I have K20A Motor w/ JRSC, Hitting 6PSI. I want more power. Please give me some Suggestions?

I could lower Compression and then Boost more PSI? But that might be a waste of $$.

Suggestions anyone?

Do they make an intercooler or an aftercooler for the RSX JRSC? If so I would suggest doing that and getting a bigger pulley (or smaller which ever makes more boost ). Like I have said to you befor I would not lower the compression.

If nobody makes anything as far as aftercollers and such for the JRSC kit maybe try contacting LHT they make a reaaly cool internal cooling kit for the B-series JRSC kits. I'm sure they would not mind breaking open a K-series Kit...

Thanks man, I could upgrade the Pulley to a 9lb. Pulley..But then I'll push more PSI..Isnt that bad for my Compression??..

 

[ongwoeiluen]

besure to change injector to higher cc and pls make sure your engine running in enough fuel condition bro by the way nice setup

 

[Bubz]

yup I wanna upgrade the Injectors to a higher cc and 9lb pulley..but i dont wanna blow my engine w/ my compression. is it ok to run 9psi on a 11:5:1 compression engine with stock internals?

dont worry about that , i had run my b18c5 with upgraded piston domed, i was at 11:5.1 and i run my turbo at 7-10 psi dosnt blow, always reflect on your tuning, the guys who tune the car he have the magic touch in his hand.But for sure its more risky

 

[Bubz]

Well my Pistons arnt upgraded. I was thinking maybe a Thick Head Gasket? To bring my Compression down a bit.

It wouldn't hurt to drop the compression a little bit, but if it is tuned well it really isn't a problem. The tuning is where the risk really comes in to play. if you run 9psi on an untuned 11-1 or 12-1 whatever it is you are asking for trouble. But if you get it tuned by an experienced tuner you will be fine at that compression with that kind of boost. Although from what I have always read about the JRSC kits they are effected by heat soak, the supercharger just gets to hot after any period of time and the air it is compressing starts to ubsorb heat from the supercharger therefor not producing as effectively as if you where pushing colder air. I would look in to a way to cool down that air befor you look to up the boost. but I wouldn't be to concerned with the compression at this point.

What kind of ECU are you running?

How do I cool down the Air? They dont make a Intercooler or Aftercooler for this car..I have a AEM CAI in the Fender?..

Hondata K Pro

and I have an Awesome Tuner..100 an hour to tune..

 

[Baylor0u812]

buy a turbo

 

[TeamPacman]

buy a turbo

:up:



Or get a custom pulley made...

 

[Bubz]

I think Im gonna try to getta K24 Pulley for more Boost on my SC..But I dont know where to find 1

 

[K2e2vin]

maybe water injection to help aid in reducing detonation(and cool the intake)?

 

[wsuk20]

Compression issues come into play with fuel choice and boost levels. If you are running 93 octane pump gas you will probably be fine on pump gas, but I would retard timing a little bit to be safe.

As far as heat soak goes, hotter air is going to be more prone to detonation. I havent used K-pro, but if it has a timing adjustment based on air temp I would definetly get that dialed in.

Water/methanol injection is also a good choice to reduce air charge temp and detonation.

Or if you just want to make some more power without doing to much work, try getting a set of Ron's forced induction cams. tehy are good for another 60hp or so I think...

and I think crower came out with an FI cam as well...

 

[Bubz]

I ordered my K24 Crank Pulley and my 650cc Injectors...

Thinking about lowering my compression w/ a Head Gasket..Wont lower it much but to at least 11:0:1 Which should be okay..or I might stay where I am. Im hoping on 9PSI when I install all this..Im ona 3.4 Pulley 2.

 

[Matador]

You;d be ok upping The boost but the thing thats dangerous isnt the comp. But the intake Temps when boosting so high with a JRSC with out a way of cooling it.

U mean the Air Intake Temp? I have a AEM CAI..Hondata makes a Heatsheild that helps

 

[jon v]

No he means that the supercharger heats up teh air befor it goes into the motor. there for the heat shield probly won't work. You can think about getting a hondata intake mani gasket, but that still won't help to much. I'm telling you if you want to do something about those temps give these guys a call and talk to them a little bit, they have some experience with the JRSC kits...

leave the boost alone and give it a small shot of n20
