Im sure I will strap it on a dyno and compare it with Z1 sometime to get a better relative scale.
Its general knowledge that it is around 10-12%

there really is no comparison that can be drawn from one to another...it is all relative to the exact dynos being compared (not the types of dyno's, but the exact dynos). Some DD to DJ will be 11-12%, some will be higher, some will be lower. It's all relative to how those 2 dyno's are setup in the first place

agreed 100%

I put down 405 on a dyno pack and a 360 DDynamics TTZ crushed me... although he also had 100ft lbs of torque more also....lol

lol

+1 then... +1 again.

That's why it'd make more sense to have a dyno day or something.

I'm looking forward to seeing Jenvey's airbox design. Then maybe we can see these ITB's used in an FI application.

The New airbox design will be on display at the PRI show in Orlando. The kits will be available a couple of weeks after the show. Although the ITB's can be used for FI the airbox was not made with this in mind and are not made to withstand boost. You would have to make a custom box for you application. I believe any competent shop can fab up an aluminum airbox for boost, and there are several that show their ability on here everyday.

would you be able to reach 350whp (DJ) without the help of ITB?

Im looking to do an N/A stroker in the future but im not so sure i want to go with ITB

It maybe possible but I'm not aware of anyone who has done so yet.

The answer is how much money do you have saved up and how far are you willing to go?

What you need other than the stroker without the ITBs would be very aggressive cams (cosworth maybe) and larger valves. We didn't do the valves which would've netted us a good amount of hp. Ultimately if you push the compression up to race spec you could attain 350whp without ITBs.

Cosworth just built a 360whp/290wtq DE for the syntec topshop challenge. Give them a ring and ask them how much it'll cost to duplicate.

Im pretty sure you can make this power n/a with a 4.3 high compression stroker, a decent intake manifold, cams and head work.

That also depends if the DD is an uncorrected number or corrected or not. If the DD is corrected to simulate a DJ numbers you will be way off if you add 10 to 12% more to the already corrected number.

True DD are not corrected. And yes I am aware of this as simple math is not difficult.

I just mentioned that because some people on this board have claimed a DD dyno corrected to represent a DJ as a uncorrected DD dyno.

hmm this is just for street use/93 octane, so race spec is out of the question.

do you have any vids yet? I'd like to see how this car sounds
