667whp/555tq dynojet

GTX3076r .78 twin scroll @ 30psi running 70% ethanol

Pretty happy with the results, car ran 10.7 1/4 mile on Friday hopefully can get it down to 10.4 or so at this power

thats excellent. i'd love to see a dyno run! is your engine just sleeved and bored out or stroked also?

Thanks man.

I will post up the dyno sheet tonight. The block is sleeved, 87mm bore with 91mm stroker crank.

At this power before with a non sleeved block the cylinders ovaled

dang. i'll have to be careful. I'm running 87mm pistons (CP VE pistons), no sleeves, but I'm only aiming for just over 500whp on pump gas.

There are plenty of people deep into the 600's on factory sleeves, albeit I'm unsure of their bore size. You should be fine.

When this happened to me Mazworx informed us that they have seen this happen with factory sleeves before.

I would assume stock bore or .5mm over is safer but with a 87mm bore the chance of failure is there.

Like you said he should be fine at that power level but if you plan to crank it up you may run into issues.

yeah I have a top-tier engine builder and a very reputable machine shop so I should be good! gonna run 110 octane any time a really crank up the boost too (track/drift use)
