I am wanting to know what kind of gains you H22 guys have seen with some port and polish work on your race engines. My new race setup:
13:1
Crower Stage 3 cams
all the other fixins for a good all motor setup

Who have you gone to for head work and what have you seen from it?

 

Saw a thing in a Magazine that made 15 hp from a P&P on an H22.

Hope that helps

 

What mag? Who did the work? I need more info than this one place in this on mag made X hp.

 

if your actually gauging intrest in 15hp off a race motor I don't think you've done enough research. I find 15hp off a good "race" p&p kinda weak especialy with 13+ comp. but whatever

I belive the magazine was in a super street article and the company was r&d the way they work is you send your stock head in and they'll send you one of their premade heads. LAME

R&D Dyno did the work. http://www.rddyno.com
It was in Super Street October 2003 Edition

It made the power on a bone stock motor. It was a bone stock motor (stock internals), and the head was CNC Ported. All the valvetrain was left stock, and the cams were left stock. If it makes 15HP on a stock motor, the gains would be higher on a built motor.

Would you rather you send in your stock head, they port your stock head, then send it back to you? This would mean a longer turnaround time. Again, I'm sure some people would want their original head back.

However, some people want a quicker turnaround time. If they send you a premade one, it's because they want it to get to you quicker. They then take the one you sent them, CNC Port it, and wait for the next customer to send in their head. However, I don't think they do that. I think they port your own head and send you the same one back. The only reason in the magazine they switched heads is because the magazine wanted to be right there to see the base dyno of the car in the morning, take the head off, put in a CNC Ported Head (w/ stock internals), and then dyno again towards the evening when the temperatures are the same as it was in the morning.

This is why the head makes good gains. After many trials and errors of porting and polishing H22A heads, they pick the one that made the most gains, and then have all the aspects it scanned into a computer. They then load the scan into a CNC machine so that it can port out a duplicate of the head and do it the same every single time.

 

It's kind of scary when a shop claims 20 hp gains and then spells VTEC "V-TECH."

I think it is scary when a grammatical error is pointed out within a sentence that has one also. Someone needs to go back to grammer class to learn the correct useage of "then" and "than."

 

Sorry laughinxxx I couldn't resist. I have an English degree, so I thought your point was kind of amusing.

On the topic at hand, I'm sure R&D will use your head if you want them to instead of sending you back one that was already done. Most people tend to be impatient, so that is probably why they do that.
