your totaly right thats why direct freak made over 300HP boosted in his FB

your just an RX7club bitch

Turdbo

i kinda want to do a hmt set up...is their anyway i could set up my carbs for a blow through set up and make my own carb hat? im just curiouse

I ment big NATURALLY ASPIRATED HP group. Spend time in the engine building forum90% of the guya buid bridges and perry ports there. Rx7 club is the turbo spot. And Dude, Alex is a buddie of mine I've known him since 1999. He's using a different engine than we're talking about. He has a big dollar Cosmo 13b which has huge stock ports, and his is street ported beyond that. He has a very big dollar car. When he was running blow through he put 370 to the wheels @17psi. If you talk to him as I'm sure you naver have, his car was a bitch to drive blowing through the holley. He could never get it tuned right. Now that he's running a Haltech that put 490@17psi. So you can suck my dick! And directfreak as you know him had about 6000 posts on the club and aout 2000 on nopistons. Tell me where he prefers it. I've been building rotaries since before you had your licence. You can sure blow through a holley, but people are making higher HP numbers and have way better driveability on a weber. The problem is a Holley has to sit sideways on a rotary. Even with center hung float bowls the rear float bowl sill fills faster than the front and causes the rear to run super rich and the front to run lean. Second the holley has to have flow across all 4 chokes allways. and the way a rotary pulses and have to have devided manifolds holleys run like ----. RB modified ones make the carb merge so you can get flow across the whole carb, but it ***** up the velocity in the primanr andsecondary ports causing a shitty running car. You can just use an open hole space on any holley on a RB manifold, but it'll never run perfect. A weber has none of these probelms. Robert at Rotaryshack made 710rwhp on a blow through weber on a, are you ready? ON A 12A! Yea that's right... Enough said...

wow someone got his panties in a twist.. i didnt say ---- about 95% of that stuff yet you felt you had to come bitch about it all to prove me wrong, you obviously have no life, hurray for you!

i've done blow through setups, i never argued about anything you said, i simply gave the guy a place to gather info where someone had the setup he was talking about, and said you were wrong about NP being mainly NA power

btw the guy who had the SC setup was fluid dynamics if i remember right

good luck with your search, dont let this asshat change your mind on what you want to do because he has to have the bigger e-*****

Turdbo

im still not changing my mind...im not doing it for over all power or giant numbers..i just want to run a SC because its different and not to many people do it i want to do a set up like this

another hmt members SC build


or like this

Welp if supercharger is your goal. You need to get some maps and figure ou wha charger is coing to best fit your application. You'll need to figure out what carb your going to run, and what the max CFM of said carb is going to be and then you need to pick a charger for said application. In my research I found that a M62 was waaaaaayyyy too small. A m90 might work if you have modest power goals. By modest I mean 180 rwhp. Just look at the scoobie above he ran 2 m62's and choked up top cause the engine was pulling more air than the turbos could push. Now remember that your rotary is not a piston engine. And will out flow near every affordable supercharger above 6000 rpm. You will out flow a M90 if you're running a decent carb. If you go Whipple then you've got something that'll work great. If you want something bolt on try atkinsrotary, but know that even with theyr 9" charger on a built to ---- engine only made 210rwhp @14 psi. And the exact same engine with a turbo made 305rwhp @ 10 psi. The problem as stated before is that rotaries flow sooooo much air at high RPMS. It can be done, but noone has seen more than Dave with 210rwhp. Shoot Atkins own supercharged cars have yet to break 200whp. Most of that is cause the camden supercharger is the most ineficiant charer available. I hope you don't mind eshaft wear also.

Anubis_4_99

no the problem as stated before is you dont like him doing an SC setup and are trying your best into scareing him into a turbo

he's stated he isnt shooting for big HP, he's going for something more original on an RX

turdbo, head over to NP and hit up fluid dynamics, he'll give you the skinny on a HMS setup for the 7

Turdbo

ya around 180 to 200 is what im shooting for and with the set up im running i also want to run a IC and BOV...i'll hit him up on nopistons.com and see what he has to say...remember its only a 12a and redlines at 7grand ..its not a 13b... im trying for maybe an m90 or m112 as long as it boosts the power and makes it a little funner to drive...but racing beat it very expensive...i think im going to send bmcrace some templated and have him make me an intake flange and carb flange and TIG up my own IM, 250 bux is a little crazy when i could make 1 for 100...and i come across superchargers rather cheap 150 for an m90...so the build shouldnt be bad at all...but i wonder how clutches hold up

what about edlebrok carbs

hyper4mance2k

Edlebrock carbs are usually ------ bore and there are currently not any manifolds available for them. If it's a edlebrock square bore manifold it should fit fine on the RB manifold. Remember if you're going to be using a carb on the RB manifold that was not RB prepped you HAVE to put on a open air spacer to get it to run right. Most any square bore carb( Holley, Carter, Edlebrock) will fit on a RB manifold with a spacer.
something like that. No aftermarket carb will fit on the stock manifold with excpetion to the Sterling carb, whick is just a modded nikki, and he has yet to fully test any of his carbs in a boosted application. Sterling was tossing around the idea of supercharging on Rx7club a few years ago. There were a few 14 page arguements about it. Just search supercharger over there and you'll get pages and pages of links. If you're dead set on supercharging talk to people that have done it or have personal firends that had them. Talk to Codeblue and Codeblue2 on nopistons see what they tell you. Also talk to Sonicrat on rx7club he has had about 7 different supercharged 7's. And a 12a has the same issue as I was talking about. All rotaries had a 7k redline until 1989 S5 and up moved to 8k... Read for a few days and see what you think. That's what I did. An M90 should work that was my origional plan. But after years of research and hands on experiance with both setups I went Turbo. Superchargers are fun as hell boost nice and low in the rpms! Here's a link doing basicaly what you want to do, but it was on a s4 na car. It got locked for going way off topic, but it's a good read. http://www.rx7club.com/showthread.ph...t=supercharger
Here's another one for you. http://www.rx7club.com/search.php?searchid=2137689
And I'm not tryin to be an ***, or skew your view, just helping out a fellow rotard. I'd hate to see you spend hundreds of dollars and feel like you wasted your money.
