just like i stated in the title. i always see turbo cars making 500 + whp and was wondering if there are any supercharged ones making about 500whp.. im planning on building my own supercharged car. something along the lines of a b16 head with a 2.0ltr bored gsr bottom end.thats as far as i know right now. compression ratios, type of supercharger etc etc are all unknown right now.. im just curious to know what kind of power these supercharged motors are making.. just doing some homework.. any help is greatly appreciated

 

i can relate to what your sayin.. but i just cant trust a 4cyl crank...but if u can make power from a supercharged honda i think that'd b pretty cool, i luv boost but id like to see/feel wat a low end powered honda would feel like haha..goodluck

 

i wanna see

 

I don't know enough about SC's to really say much, but from what I do know, you'd need a blower sized for a typical V8, otherwise you'd have to over spin the blower to the point of destruction. At that point, such a large blower would create drivability problems, and probably put a huge load on the motor just off idle. I'm sure you could find some 500whp centripetal blown hondas, but those would probably have a worse power curve than a big turbo (due to their nature).

As for the 4cyl crank deal... Inline motors are some of the toughest designs. Much less problems lb for lb versus a V. The huge inline-6 designs from the 50's and whatnot were used for a very long time, mainly because they were bullet proof. There's a reason you see more 700whp hondas and 1200whp supras than 300zx's.

Me too.

 

Id love to see that too. I saw an eg at the local drag strip a few months back that had a supercharger AND a turbo on it. That may be a common practice but I had never seen it before. If you think about it, it makes since though,... The supercharger would take care of the bottom end power as well as all but eliminate the lag. Only thing that concerns me is how would the spercharger NOT hinder the turbo? It seems like since the supercharger is gear driven it would also be gear limited in flow. I dont know a heck of a lot about them though. Have you or anyone else heard about or seen this done?

 

ive seen that setup once in a magazine..couldnt believe it was real. i wonder how that motor runs n wat kind of numbers it would pull...

 

thanks for the answer.. i guess ill just have to do some more homework and then weigh out the pros and cons and see if this a task ill want to take or just go turbo like every other fast honda

 

honestly youll be hell bent to see very many supercharged hondas even making 300whp on charger alone. if you want 500whp on a charger get a Cobra and put an ehxuast and pulley on it. have a nice day

 

I dont know of any 500hp supercharged setups. I had a Jackson Racing setup on my b16. I think I only made in the range of 220hp, but it started at like 1300rpm and that was nice. I can tell you though that the pull is much harder on a turbo set up like I have now. But the low end of the supercharger is very nice... however you need to be more carefull of the temps with some supercharger setups like a roots one. Plus they usually like more fuel.

yeah the problem with the superchargers for hondas is they dont flow awhole lot and when u start spinning them too high rpms you just end up with heat and possibly damage overtime to the S/C. 300whp is about the max youll reach with a JRSC type supercharger thats with extensive modding too the head. Endyn has some superchargers that r modified for more power check em out. http://www.theoldone.com

 

there is a guy on here who did a real serious "twin charger" setup, where the sc spools the turbo, it was very complex. He had it set to ween out the sc as the turbo spooled making it a true twin charged setup, not just a turbo slapped on a sc.

forget who did it, im sure hell post up here soon

If im not mistaken the car made 300 something whp, with a pretty crazy power curve

 

This is the most I've heard of with the JRSC I think, and it is definitely possible to push a setup like that farther too. Imagine that kind of supercharged power IN A CRX!! I mean, turbo is turbo and everyone knows that your power potential is practically limitless, but with a supercharger it's like having an all motor car on crack. No lag whatsoever with insant throttle response and massive low-end torque. People always go crazy about the torque on NA b20vtec's right? Okay, so slap a freaking supercharger on top of that and <U>wow</U>. Two-hundred and twelve foot pounds of torque in a crx (or any Honda) is no joke. Again, people make that much torque and more with turbo all the time but this is different. It would basically feel like an all motor car that has 300hp and 200tq and that is nuts. I'm sorry for going on about this but it's like one of my dream setups because it would just be loads of fun.

RCMcDaniels, car made over 300whp and had the power curve of a baby's bottom. The setup really wasn't all that complex, all he did was open up the plenum in the supercharger so that when the turbo came to full boost (or whatever PSI his hobbs switch was at) the turbo would be the only thing pressurizing the plenum, thus bypassing the SC.

