on the ex side? Yes. Within warranty? Prolly not.

Re: Bigger lifter bores gen 1 sbc

What is the application? Max rpm and what valvespring pressures do you intend to use? Big lifter bores are not low hanging fruit in hp per $ with SFT until you are pushing the envelope a bit.

Re: Timing tape- printable....

I do understand this is the right way to do it. I am curious tho, how many folks have seen errors with a decent dial-back timing light and tdc mark.

Re: Coating Air cooled pistons

To the original poster: What approximate wheel hp range are you shooting for with the air cooled suzuki?

Re: Coating Air cooled pistons

Back to the original poster's GS1100. Being air cooled, piston to bore clearance at your average riding or racing conditions/temp will be #1 priority for making hp and having the mill live. Magic coatings, oil squirters, water injection are distant 2nds if you have sufficient octane.

Re: Coating Air cooled pistons

Saw the idea years ago. A corvair land speed racer was injecting water into the cooling fan to help keep head temps under control. Why isn't this captain obvious idea more widespread with aircooled guys?

Re: It runs faster on low octane fuel?

On my own all motor honda drag car. Was perfectly safe to make max hp on 93 with maxed ignition timing. Switched to 110 leaded fuel in anticipation of hitting it with nitrous. Required 3 more degrees of ignition timing to make the same hp on the dyno on the motor.

Re: Points ignition? Any advantages?

In terms of of maximum power output, if the points distributor is capable of supporting the rpm and cylinder pressure without a misfire, and no mechanically induced timing changes, little will be gained from anything different.

Re: Turbo Back Pressure

Getting the exhaust pressure down leads to a more broad and forgiving tune window. Fewer melted piston ashtrays.

Re: More budget SBC stuff

Again, GaryC, the proper sbc intake manifold for the average joe hotrodder making the highest average hp/tq in the 2800-6000 range (350-425hp ) is not on the market.
