ok we all know the story on it. i've been seeing more posts lately regarding this and just thuoght i'd ask for my future setup. is the intake air temp really a problem if you're only boosting 6psi? btw, i live in MN where temps range from below zero to 100 deg F. i just want to know if all this hot air talk is referring to when people upgrade pullies only.

thankyou!

Sonny

It definitely does not refer to people with upgrade pullies only. Here's my car with the 6 psi pulley.



I saw it go as hight as ~205 degrees with the 6 psi pulley.

ouch. do you have troubles with knocking at those temps?

thanks

wow... i wonder if a hondata intake manifold gasket would help?

Sonny

Hondata manifold helped a little. It helped reduce heatsoak from the head, but it cannot directly cool the charge which is the problem with the JRSC.

I didn't really have a problem with detonation since I tuned the car pretty conservatively.

what was the temperature (weather) on the day of that reading? so as long as its tuned safely, you're only looking at power loss?

sushibug

not worth it. it makes like 29whp or something? pretty pathetic compared to turbos... even the cheapest kit (greddy) owns it. you cant beat turbos.. the spooling sound, the bov, the mad rush of hp/torque...

not true. those 9 psi jackson gsrs are SICK. hp and torque throughout the whole powerband. and the hp you get is application and pulley specific.

i've never seen one hit 300hp. theres like a post here everyday about a turbo car hitting that. they suck man, heat soak is a real big deal. on hot days it sucks, when you drive another person you are noticably slower, blah blah. water injection kit is worthless compared to an intercooler.

they have their moments but you will regret not going turbo. reminds me of that jrsc guy who had an intercooler setup on it.. which he switched out later. such a waste of money. theres a guy at the local track.. went every week had a sohc civic jrsc w/ upgraded pulley blah blah, ran 9.2 in the 1/8th... he spent months working on that. he went turbo and got 8.9 on his first run.

edit: dont forget.. for SCs it takes power to make power.. and because its belt driven it can come loose (which i hear occurs a lot.) only downside to turbos is the lag, but personally i like it.. cuz when it hits.. it hits hard since yer chuggin. then again u can just get a small turbo. either way.. SCs =

Although the Jackson kit has its drawbacks, for some, it is a good choice. I did it and I have no regrets. That kit taught me a lot about boost and engine management. My next car is a turbo'd car, but the simplicity of the Jackson kit (as well as being smog legal in California) makes it an attractive option for most people.

With the 8 psi pulley, my gains were about 70 whp (137 whp stock vs 215 whp @ 8psi).

It made the oh-so-gutless (below 4000 rpm) B16A2 a very tractable and fun engine. I think the JRSC is a good kit for people wanting a respectable power increase, simplicity, good instructions, legality, and linear power delivery.

Sure, you can get more with a turbo....but...different strokes for different folks.

My 2 cents...

Sonny

damn Sonny thats some hot air....

just fyi greddy turbo 6psi seems like more power than JRSC 6psi.

but with the stock exhaust i must say they felt about the same.

turbo is getting the nod from me after trying out both systems. but you're absolutely correct i learned SO MUCH from installing (and removing) the JRSC...and there are pluses and minuses of each.

hmmm i wasnt planning on getting into the sc/turbo debate but i wont complain since i feel like i'm still undecided. if you didnt notice my sig, i have a b16 crx that i want to go FI with. i did my motor swap myself so i'm fairly mechanically inclined, however, i've have NO experience with FI. from all of the reading i've done, it seems like there's a lot more involved to install a turbo. ok, big deal, i suppose i could handle it. the only thing is that i dont really hear too much about turbo b series crx's simply because of the clearance issues involved.

another thing is i'm not going to rebuild any internals when i go FI. i've heard its not necessary to run 6psi sc'd, but should i build up my motor if i ever went 8 psi in the future? also, say i went for a turbo kit, if i boost 6-8 psi, would i need to ungrade any internals?

this brings me to another point, this is my daily driver, so i need reliability and also the reassurance that it will last a long time. not to mention it would be nice to have my torqueless power band increased with a SC.

so all in all i guess the subject of this post has changed, but from what i mentioned above, i'd appreciate some input as to if you agree a SC would be right for me instead of turbo. if you still think turbo, give me some more good reasons why it'd be right for me.

thanks

I build alot of supercharged cars, If you want good top end , a turbo is the way to go , If you want power every time you hit the gas , you want a supercharger. I wish I had the dyno to a friends B16A in his CRX , The motor is competely stock , it runs 10psi and makes 231HP and 155TQ , I know a turbo will make 280 but this makes 148TQ @ 3000rpm. It has been running everyday for two years and never thown a belt.
I'm not saying one is better than the other, but there is more to the supercharger than most think.
My car has an LSVtec is supercharged , it makes 267@ 198TQ, it make 190Tq @ 3000rpm, it's running 7psi with an expermental intercooler I have designed, the only down side to this car is traction. The car pulls instanly the gas is hit with no lag or hesitation. I will try to post some dyno's later.

anymore opinions? thanks

I have a '99 GSR with the Jackson at 9psi and I love it. I will be getting my Hondata S200 soon and then I'll take it to the track. There are a lot of guys on Hostboard that run mid twelves consistantly at the kind of boost I'm running and of course they drive them everyday. My buddy I work with has one on his '99 SI and has not had ANY trouble with it for 50,000 miles. Sure your not going to have 350 HP, but, it will still be fast enough to hang with most cars on the road, if not beat them.

I wanted to go with the JRSC originally but after I learned more about turbos, they dont sound appealing at all. Turbos have gobs for tuning potential.

ok thanks guys
