80X91
sam, I plan on testing a 2270 engine built to "Kit" specs, like yours to see how much boost it takes to make things start to compromise..
The only killer is the KB pistons supposedly do not like boost- I guess we'll see if I can defy the rules set by the KB fatory and make it work anyway!

Would be interesting. Didn't Evil Ed use KB pistons on his 1.7 turbo build?

I think they were stock. KB doesn't make a 90mm piston.
I used the 91mm size because I LOVE small bored Turbo engines and also so I could do some testing with a stock 1700 cylinder bored to 91mm from 90 against a set of Nickies that Charles and I developed especially for a Turbo..
Its all about being able to crank up the boost- engine size doesn't matter- just strength.

Sweet! with that stroke it should be a stump puller before the turbo spools.
Question, single TB or dual TB for the EFI Jake?

Dual T/B...
This is a dual ball bearing Turbo- it will spool right off idle.

The stock pistons can take beatings... My car pinged VERY bad on the dyno, I've never heared a car that pinged so hard, sounded like someone was banging with a hammer on the blcok

Jake,
Any chance this set-up will fit under the bonnet of an early Beetle?
Thanks, Dave

Not an issue as I am running a set of JE's
Would make a really nice upgrade for the future... Will have to start saving the pennies.
Cheers,

I'm already doing that.

the price on that kit seems like a deal, considering all that is included. The turbo part of it isn't that much. I'm thinking those of us that already have 150HP but maybe do not have the optimum combo for the turbo, or the internal strength, can still have a hell of a ride with conservative boost.

Jake, i guess you see me coming...
That would be a blast on a super hero wouldn't it?

One thing I was forgetting was CR with boost. I'm not sure an engine like Scamcats, Ephry's, mine, etc could take enough boost to make it worth while. Jake says he will be testing it on a 2270 built to kit specs, so maybe I'm wrong. It will be interseting to see.

Good point Ron. I guess at worse case scenario we can always use some water/alcohol injection to cool the charge.
With our 2270s the thing is head sealing even before we can worry about too much boost heating things up. I am even willing to step down to a 94mm piston/cylinder if it will help control head leaks(specially if using some nickies, then again, maybe some thicker nickies may help keep the 96mm bore under check with boost)

Only time will tell..
The fabricator finished my dyno Turbo last week, so it's just a matter of time before the seriousness starts!