500whp is not happening on our small Honda engines with a roots style blower. I personally know someone who has a fully built B16 who pushed out over 550whp using a procharger setup (centrifugal) but it took him a little over $20K to complete.

Most basic roots chargers are making 160s with Dseries, 200-220 with Bseries. A B20 that used to make a tad over 300whp and sc4dr used to have a B18C5 making about the same. Both highly modified, I don't know for sure but I think sc4dr barely broke his car into the 12s, can't remember for sure. Hopefully he'll chime in, but I do remember that he would launch in 2nd gear because 1st gear was utterly useless.

Think that's about it.

Oh forgot, so far every single supercharged K20 I've heard of has been over 300whp and something around 250wtq. Being as you practically have to drop the engine to see the exhaust manifold on the new K20 Si's... I could see this becoming a favorite setup for many people later on.

 

Actually the dual-charged setup made 350 WHP. It could have made more, but I was about to sell that B16 long block and didn't want to beat on it. It's on a friend of mine's car now, we just built him a very nice sleeved LS/VTEC motor that should put up some pretty good numbers. I think he goes to the dyno with it on the 28th.

My current supercharged B22 made a hair over 300 WHP at 8 PSI of boost, but I hydro-locked it in a flood before I got it all together right. It's going back together now with new custom pistons plus a few other goodies and will be making 10 PSI of intercooled boost from a modified blower. I'm looking for 325-350.

The main problem is that the biggest positive displacement blower for a B-series is the Eaton M62, which won't push enough air to make big power. Add to that the blowers for Honda motors need to spin CCW, and most other blowers (and all Lysholm blowers) spin CW. I'm in the process of getting an Eaton M90 modified to spin CCW. It's 50% bigger than an M62 and I think that a properly modified M90 could make 450-500 WHP on a well built/tuned motor.

 

The most i made with a jrsc was 304 whp and 250 wtq. it was an Endyn modded M62 on a 2.1L B18c1. It was not intercooled like rmcdaniels, so he should make 325 realistically. There is no way you'll ever get close to 500 hp with an eaton blower...it's just not going to happen, so i sold it TURBO!!!!!!!!!!!!!!!!!!

lol. I know people love the instant response of blowers, but seriously... If a serious non-intercooled JRSC setup does a tad over 300whp, and a 60 trim straight T3 can do close to the same numbers on a 1.6L, and has almost no lag...there's not much of a debate. You could go with a 50trim T3 non-intercooled and get the same numbers as a typical JRSC setup (granted with a bit more boost) - both whp *and* IAT numbers. Same for that turbo & SC with an intercooler - again, not much different, except the air-water IC for the JRSC will cost an easy 5x more than a simple fmic & piping for the turbo.

IMO the only <U>good thing about the current JRSC on a D or B series motor is that you really don't have to modify much</U> to get it on, and can keep your current header/exhaust as-is. But if you can cut & weld to some extent, the choice is a no-brainer.

(not hatin on blowers - they are nice items - I just don't prefer them.)

 

I love it when people who obviously haven't had a SC tell everyone about the pros/cons of the two setups.

 

Roots SC's will have problems producing that power because of IATs and blower size. The size needed to make the power is not excessible to hondas as rmc has mentioned. It is also relatively costly to keep IATs in check due to the fact roots SC's do A LOT of work on the air in order to get it moving/compressed. Far more than a compressor does. Also reaching a number like 500hp is more difficult because generally speaking roots SC's are designed for lower rpm response and die off more in the top end. As we know, hondas make their HP in the top end, so it makes it extremely difficult to accompish such a task with a roots SC. If you just wanted to make 300-350 ftlbs, I think that goal would be more feasible.

Centifigual SC's are what most serious dragsters use in their cars. The problem with those on a honda is, with the larger compressors, you will need to really spin the engine pretty damn high to get a usable powerband, higher than on a turbo engine. As most know, RPMs really take their toll on engines.

Honestly, using a ball-bearing GT30r turbo will be a lot cheaper than using a SC. It will fall somewhere in between a roots and centrifigual setup. Sure the throttle response won't be as great, but it will be far less expensive and much easier to make the power.

Are you going by experience here or what everyone else says, because mine oddly enough continues to make power well beyond my 7K limit.

 

The myth of an eaton blower dying off up top is crazy. the powerband is like a fat all motor setup. Depending on cam and head package eatons will keep climbing well past redline.

The fact of the matter is that if your looking for 200-300 hp with crazy torque down low and a very dependable setup a jrsc is a good choice. If you want more like I do, Turbo is the only way to fly
