like i have itbs installed..

WHy are the pics not working for me??

I am really tempted to do something like this. Especially if it helps with cooling and throttle response!!

AAAANNNNNNNDDDDD DYNO NUMBERS!!!!

Wait for it,

Im a VERY happy little camper :)

Time for some tuning gear. That 4-4.5k zone would make me a bit nervous. Or was that with Meth running?

Looking good though :)

The afrs are off. Their sniffer was busted. My afrs are 11:5-11:3

Nice numbers, what kind of dyno is that?

Phil (levnubhin) has driven my car a few times and can attest to the power the car is making

Those welds made my dick move

Ok heres everything. Every variable that I know of and the whole thing so everyone can disect this and discuss it with ALL the info on my end available.

When I bought the car, it had 19k original miles on it. Within the first two weeks, i was already pushing for what I have now. I started out with lots of reading here and elsewhere, coupled with what I already know about Turbocharging etc. etc.

Started out with wanting to get rid of the Bog and did what alot of other people did so I bought the full FM intake kit with the 02 modifier. I also bought the common ebay intercooler upgrade. Ive been a customer of Flyin Miata for a few years and they have always produced some of the best products for our cars, and have one of the nicest, most knowledgable, helpful staff yet to be experienced for me (dont worry Bell, I love you guys too lol). So with that, I started on the commonly traveled route for the majority of folks. (End FM, Begi love lol)

I loved the intake and all but I wanted more. I still had my bog issues and lean spikes with the stock ecu and my injectors werent that great. My fuel pump was also starting to crap out on me so that needed to be addressed. My stock exhaust also was way too quiet and restrictive for my taste. So It was time for more reading and designing.

Call me crazy, but I love challanges. I wanted to do something different in the hopes that it would provide another avenue of successful, safe, and enjoyable power and driveability. Im not a person of alot of financial means so DIY is really my only, and if i had the choice, my only desired option.

I found the joys of unplugging the TPS and kept it unplugged only to realize that may AFR went way rich as in 11-11:5 in just normal cruising but it DID completely get rid of my bog so I took the trade off of driveability with lower gas mileage. I looked for ways increase the fuel mileage and achieved that but ill get to that in a bit.

I saw how people had gotten more boost out of tapping into the brake booster line. I tried that and it wasn’t worth it as my car didn’t do much with it so I bought a MBC.

The car was feeling much better and seemed like now I was getting somewhere. I bought an Aem Uego to monitor things because from this point on, I wanted to increase boost.

I tried the boost cut bypass zener diod mod and heres where things got interesting. After installing everything as per the write ups on here, I realized that my car just didn’t take to the mod at all. It started bucking and jerking like crazy throwing my afrs all over the place. After ordering a different set of diods, I got even worse results. So after taking the diods out for the second time, out of aggrevation, I turned the boost up on the MBC and floored the car. Low and behold, and I still don’t know how it happened, my boost cut was gone! I have no boost cut at all. The ecu I guess somehow decided to eliminate it after the failed zener diode attempts. I took that as a blessing and moved on lol.

I had the stock exhaust and cat out all the way up to just close to the turbo. I had 3 inch piping made all the way out to the muffler. After 2 mufflers, I decided I missed my old rotary roots and the noise so I had the muffler cut out and a high flow cat installed to keep the fuel odor down. I also got rid of all of my emissions stuff, egr included, and enjoyed the cleaner engine bay.

I wanted to see what my car was making power and torque wise to I went to get the car dyno’d

At this point my mods where:

FM intake, throttlebody inlet tube, 02 mod, GFB recirc. bov, Cxracing intercooler, custom 3inch exhaust, Turbo xs MBC @ 10 psi, supra 305cc injectors, walbro 190 fuel pump

This was my dyno vid from that day

YouTube - 04 MSM dyno run

I made 210rwhp at 198 pb ft of torque. Not bad but I wanted more, plus I was getting pinging as my IAT’s were way to hot. AND THIS WAS ON A DYNOJET.

Moving on I was beginning to see that I couldn’t afford a Hydra, or bigger turbo so I figured what could I do to maximize spool, torque, MPG, drivability, cooling efficiency, and power. I decided that to combat some of those things, I wanted to do a V-mount setup and coolant reroute. I figured if I wanted to get more than the usual results, that I need to go more than the usual route to get there.

So after all that was done, I had the boost turned up to 13psi and I wasn’t too comfortable with 12:9 afrs at WOT. I wanted a little extra cushion safety wise so I bought an AEM water meth kit. Best thing I could have ever bought. I turned the boost up to 15psi and after fiddling with the different jets, im using the largest one now. My afrs sit right at 11:5-3 at wot to redline in 5th and sixth.

So I come to the present. My mods and the way the car sits as of now:

1. No boost cut
2. 15psi
3. Meth (largest jet in the AEM kit)
4. Full 3inch exhaust
5. Walbro 190 fuel pump
6. Custom Vmount setup
7. Fully enclosed chanel ducting on the bottom
8. Ducting on top of the intercooler integrated into the hood vent
9. 305cc supra injectors
10. Coolant reroute
11. Swirl pot/ header tank
12. Cold cold cold iats now especially when I mix ice in the tank with chilled meth
13. MBC
14. CxRacing aluminum radiator
15. Custom AC lines with a working ac unit
16. Fully shrouded stock fans on the rad
17. AEM Uego
18. Autometer boost and water temp gauges
19. MMR Solid motor mounts
20. Ebay turbo outlet pipe

And I think that’s it.

