oh dDub, you're so ignorant! that's not a supercharger, it's a giant smog pump supercharger kit! duh! smog pump superchargers pwn j0o!!!$%W!E

 

Haha

Anyways, the overspin of that charger was a pulley problem that Nelson provided a fix for and a simple change of the pulley created no overspin problems.

The guy that was selling this ran a walbro fuel pump, 4x550cc injectors, 9lbs of boost, fpr, and a streetport. Not too shabby, I wish I could find some dynos of someone with this kit, though, would've been interesting to compare.

 

i want to do a custom Vortech setup. i don't know what lines i need to run as far as oil and/or water cooling, though. i don't know much about turbos and less about s-chargers. i mainly want to do the s-charger so i dont have to tap the oil pan and front cover. if i'd have to do this on a s-charger, forget it! i dont think i'll have the car long enough to justify the work.

 

You don't HAVE to tap the front cover for oil on the turbo job. My plan is to use the racing beat oil pedistal adapter used for gauges and run oil feed off of that to the turbo, then tap the oil pan for oil return, makes it a tad simpler. You can also buy a TII front cover to use since it is pre-tapped and ready for oil feed. Plus I already have a second oil pan sitting here waiting to get the work done to it. I plan to do everything I can before ever starting the actual install on the car, that way I'll just have to put the pieces together mostly.

 

Only problem with that is the oil pan generally is filled with oil, so the drain backs up because there's not a whole lot of force behind it. Now... As for 'torque' and 'hp'. Kahrens car makes about the same HP (stock ports, stock exh manifold), the only difference was the 20ft-lb increase accross the board. Gotta love custom intake manifolds. And you have to remember, this car isn't 'exactly' stock, and neither was codeblue's, and it still isn't much over the 200rwhp range.

 

yea, i've heard of running different sources for the turbo, but the oil pan was my main concern. that job just doesn't sound fun. if only the oil pan was easier to get to. maybe i'm exaggerating the whole ordeal? my engine was just out and i dont wanna have to go through too much work all over again.

 

actually i wouldn't mind taking a look at this kit in person, if you are ever up near Yuba city/Marysville let me know or if i am around town in Sac i could swing by. i haven't seen a Scharged FC yet so it would be something to see.

 

The oil pan is a big deal, but just make sure you have some acetone and a good set of ratcheting box-ends laying around to make it easier. Took me about 4 hours to get it off, drill, then reseal and stick the pan back on.

 

dont you have to drop the crossmember (sub-frame; whatever that part's called) ? also, my oil pan was soda blasted and painted with some sparkly weird paint (kinda rough; i guess acetone may still work). i'm kinda curious what a big Vortech Supercharger, custom intake manifold and Haltech would do for an S5 N/A. wish i knew first hand.

 

It wouldn't be too bad, but not the greatest either. Their efficiency is still not as good as a turbo, now, a twin screw setup has much better efficiency (and is very capable), I've personally helped build this setup using a whipple 2300 (i commonly think it's a 2200 for some reason, so if you saw in my other thread the mistake, you understand now), which made 348rwhp on a ported s5 6port block.

 

i was more looking for simplicity. 300whp would be great, especially if the torque curve was broad (though i don't know how much broader a centrifugal supercharger's curve would be than a turbo's if any). i would like to surpass the 348 you helped someone else make, but that's more me being greedy and competetive.
i don't want to sit and ask questions i could find answers to, especially in someone else's thread. mainly, i'm looking for a more simple install than a turbo, but with a supercharger that makes more power than a stock turbo could (efficiently).

 

i know this is a little off topic and sorry to thread jack but a local shop around here just ran a 13.1 in a civic with only a bolt on pro charger kit. Has anyone ever tried a centrifical chrager on a rx-7? it would be very easy to make braketa and mount especially where the ac condesor was and also would allow for a frount mount intercooler. The civic ran the 13.1 on 9 psi. procharger offers a universal sport compact kit that could be fairly easily fit to the rx-7

 

i would wanna guess the civic had an engine swap as earlier (lighter) civics had dinky engines (the 92-95 SI hatch made a whopping 125hp) and later (heavier) civics never had much of an engine to brag about either (99 SI had 160).
either way, its been done. Nelson made a kit years ago for RX7s; in fact, a quarter page up it SHOWS the Nelson centrifugal supercharger on an RX7. so yes, centrifugal superchargers have not only been used on rx7s, but there's even been at least one kit made for them.

 

yeah sorry somehow i missed that page, but that kit is not intercooled, and the civic was and otherwise stock si mod were a follows, 2000 civic si, lowered, procharger supercharger kit with frount mount intercooler, dc sports header, exhaust, and fuel controlled through a vafc(that i installed, ) and a fuel presure regulator. best run was 13.1 at 107mph with slicks and a 1.8 60ft. according to procharger this is the best time for the kit with 9psi. the block was just pulled to be bored and stroked to 1.9, forged pistons and rods, ported head, and 12 psi pulley when back together hopping for low 11s with nitrous

 

cool.
just to chime in here, I'm sure the civicv setup 'charger is ok to run to 8500 rpm all day long since that is right around the '99 civic redline.

heh heh, all this work and you guys still dont get "monster" power.... I guess that makes me much happier since I went with an all aluminum LS1 V8 setup... it was easy peasy as far as building a import into a 350 hp autox'er.

 

350hp isn't quite "monsterous" either. getting 400 to the wheels out of a 2-rotor isn't exactly hard to do, either. also, 400 to the wheels on slicks should be mid-11s. why's the LS1 (or any non rotary) need to be brought up here? this is the 2nd gen (rx7) tech section. talk about your ls1 rx7 autox'er at the ls1 forum or in the other engine forum of this site.
and for what it's worth, 350whp is easy-peasy from a turbo rx7, too. we're talking about superchargers and which ones will or may work, not aluminum ls1s.
