Well what do you have to say to that RG?

I'm mega postwhoring in here but once it starts including my car I'ma postwhore as much as I want. Also did you want to do the true duel exhaust set up that RG was talking about? We could just tinker with porting first if you want pure dyno numbers and maybe go true duel later? I don't know what this involves labor and materials wise I'm just throwing ideas out there.

Also how do I measure the egt?

If you and RG come to an agreement on something I'll need to change my pants I'll be so happy. I just want this to work out in the end for the best.

And will this all help my car's lifespan cause effectively my car has to try less to perform it's normal duties? If so I'm sure me speeding all the time will negate it but it's good to know.

i don't think it will do anything to the lifespan, and not much for the efficiency, but possibly better fuel economy...but then again, possibly worse. one thing though, i'm sure it will make more power.

rg and i aren't exactly disagreeing, i think i've seen a little more in reguards to the coolant passage because i've got it right here in front of me. if he were here, he'd see it too and i'm sure we'd have a very similar, if not the same, opinion.

just so you guys get an idea of how thin that wall is--think about the intake ports on the fc's...it's even thinner than that.

you know what i really like about this is we're both voicing opinions in a respectful way--and even if we do disagree on anything, we're not stepping on eachothers toes or trying to cut eachother down. try getting that on some of the other forums!! :D

Man try getting that on this forum sometimes. No j/k. This whole thing is awesome and I'm very lucky to be a part of it. What do you think about the dual exhaust also?

i think he's got an awesome idea there and i'd definately like to try it--just not on this round. i think that may be just a little more work than i want to do for free. lol

Here is a crude outline of where I'd want to run the exhaust port to. How are you hitting water if you aren't going any larger than this. Take a picture of it somehow.

because the coolant passage actually does this:

I got ya now. I would probably only port it up to that point and not past. spend alot of time cleaning up the inside edges. I'd do this on the first one and then maybe get more extreme in the future. I'll probably just have to spend the money and buy a housing so I can port one and make my own templates.

this is actually a tad bigger than the actual port... keep in mind i port better than i draw.

if you notice the "red zone", that's where the leading edge of the rotor passes by the port. i kept material there to make sure the side/corner seal junction was supported throughout its journey through the engine.

hope this clarifies it a little more.

when you bevel the edge, you can actually get a pretty hefty radius on it--just can't do much along the vertical axis without hacking into it. seriously, it's about 1.2-1.5mm thick...optimistically

so the port ended up a bit narrower than i'd like, but i'd rather have the side/corner seal supported. taking that corner out wouldn't be any big hp improvement over the way it is, so better safe...

Alright this all sounds awesome. Inluding being safe with the side seal because that seems to be the part where everyone doesn't wanna screw with. I was just tossing ideas out there before. But, if this porting works out well I'd be more than willing to pay for the true duel exhaust of course :D

any possibility of making it up to my house this weekend to look at the one that's almst done and maybe shoot off some pics?

I work later today 4pm-10pm, 2marow 6:30am-2:30pm (Nordstrom)/3:00pm-10:00pm (Pick Up Stix) and Sunday from 10am-10pm..ahh the life of a student trying to afford gas. I could go up there saturday night if you have enough lighting that late, or monday I'm outta class around 1ish and I have the rest of the day free so we can try and do that? I'm sure we'll get something soon.

Nice information. Keep up the work!

i think we'll start a new thread once it gets under way--just so people that wanna see don't have to flip through hundreds of posts...

i'm expecting good results. nothing dramatic, but a nice solid gain across the rpm band.

That sounds good to me, considering we can't get a lot of the across the band power. Most of the bolt-ons add a few hp to the top end, after 7k rpm or so. Good luck.

i'm looking for solid, duplicatable results as opposed to just the end number.

Man I can't sleep I so want this like yesterday

... that makes two of us Snoochie Boochies! :D

i'll warn the rest of you that if this pans out, look for the porting cost to be relatively high--as it's about 5 times the work of the rx7 motors!

but ther than some very minor cleanup work, the first one is DONE! :D

can not wait to see the dyno results.

Cannot wait to see some track results. :D

I can understand not wanting to totally punish your car though. Isn't there some sort of standard 5-60 "rolling start" test the magazines do? Basically so you don't trash your clutch and transmission.



(and Vince, weren't you banned?)

it's be great to get all the performance specs with and without the porting. i think the most important thing of all is going to be snoochies butt-dyno. how does it feel? how do you like it? etc etc.

i guess time will tell. as long as i've got nothing to do when he drops the irons off, it should be a one day turnaround-maybe 2. now it may take up to a week if i'm busy, but i'm anxious to get it done ASAP!!!

Yup yup. Should I get my brother or someone to drive up with me just in case I need to leave it there over night or for an extended period?
