Re: Yeah, its gonna fit....and make 22 plus psi
Bypass will end up being a restriction at some point if he goes the route of bypassing the blower once the turbo is spooled.
The blower in series with the turbo does not act like a restriction, no. The blower compresses the air further, and at a geometric rate to boot = hot charge and boost spiking. No restriction there. Mean Gringo Bob had a MCU setup to cycle a bypass to maintain 2:1 exhaust to manifold pressure in his twincharged flathead Mustang, don't think the car is completed but the idea was sound (he cited a grip of literature) and I believe was how the old Lancia rally cars were set up.
Given the fragile transmissions and expensive replacement options for those cars, if he's just shooting for a broad torquey powerband with great driveability and modest power he'll have that, so it's really a moot point. Since he's already done more in a few weeks than most of you have accomplished in the last two years, I respectfully suggest you take your boyfriend's fist out of your *** and stuff it in your mouth if you don't have any experience, engineering insights, or real world physics to offer the guy in place of the "I've never done it, never seen it done, and couldn't pass an introductory college physics exam without taking the course first and working at it, but the blower will act like a restriction" noise.
Cliff notes:
- No, no, no.
- STFU and let the guy do something, since you aren't.

I love you, Leroy, make no mistake. You weren't the only one starting the Honda-tech bandwagon of jumping on this guy - even if you didn't realise that's what it was becoming - and I'm sorry if you feel I singled you out.
Short of McDaniels, I don't know of anyone with a completed twincharger setup, and I'm curious to see where this guy goes with his. Sorry if I was a dick.

Kiss and make up :P
Sure, the twincharging is going to appear pointless to most of us because "just crank up the boost on the turbo" is the answer. Maybe this guy wants to do something different... I can't help but think of Whitey twin turbocharging his civic. People probably told him it was stupid, inefficient, gay, and to just slap one larger turbo on there and call it a day. It's called originality, people. Whitey went through with it and made it work. He'll admit himself it was a redundant setup, but kudos to him for not only THINKING differently, but then actually doing it and getting the job done! I say if this guy wants to twin charge his car we should be behind him 100%. I thought HMT was supposed to be a crowd of people not following the usual "omg greddy" crowd and doing our own thing.
Good luck with the project man. Looks great.

Re: Yeah, its gonna fit....and make 22 plus psi
Did this this morning.... Made the uppipe.
Parts......
Used an existing manifold flange and pipe, welding it to the extra intercooler pipe I had
The turbo flange is 2.75 opening and I had to get there from a 2" pipe, so I bought two reducers and welding them in and up!
And the finished product.
Cost me $10 for the two reducers and the flange.
Next is the downpipe and 3" exhaust. I am probably going external wastegate, if the Audi 5000 wastegate I got an EBAY is any good.

The compressor wheels measure out to be the equivilent of a gt30.
