I wouldn't twin charge with a JRSC.

With a centripetal supercharger I'd go big displacement to get torque or high ratio gearing so you are making 5-6psi off idle.

The only concern with gearing is having enough rpm left to allow you to rev your motor to 8 or 9k.

I'm going to say that if you want to twin charge, do a roots style supercharger like the JRSC, and run a turbo setup on top of it...mainly because belt driven superchargers sap a decent amount of power on their own, so adding a second one may be a noticeable drop in peak power. I have nothing against superchargers, and your build is awesome (love how clean it is, i'm jealous of that), just the power loss from multiple superchargers would be pretty huge.

Yea i hear you guys, iv seen one guy with a twin charged setup using a jrsc and turbo combo i was curious if the pro charger would be a good idea since its design is almost the same as a turbo and its driven by a belt to.

Im deff gonna do my second round of upgrades which is more boost shooting for 12psi any more i think im pushing my limits, a tri y header and a 70mm tb and retune. im sure then its gonna be a blast at 300+ hp. But i wonder if that will be too much stress for a stock block! over 300hp.. my last setup made 285hp with 12psi so i dont think it would matter but i do want this motor to last..

Too bad they didnt make this for the D series ... this is

just pick up a rotrex unit that's sized correctly and fab the mounting

wunfstgsr

anyone else with pro charged setup?

great numbers for sure!! props on the build

i thinkk ima have to get me one of thses now! i got one on my chevy small block , but damn i never knew they could crank so well on the ole 4 banger lol
great job on the build.

That's the rotrex super charger unit not the Pro charger unit, its much different and sounds completely different! i havent researched these much but i think it might be a good unit im curious how it performs! i dont doubt one day ill get one of those kits and compare it again vs all the other superchargers iv used on this ITR motor.

Thanks man!

Ow yea these 4 bangers come alive when they get boosted!

wolve

i know it's different, no gears so no whine and it makes a tad more midrange then a vortech/procharger. other then that, quite similair!

Westrock2000

I'm guessing the main reason for mounting it like that was to match the rotation directions of the engine and charger?

wolve

ccw engine + cw charger = funny mounting

wunfstgsr

im interested in the rotrex unit it be nice to have a bit more midrange.

i believe so.

It works well, the blower is in a cool area and besides it doesnt get hot anyway, but its pretty easy to install which i liked!

bump i wanna find more pro charger setups am i the only one in a hand full?

im curious, how much did you pay for the new block and head from the dealership?

wunfstgsr

bare itr head with vt= $1,500+ from ebay
complete assembled block = $2,500+ from ebay

DAm..!!! I missed the Dyno. Haha. If I would have seen this post earlier
Good stuff sirr
Hey I can get u deals for dynos at Do It Dyno
So we can see what u put down to the wheels

Holla at ya boy for the hookup

lol no worries ill be back at churches with more mods soon like a race header and 70mm tb and 10-12psi boost! i think i should be around 255 whp @7psi im shooting for 350hp soon on the stock motor.

I like the sound of these pro charger kits, I am currently running a stock Jackson racing sc making 250+ @9psi on my c1 in an 89hf and im well into the 11s with this power to weight ratio. I am preparing to spend a big chunk of change to step things up to the next level with the jrsc set up but if the prochargers are making this kind of power so easily I'm curious how one would fair being set up on a 2.0L with descent compression Ect. I would really like to see a procharge dyno sheet for comparison to a jrsc dyno sheet. It's ridiculous what linear power can achieve... And that's why jrsc and n/a cars can do so much with so little. It would be cool to see some comparison data or something along those lines. Idk if anyone knows but if this kit does take more time to create the power why not get a very efficient ball barring turbo set up? Or are these prochargers kind of an in-between type of power band ?

wunfstgsr

Whats your setup? your making 250+ hp or whp on a b18c-1 gsr motor? have you dyno tuned the motor?
A 2.0l stroker motor would be a good torque maker with the procharger, i wouldnt do it unless it was a full race motor.
I have my thread link on the first page, there you can see the jrsc motor i built that made 230hp @5psi and then i built another jrsc/LHT setup on a ITR motor that hit 285hp @12psi.
This is the same motor and cams with a Pro charger @7psi making 275hp!. once i retune this motor with its new mods and 12psi i will have a real good comparison because both the previouse jrsc/LHT setup and procharger setup would be pushing 12 psi with similar mods on the same motor and cams!
It doesnt rev you quick into vtec like my last jrsc/LHT setup so it does lag just a bit but not much, 1st and second are just as fast but when vtec hits you really feel the power, its not like turbo cars iv driven but similar in its lag only that my motor is fully dyno tuned compared to some turbo cars i have drove, Turbos are much more hassel than this kit and need oil lines taped and break down momre often. This unit is also C.A street legal! and theres no real turbo kit legal to my knowledge for use in c.a for these motors, i could easily run a turbo kit but i wouldnt even bother, this kit is very simple to instal and its oil is self contained.

well im building a new Integra and i will be upgrading the the motor pretty soon, im gonna throw a tri y header with a 3'' collector and 3'' catback with a 70mm tb and 12psi hope to hit somewhere around 300-340hp.

Langford360

Yeah it is dyno tuned and makes 255whp and 175trq. I don't have any aftermarket cooling though so that is no help lol. I would just like to be able to ride in a car with an ati pro charger to really find out what it's like. I have been in several turbo cars that don't tAke much time to spool but my jackson racing set up still works them on the street and track and they are making quite a bit more power. I like the disgn and numbers the ati prochargers put out but It won't do me any good of it's no better than a good spooking turbo setup lol. It's just that ever since I started this jrsc build I have lost all interest in crazy high horsepower builds. I have a personal friend who makes 528whp in a k turbo intergra and runs 10.7s in the 1/4 but off the track my 11.7 crx works him everywhere other than 4th gear rolls... So basically my next step with my build was to do some after market cooling and a 2.0L with the jrsc and get as close to the 300 mark then spray it will a small shot of nitrous into the 10s. I'm fully aware that the faster you go the harder it is to pick up time but I feel just getting 300whp out of the blower set up will get me well into the low 11s the add a squeeze of juice and that should do the job haha.

wunfstgsr

Maybe when i have both my dyno graphs to compare i can show the diffrence in how each sc performs, im confident the pro charger is going to be better just from me making 10hp less with only 7psi compared to the jrsc/lht setup i had that was at 12psi! But i did like my last JRSC/LHT setup @285 hp it was a beast!, i didnt get to upgrade the mods further but i had a pretty good setup that impressed my tuner. It had good low mid and had a bit of peak power that hit 285hp i was killing evos and stis and other turbo higher hp cars. Im in the process to getting this setup back at churches for a retune. its gonna make 300+hp real easy and i cant wait hopefully all will go well.

deff look into getting a race version heat exchanger, and run coolant, use thermal tb gaskets and intake manifold gaskets, and a shot of nos will deff cool things up and give you a nice bump in power.

The fact that superchargers are belt driven does not affect their efficiency. The mindset that turbos get "free" energy and that superchargers rob energy from the crank is completely wrong. Turbo turbines are forcefed by greatly restricting exhaust flow, forcing the engine to do extra work to push exhaust out. No matter how you cut it, moving more air uses more power.

Roots superchargers are simply inefficient air pumps. In the quest to compress air, they spend more energy to heat it up than other types of pumps do. Centrifugal superchargers, on the other hand, are nothing more than belt driven turbos. They are just as efficient as turbochargers (and sometimes more efficient).

...

So, OP, using both supercharger types will not mean you have two inefficient power adders. Just one.

That being said, a roots supercharger will make a turbo spool sooner.
