Damn Evil. Drive that thing down to Sac and give me a ride. Hell, my sister live in Yuba City...that might give me a reason to come up there. How fast does your turbo motor run?

I have currently 90.5 pistons (82 stroke) in my street engine. Dyno HP is 218 and ET 12.6/109. How much HP's would increase if I change to 94mm pistons and what would happend to ET?

The 94's in themselves will not give you much more HP but will give some additional torque. The big thing with going to 94's is that you can run larger valves/ports now and do more chamber work. THATS what will give you the HP.

Well i cant really tell you how much more you might get, But i can tell you that you have more in your car then you might think.
Your mph is always a decent indication of hp. And your et is a little off compared to a car at full potential running 109. In 2000 in aspirated form still, I ripped of a 12.08 at almost 108mph. Tells me you can do some suspension and/or gearing work to get it quicker. Unless your on harder then rock street tires.
But I wouldn?t let that stop me from using the 94?s.

Max power was at 7100rpm, cr is 10.5 with copper spacers between head and cylinder. When I remove them I have 12:1, but it requires race fuel. Maybe I change the cam too. I had 87 and like to try a 89, maybe with cr 12 and 94 pistons it would work well. By the way, ET 12.6 was with with 5 years old street tyres and a HUGE wheelspin at 1. and 2. and even 3. gears. But now I have slicks in garage...

218 hp out of a 2110???? is it Turbo? Nitrous? cuz DAMN!!!! thats alot of power from a 2110 on pump gas at ANY c/r!! without a turbo, you should be around 150-180 hp--- even on race gas!! IDA's, a whole butt-load of headwork, a nasty cam and "some ungodly number:1 c/r maybe, but still very impressive. im gettin right at 310 hp w/ a T04 and a Holley 750, 8.0:1 c/r, and $1600 worth of heads-- so whatever you did, keep doin it and sell your engine specs on e-bay!!

OK, got the duct tape, JB weld, bailing wire, and a big hammer- everything should be fine.

Well... No nitro or turbo are used. I had run without fan belt and with stinger. Sound is a quite noisy (but impressive) with a Berg 1 7/8 exhaust. Heads are SF1 and carbs IDAs with 42 venturis. Rockers are Berg 1.5, lift at valve is 16.2mm!! Stock lenght con-rods are used and 200mm stock clutch plate too, with kennedy 2300 lbs pressure plate.

cool pictures, spanking the V8's

with the parts your using, i can forsee the 218 hp your putting out.

put that thing on slicks and your looking at some high 11 second passes.

although, in the pictures, your rear end looks to be squatting pretty far and changing the angle of your tires too much, maybe thats part of the problem with the street tires. and your getting into the realm of having too much hp with out chaning suspension settings. bigger torsions, adjustable shocks, bla bla bla.
good luck, when your on slicks, let us know how it runs.

Nice pan!
Mike is absolutely right about the rear wheels. Tune up that suspension and you will go a lot faster. This are some good numbers already.

I`ll raise rear suspension one spline, install "flop stop`s" under spring plates and use bus snubbers. What do you think about these non expensive modifications?

Thats a step in the right direction.
