Here's mods...

2.5" Collected Header
Cone Filter
E-Fan
Removed A/C
Blue Thunder Racing wires & NGK Plats

...and mods in the very near future:
HKS Hi- Power Mufflers (the eBay kind of course )
CAI
Street/Half Bridge
Bigger Injectors (I'm thinking 550-750cc)
Better Fuel Pump (I've heard very good things regarding Walbro 255lph)
Adjustable Fuel Pressure Regulator
A'PEXi SAFC II
Venom 400 Performance Control Module
NOLOGY Spark Plug wires (the ones with the built in capacitor)
XACT 12.5 lb Flywheel.

Now, my estimated numbers for hp at the flywheel on current mods is 175-182ish and to the wheels I'm guessing 145ish. Is this a reasonably accurate assumption or am I having a pipe dream?

Oh, I don't know if this is close either, but with the future mods, I'm estimating about 280 flywheel and 240 wheels. Is this right? Thanks.

Bump.

You're still N/A right? Do you have a TII drivetrain? Asking this because of the XACT flywheel, since it's TII only


Other than that, that should be a fun car to drive. If it wasn't for having to pass emissions every 2 years I would've gone half bridge on my recent porting too, but since I have to I had to keep it within reason (even though I still have to cheat).

1RevvinFC3S

Thanks for responding. Yes it is N/A, and DAMMIT that sucks that the XACT is TII only. I guess I should do some more research. No I don't have a TII drivetrain. And how do you cheat on emmisions?

Oh, does the Venom 400 exist for our cars?

ddub

No problem. Yah it does suck, I even started a thread asking and most people weren't sure, so I emailed rx7store.net and they cleared that up for me

For me, I passed emissions with no EGR valve, no ACV, 1 main high flow cat, and no vac rack or solenoids. I have the high flow main cat in with the split air pipe running up into the engine bay and then I ran some big *** heater hose from the outlet of the air pump to the pipe so that the air pump was pumping in air ALL the time instead of just sometimes, plus it was putting in more than the ACV normally would allow. Also had my s-afc adjusted to -20 or something at idle (515 idle woohoo!!) barely wanting to idle, and then had -12 or something up to 3k (also was running a TII fuel pump still, too lazy to take it out).

Got 84 or something HC at idle with 0.02 CO% and then 73 HC at cruise with 0.01 CO%

ddub

Oh and the cat only went in for the day of the test and was imediately taken out. Otherwise it'd fry it getting air all the time.

As for the Venom400, no idea.

the flywheel will fit the na tranny, but I still suggest going with a t2 tranny, as mine lost it's syncro's at about 190 flywheel-horse. I have a t2 tranny in my car, as long as you use the same cluth assembly as the turbo it should not be a problem. the bell housings are the same the input shafts are the same. the only difference between the 2 trannies is the internals. the t2 can hold 500+ ponies and the N/a can barely hold 200. I suppose a regular driver would not notice the difference in the transmissions, but once you race the N/a you can tell what it's weak points are.

ddub

There are plenty of people that have and do run more than 200 hp at the WHEELS on an n/a fine.

mr_sunshine

I've had a couple people tell me the same thing. my own personal experience has been bad though. They say that the N/a can usually take a good beating, maybe it's my driving style, but the t2 is still stronger and more apt for racing.

1RevvinFC3S

Well, I guess it depends on how you launch if you drag it. I personally don't launch hard, at ALL, and don't do long burnouts so I'm sure my tranny will be fine until I get enough to get a TII tranny/TII (car).

casio

flywheel back, n/a and t2 are different. dont try and mix the 2.

dDub, who's running more than 200 at the wheels? most people who've posted have been around 175-185 for most in an n/a (street of course). not many people have a standalone and nice ports on an n/a. i am yet to see someone break the 200 mark and post something. i know its been done, but as far as typical street cars, i dont know of one.
good luck tuning the half bridge with an s-afc. try to find someone who has; i never did. i dropped my entire 6 port system and went with a streetport. i'm glad, too, because i have to pass emissions (in the middle of trying to get legal now).
thats weird, they dont do idle testing in my area; only 15mph and 25mph. i failed (air pump not yet hooked to cat), but it gives the rpm he was at, so if i were to fail with the air pump hooked up (god i hope i pass), then i can have the s-afc installed and lean out those rpms a tad.

i highly doubt youre going to need 750cc injectors. if you did do a half bridge and get it to run decent on an s-afc, i'm sure the 550s would be enough for your power.
if you want a light flywheel for an n/a, find a racing beat. theyre the only one i know who makes an n/a flywheel.

