jackson racing on a d15b

[KuehnD15B]

im savin up for a superchager i got stock d15b with 4-2-1 header and custom 2" pipes. what would be a save amount of boost. can u run a intercooler with a superchager ?

[Dibble]

My friend has a b7 with a JRC. It runs 14s. He's a road racer, not a drag racer.

yes you can run an intercooler with a supercharger http://auto.howstuffworks.com/supercharger.htm its near the bottom

That won't work on a JRSC. I think there is an "aftercooler" modification that can be done to the JRSC but unless you are running BIG boost its not needed. The JRSC runs about 6lbs as-is but can be bumped up with a pulley change.

d15b=regular d16 rods.

can run any amount of boost a z6 can without a problem at all.

also d15= small mains like a reg 1.5

oh well i didnt know there was a different setup for the jrs, but i was just answering about the intercooler with supercharger question in general.

[vtecdevil]

with the supercharger which is install instead of the throtle body u cant add an intercooler. while if u hv some other type of supercharger u can

That is true unless you're willing to modify the JRSC. Like these people do...

Water/methanol injection is also an alternative to reduce cylinder temps.

Until recently I was running the same setup with a 4-1 header. On that motor you can hit 7psi before having to worry about temp issues. But, that's pretty common among the d-series motors. The JRSC for the D-series isn't nearly as efficient as the latest K-series which can hit 12psi before extra cooling is required.

You can use a small shot of nitrous to cool the intake charge.

[spoonfed]

You can use a small shot of nitrous to cool the intake charge.

Yeah, but anything over 7psi and you'd be pumping nitrous regularly. That'd get expensive versus water/methanol injection.

You would use it only while racing. Not all the tme.

[Dibble]

You could also use water.

[spoonfed]

Then what's the point of cooling the air charge? You'd need it daily just to drive the thing. The jackson hits max boost at 3600rpm. I have too much of a lead foot perhaps.

I have a jrc but will i need to modify my bottom end?

[vtecduck]

I have a jrc but will i need to modify my bottom end?

no, you'll be fine running it on there. I ran the boost upgrade on my stock bottom end with 180,000+ miles on it with no problems

[bluecivic101]

^^ how much can a dseries jrsc be had for these days?

[Bizzar]

^^ how much can a dseries jrsc be had for these days?

More than it cost to turbo it and get lesser results ^_-

A fair price for a used "complete" kit is around $700. It may be possible to locate a new kit stashed away somewhere, but they haven't been produced for a couple years.

throttle body? You mean intake manifold right?

[spoonfed]

throttle body? You mean intake manifold right?

That's correct. The throttle body stays.

[SOHCinWA]

That jrsc should make that little d15 scream. Actually Oscar has a new design for the newer civics now that is pretty impressive. His new headers are seriously crazy too.

I ran a JRSC on a stock D15B7 for about a year and a half. This was back in the day when it just ran off an FMU. I ran 4 psi with no tunning, the timing advanced like 2 degrees, and with a FPR. I got bored one day and got a custom pulley to run 11psi. I was in an especially self destructive mood and advanced the timing all the way, at 11psi and it ran for about 3 months before a rod shattered and shot out of the block in 3 different spots. I got a total of about 55,000 miles out of the kit before I blew it up.

To summarize, i think pretty much any SOHC is good for, at most, 8 psi with a good tune. Water injection is annoying and it has to be filled frequently, I had one for a little bit. Just tune it...

[SOHCinWA]

4psi. I thought that theirs had a pulley for 7 psi?? Am I wrong? I know that had a crx Si at their Texas store that ran a 12psi pulley with upgraded fuel management and it ran a high 10 in the 1/4. He is a real cool guy to talk to. He is in Corona,CA now. Jacksonracing.com He might be able to tell you a few things if he's not too busy building moto GP headers.

I bought a used kit that was intended for a D16, and I had a D15. The crank pullies are different sizes so it made 2 psi less than intended. It was still decently quick. With no other mods at all, i was running high 15's at 88mph in a full interior DX with ac still. No other bolt ons....at all. At 11 psi, i have no idea what it was running.

[SOHCinWA]

I would love to have one for a project motor. Want to build a daily driver D15 motor for my 88 Shuttle. Who would expect that to be quick??lol

Too summarize my setup is at 10 psi runs fine and has a good tune only a fool would run that much with a JRSC and no tune.

No, not a fool, but thanks for the attempt to randomly insult me.

It was pretty intentional and I was trying to blow the motor, as stated. Also, with the "wonderful" eaton design, there isn't much need to boost past about 8-9 psi because it just turns into a heater. :lol:

[PianoMan]

Kuehn, you probably know that the JRSC comes stock at 6psi of boost. The stock D16Z6 block can handle up to "arounds" 200whp, but I'm not sure how much boost that corresponds to.

Can't intercool, unless you go the custom route that spoonfed suggested (wow - didn't even know that existed. Rep for ya :TU: )

You'll love the JRSC kit, unless you're looking for ultimate power. I like it because it bolts on and runs just fine with it's stock fuel management (though I'm thinking an upgrade), and the engine feels like a whole different beast at the low rpms (I seldom rev above 5-6 rpm, believe it or not). Once I get an upgraded ECU and a tune, I may spend more time up there. :thehump:

Nah you did that on your own.
If you can find a relativly cheap kit I say go for it. Make sure the rotor coating is in good shape. If not places like Magnusson and endyn can help you out with that. To really take advantage of the blower you are going to have to tune it properly as it is a night and day experience between the JR FMU and my Turboedit setup. If you still want a little more get it ported from stiegmeier he is way cheaper than Endyn and has more experience with eaton blowers, more with the GM and Ford guys but you get the point.

[KuehnD15B]

thanks for the info guys 6psi hmmm how much hp and tor. does that add i know on a turbo 10 to 12 psi like Doubles your horsepower....

[Dibble]

Queer!

I WIN!

[jdm ek4]

If any of you guys want i got a Kamikaze header BRAND NEW in the box. These headers are good for supercharged applications. Its the original Kamikaze brand not the Endyn version. Just thought ill mention this since you guys where on this topic.

[Toddnos]

you break rules^^^^read disclaimer

Quoted for Hand slapping.

General rule of thumb is that each pound of boost equates to 10-11hp on our motors. I can't say for torque. That is harder to speculate.

[jdm ek4]

Holy sorry...i had a feeling i was gonna get slapped for that reply. Sorry again
