Correct; we have several engines to build, ship, and install, so I am quite pressed for time. You have first-hand knowledge of my penchant for "chattiness", too, so ....... LOL

Really, the only curiosity I have at this time is the mass airflow data across the RPM range at WOT as compared to an otherwise similar (but unported) Renesis, but I don't believe you "owe" any of us anything on that matter.

Bingo. As compared to a street car engine, it's not going to see those sustained high EGT's that will otherwise challenge the integrity of that seal spring. What occurs after hours of running it is a slow loss of compression that gradually gets worse.

You want any certain gear for load? I can pull that info pretty easily with my AP... As well as some table data for like MAF tweaks that Kane made for me. We were getting some weird numbers when he was messing with it.

a 2nd or 3rd gear log run on a level road would be interesting

Will do. I'll get it by this weekend.

sounds good, you're in TN right?

reddozen

iTrader: (1)

Sure am. Weather has been up and down the last couple weeks.

Brought the AP with me to work.... and it's raining... Hopefully tomorrow will be better. The weather says sunny, but you never know.

Also, if you happen to be aware of any modifications to your MAF calibration that would also be helpful. The only issue with looking at MAF readings for comparison is if there has been any major changes to the calibration it could result in skewed readings.

It's been adjusted. I planned on listing a lot of info on the excel file. I'm way ahead of you.

TeamRX8

If you base it on that you will be guessing regardless.

Check your PM bub.

Raising the rev limiter would also be fun if the first logs show a different power curve.

Ok so how much is BDC charging for a mild port?

/\ nice lol

I figured one of you already knew the details and that he'd already been bombarded with messages about this before so I didn't want to bother... but I guess not

I am sending you a PM.

People who are in business not only expect but prefer that you contact them for real facts rather than second hand information that may be out of date if not completely wrong.

but what do I know, I'm still trying to understand why it's called "common" sense ...

JeRKy 8 Owner

Dunno why but I feel like this is a much more stable way to get decent horsepower improvements without killing off much engine life than F/I. A mild port that is. Just a hunch

reddozen

iTrader: (1)

If you're satisfied with like 20~30 more HP for the time / cost. Porting alone wont touch FI.

WTBRotary!

There's nothing like Boost...

BDC

Agreed, but helping the engine breathe better per stroke always helps and I think it's worth exploring more on the Renesis in NA form.

I don't think you were a member back in the days when there were all these notorious threads complaining about Mazda's incorrectly advertised bhp and whp figures...but if I remember correctly, the numbers everyone was pulling stock were about 20 - 30 hp shy of what was expected. If only this solution had been discussed more frequently here back then...

And I'm a lazy ***. If this mod can be done without having to run some type of Emanage crap on top of it afterwards then I'm all for it. Plus all the issues I have heard about from other owners (not on here but in real life) about the excessive maintenance needed with their boosted 8s to keep them stable has prevented me from even considering the F/I route. Not interested in doing something to the car that will hinder peace of mind...especially when these engines already come from the factory with problems LOL

EDIT:
Err...I just spent the past 20 min sifting through reddozen's 400+ posts...and wow. What a pain in the *** this process has sounded like. You had to get it tuned a couple times too for it to stabilize. I really thought this was a plug and play type of deal. So now I'm withdrawing my previous comments about this bridge port stuff being for me. Worst of all, you still never managed to get yours dyno'd this year, what with the divorce and wedding and everything. Poor bastard.

bse50

Just buy an accessPORT and have somebody tune the car.

Or... buy a NA PP race engine for 7-11k$ and enjoy 290ish NA rwhp.

I really don't see what's the problem with a ported engine or a turbo setup. Even in reddozen's case it was a user (self-tuning), not an engine issue.
If you're so scared just don't buy real performance parts and stick to what doesn't work!

Flashwing

The aspect of being "plug and play" is a matter of perspective. If you are performing the majority of the work then obviously there is a lot involved. If you intend to drop the car at a shop and have the labor, machining, and tuning performed prior to you picking up the car then it can be very much "plug and play".

Anytime you alter the engine airflow tuning is required to ensure the engine runs properly.