The day I dyno’d then outside temps were around 78 degrees. It was a Dynocom dyno. I have a boost leak on top of that.

And that’s it as far as I can remember.

Im going to maximize everything on the IC ducting with some gold reflective heat film, get an EBC and thats about it. On a side note, I experimented with dropping some dry ice in my meth tank. I will be dynoing my car again but with the dry ice method to see exactly whaits doing for me numbers wise. I do know it makes a huge differnce in the torque, response, and power. My guess is that the stock ecu doesnt really pull much of or any timing once it sees the freezing water meth mix but I want to substantiate that.

For comparisons sake, heres my first dyno at that made 210 rwhp on the typical FMIC setup:

For giggles, heres the Dynolicious results:

And the one from the other day with how the car sits now:

Unfortunately the dynojet plot looks like ass but you can get some kind of idea

i dont think he realizes that we dont care.

I think you dont realize how much your new avatar ;)

Any thoughts on the power plummet at ~5500? Time for an intake mani?

looks great, I really like that gauge setup

:BSmeter:

This graph looks very similars to my friends. did you by any chance dyno'd this at all jap in sunrise? if you did, im sorry to tell you but you are not making no where near the power you think you are.
i went to one of their dyno events a few weeks back and realized that that dyno produces some real bullshit numbers. as a matter of fact eveyone of my friends said that dyno adds atleast 30+hp's.
take a look at my friends dyno sheet both dynos were done in the same day with the same psi. this is a Probe GT.

there is a thread on so Flo racing.com So Flo Dyno Day Aug 29th - Page 4 - South Florida Racing
its preatty lame.

but as far as you v mount setup that shit-s-kick-ass.

Sounds good to me! Im still happy with 230! Really though, i dont give a shit with the dyno stuff anymore. Thanks for the info though

props on all the DIY work! looks awesome, cant wait to see how the hood turns out.

i have one question though. what all did you do and have to go through to redo the ac lines?

Yea well thats the thing, you might not even be around 230... Realisticly you are between 212 - 218. As my friends results show a 42 hp discrepancy. I wish you had another dyno comparison, perhaps in the same dyno you origanally posted. Then we would trully get some accurate comparisons.

OH...and...stop threadcrapping. This is the kind of shit that should be in PMs...otherwise it makes you look like an asshole. I understand you're probably trying to help, but you're being a jerk doing it. The first post might have been warranted, the second one is derailing a FS thread

im in west palm beach, i know the kid with the probe, i used to go to the meets on mondays at SA.

Godspeed, i didnt mean to come off as a jerk and i was unaware of a FS thread. I think leatherface24 setup is awesome and my hat is off to him for his innovation spirit, however to warrant the gains, a valid dyno is needed as to not to mislead others who may want to do this in the future.

Btw tyson, I live in lauderhill and think i have seen your car before in previous meets.

okay...and take a look at the torque curves... :idea:

I'll make it more clear for the less intelligent....

http://boostedmiata.com/dynos/probeg...a%20torque.jpg

look how that dyno added in all the extra torque past 5.5K :jerkit:

Maybe your friend with teh Probe GT needs to fix his boost issues the occurred between dynos before calling BS on the first dyno.

It's all freaking relative. He made more TQ on the dynojet....but less HP....it's apparent why...go die.

Im going to head back to where I did my first Dyno run so theres more of a definitive idea of what the cars doing now. at least i can say i bested Flyin Miatas 228rwhp max lol

On a side note, I have my new turbo and all the fittings and lines and flanges and all that jazz. The new manifold should be bitchin and help me out with spool. The EWG should help that too. I wont have it all done until next month, hopefully the first week. We'll see

My bad...this isn't the FS thread, he's got one by almost the same name.

Damn right, he's done a LOT with a turbo most people write off as worthless. I used to be in that crowd.

I think Brainy addressed the dyno part...

You need brake fluid.

He's getting my Hydra. :)

A fact I will not let you forget right?

At least it's staying in the "family". I bought your old car now you're buying the brain to it. lol

So MAF is being deleted right?

Also why is the turboe on fire in one of the pics? Sorry I can't tell what's going on..

yes on teh maf and the exhaust housing needed to be heated up in order to weld the steel flange to the to it

what a triangle of love going on! hehe

i have Erics old intercooler, pipeing, BOV and turbo.....which i assume to be yours once before! :greddy:

indeed. this is just an orgy of miata goodness

Please tell us you ported the turbine inlet flange at the bottom of that beautiful merge. And made some kind of brace so the whole thing doesn't break off the head when it resonates at xxxx rpm.

I like how 1&4 and 2&3 are paired.

MMMM yummy manifold.

I hate you. Not really but I think it's so awesome to see DIY that looks good, I wish I had the skill and shop to be doing that. Great work man!

No brace and yes to the porting. Theres no reason for the brace. Everythings 304 SS including teh flange and all the elbows are Schedual 10. Its extremely strong

:inout:

lol itll be fine. If it cracks, it gets fixed. There are 6 other mani's similar to this that Rick has built and none of them have ever cracked.

I'd think you would have a lot to benefit by adding a mild steel brace for the little work it takes. The mild steel would allow some movement for expansion/contraction but ease the load on the runners when it comes to the harsh jarring from the cantilevered load. I created a brace using two pieces of small square mild steel tubing on each end with a solid rod in the middle, sleeved by the tubing. Cheap insurance?

That's amazing. Is this your own personal shop, or is that your business?