Aaron Cake, Sonicrat, lots of other turbo'd N/A guys that I've seen (not from this forum necessarily), uhm JudgeITO's daughters N/A is running nitrous with 200.3 rwhp, I could go on but you get the idea.


Why do you think it'd be hard to tune a half bridge with an s-afc? Especially if the bridge portion is on the AUX ports then it wouldn't even be open at idle or until 2800 rpms or whatever the crap it is when the aux ports open up (have no clue because mine are long gone). It's not like it's a turbo'd bridge where you have to worry about overlap as much let alone boost.

1RevvinFC3S

I've been conteplating nitrous too because my brother is running it and he's pretty damn happy with it. Of course he's about to get a TII so that sucks...for me...good for him.

casio

turbo'd n/a is nearly an oxymoron. i meant 200+ n/a, not n/a block. big diff.
it can hard to tune because it may be more air than the stock electronics can read. its experimental territory. judge ito has done a couple of full bridges on stock electronics, but they were S4s. the electronics are different enough. apparently the AFM is better as far as range. most of this is claims i've gathered. i tried to research doing a half bridge on my 91, but came up short and decided it was best to stick with something that will run properly on stock electronics. mazdaspeed7 did a bridge on the aux and i believe he said he would never do it again. if it were that easy to cram air into an engine and expect it to run right, we wouldnt worry so much about stand alones. not as quickly at least (i wouldnt mind driving a car so-many months that didnt run perfect while i waited for my standalone). if he can get a half bridge running right, awesome. i'm just saying that the stock ecu and accessories may have trouble keeping up.
i believe the ports open about 3800. if i were going to do it, i'd do the full iron, not just the aux. also, i'm not sure how efficient air would flow with one normal port and one with hellacious overlap on the same intake runner track. thats up to fluid dynamics which i cant argue. moreso, theories are just theories; i prefer some physical representations.

And how was I supposed to know this? You chimed in when there was a discussion of whether the n/a TRANNY can withstand 200+ hp at the wheels, therefore I was assuming you were talking about other people with N/A blocks and N/A trannies running 200+ whp. If you want to talk ones that have stayed n/a and hit over 200, then sure we can talk. Yes you are correct there are not many... here. Go over to nopistons.com and search around. There are n/a guys there with peripherals, half bridge/peripherals, full bridges, etc, anything you can think of. A stock n/a block with a peripheral port goes beyond 200 at the wheels easily, and there are people that street drive these.

ddub

On a side note, if I had a bunch of money and wanted to build an N/A I have no doubt what I'd do. S5 body, super lightweight rotors for high rpm use, race bearings for high rpm use, peripheral port rotor housings and irons, full peripheral port, full custom exhaust to go along with it, custom intake of some sort (depending on the manifold and TB situation), standalone of course, the custom intake manifolds would have to be made with custom TB's, fuel to go along with it, full TII drivetrain, msd6a for the leadings, msd dis2 for the trailings, sufficient cooling, clean exterior with new paint and tint, stripped interior except for 2 racing seats and the dash/console/surrounds black keep the cd player and rear speakers, full roll cage with harnesses, after that I'd see what I'm putting down and running and possibly add a 75-100 shot of nitrous wet system.

I'd also aim for a 9-10kish redline.


Remember this is if I had TONS of money to blow and nothing else to do with it. I doub't I'll ever even see a car like this

casio

sorry for the mishaps; i know there are and can be 200+ whp n/as, my point was that they're rare. not only rare, but not entirely simplistic (when speaking financially, mainly). on another note, i chimed in when i saw the thread. he was expecting maybe 240 to the wheels which, from what he listed, is a pipe dream.
as far as the tranny, i couldnt care less. i never even intended to refer to the trannies. i know people have run turbos and such on them, but for most its a temp thing. come on, though, you know i've been here for awhile. i'd have to post blind-folded to miss the guys running turbos on na drivetrains. but lets put the trans conversation to rest (between me and you at least).
as for breaking the 200whp mark, i'm gonna venture to say he'll need to go standalone or carb with a decently sized port. i was earlier referring to stock electronics. he never mentioned standalones or carbs. in fact, he was going with the s-afc. i'd like to see an S5 n/a, stock ecu running an s-afc hit even 200whp.

ddub

Judge ITO has done it time and time again, with and without nitrous.

casio

i only know of his two S4 bridgeports on stock ecus. and nitrous i still dont count. a geo can make 200 with nitrous. i'm referring to n/a. first, i'd like to see a stock ecu S5 (very important that its S5) hit 200 to the wheels. when and if that happens, i'd like to hear how well it runs and how it was acheived. i'm not saying it cant be done because i dont know. but again, i dont know of one.
