I'm thinking about joining the "Darkside", but I need to know what is the max boost level a person can run safety with a stock bottom end for a ITR. Help me out fellas! Thank for the data.

Cal

 

I'd stick to 7-8 psi

 

6-8 is good but depends what management you are going to run.

 

10ish lbs all day, as long as you have proper management

 

Tuning with Hondata S200

So, you guys think that boosting at 10lbs with proper tuning would be safe.

 

how much whp do you want to have?? maybe you won't need that much boost.

 

I would stick with 6-8, although I bet 10 can be pulled off

 

The size of your turbo is also a huge factor in this.

You are not going to run 10 pounds of anything through a stock c1 with a t68

With a good sized turbo between 7-10 PSI and some tunning will be fine.

 

I'm shooting for 200 Torque.

I'm probably going with a supercharger.
This one in particular http://www.Procharger.com

What do you guys think about this product?

If you are only shooting 200 WHP I would say go for the JRSC.

Even the base run with a bone stock ITR and a stock pulley put down like 204WHP on a good friends ITR.

I cant comment on the procharger because I have never used it

 

I've seen that procharger on a civic si and it sure was sleeper. Everything was hidden from view. Looked stock except an intake and header.

 

o.k.. so 200 torque is about 275hp at the wheels, thats if max torque come around 7Krpm. Either way, you could acoomplish that with 6-8lbs, and probably turbo.. why not turbo?

 

Dennis,

Shane from Autowave gave me ride from a passenger view. That SI is "SICK"
That car was pushing me back into my seat, for a moment I thought I was in a mustang. That car pulls so hard! It would hand my *ss to me in my ITR! I agree with you about the setup. It looks to stock and that's what I like about it.

 

Go for it man, cause if it works out, I'll do the same

 

i heard that si put 230 to the wheels. when is the procharger coming out for the itr or gsr? i heard they have one being tested for a B18b.

 

if that procharger is anything like the vortech, the powerband wont be that great

 

Have you been given a price quote??

 

with good tuning its not about boost its about power (whp). A stock motor is good/ safe for around 250-260whp and 200trq. However if you start to make more then 250-260whp you will start to wear on the motor big time. Why? The big weakness with the motor is the piston lanseals. With good tuning you will probally break them first. I would suggest making 250-260whp if you have really good tuning or if you want to be safe, put a Greddy headgasket on to lower the compression to be on the safe side.
Also the procharger as with the vortech kit will put out really high peak numbers, however the low and mid range power will be sluggish since the charger doesn't reach full boost till around 7,000+rpms. With a JRSC (jackson kit) the peak boost is practically reached the second you go 100% throttle. However the jackson kits are boost limited and require good tuning if you raise the boost on the stock motor.
I run 10+psi on a jackson unit on a stock motor, however I have a fully programmed ECU and various parts plus really really good tuning on the car. Currently I'm at 285+whp and 200+ trq, however I would not suggest this for everyday driving since the wear on the motor will be greatly enhanced. I only average under 6,000miles a year so I'm not to worried. Also I'm still on 91 pump gas, yet I'm thinking of just running 100 since a station by me carries it and I can tune the car for more power.

 

I don`t like where the charger(pro charger) is located. If you hit something on the road it could take it out.

Exactly, I was looking at that as well.

 

What Steve said. Vortech/Prochargers are dyno queens. Great peak numbers, but little to offer in the real world over a comparable Jackson setup or turbo.

 

Werd. It`s like the worst of both worlds.

 

put a Greddy headgasket on to lower the compression to be on the safe side


why does everyone think that you have to have low compression in order to be safe?????????????? get the fuel correct and keep the knock out, it's that simple.

Low compression is for girls, tune that chit with normal compression and gain all kinds of mid and bottom end pwr.


P.S. Yes, I do understand that you can't run 20+ lbs on a 18:1 motor on pump gas, just stating that anything 11:1 and lower will easily handle low, double digit boost figures.

As the smart people say, "It's all in the tuning"

P.S.S any type of centrifugal blower is gay peak #'s don't mean chit to me

I said usa the Greddy headgasket if he can't get good tuning to run high boost with stock compression to be on the safe side. High boost with stock motor and poor tuning is stupid. At least with lower compression you have a larger margin of error with poor tuning.
And trust me, I've probally pushed more boost from a supercharger on a stock type R motor then most people. I'm just able to do it fine since I have really good tuning.

 

Why, do you say that "Centrifugal Supercharger" is Gay?
