So anybody with the kit plan to raise their RPM levels pass 7600?? perhaps 8600?? 9000? Top speed increases? 160?? Just curious.

Can that be done? I thought there was no way to defeat the rev limiter?

I'm sure the ECU can be reprogrammed..it's just a logical guess..

Interesting..didn't know that JBX. THat leads me to another question...By going to OBD1, will you be able to pass smog still with a different ECU on board??

Passing the smog test, I'm not sure about this. I believe SunDang did this conversion. Perhaps he can comment on this.

It is to dangerous for the car and to much pressure on it to have a high redline and the JRSC, all those ecu's for sale are advertised as not to be used with a supercharger.

There are a few problems to doing that. First, no noe reprograms our 5th gen OBDII ECU as was pointed out. Not yet at least.

Raising the rev limit means you also ought to rebuild the whole head to handle the additional stress. Lightened & stronger Valves, better springs & retainers etc etc. This also does a job on your bottom end. forces are exponential down there... Especially critical if you're running any kind of forced induction.

Fuel delivery gets touchy too so you have to be sure you're not running lean.

It's not as easy as just bumping up the limit. Domestics can get away with it a little because typically they're not tuned worth sh%t from the factory.

Right where-abouts where I thought, just wanted to make sure that's normal. I had always thought it was 8K.

I'm thinking...where will the JRSC peak horsepower be at? Of course with the SC, you will get more torque at low rpms right? Will the SC also give more hp at higher rpms.. I'm sure my logic is flawed somewhere along the line though.

Any one read the article on the red prelude owned by Jackson II. He said he can blow the needle on the speedometer no problem...goes like 165 mph. I don't know much about the JRSC, but all the times posted 0-60, 50-70 etc. were greatly improved....50-70 was like 1.9 sec! about half of the stock setup

I thought it wasn't possible to go beyond 140mph in a Lude? Not sure of the details but someting to do with the bearing mechanism...?

Could someone please refer me to a specific month and magazine for this article. I'd really like to get my hands ahold of it and see what was written. Thanks.

Revving any H22 with the stock rod ratio to 9k RPMs is NOT a good idea.

I would say maybe 8200 RPMs max. Besides, with boost, there is no need to wind the engine out that far. Really depends on where your power peak occurs. If it occurs too high, lower it some. 9k RPMs is terribly harsh on an engine, and even worse on engines with bad rod ratios.

To quote TOO - "RPM = Ruins Peoples' Motors"
