just got back from the dyno
 

im a little disappointed in the numbers but i am scared to try to push the completely stock EGT BP. how much further can i expect to push the stock rods before they decide to leave my block? rev limit is set to 7300

edit: im sure specs would be nice...
95 EGT block
evo3 big 16g turbo
ebay(actual dimentions) 19x7.25x3.5 in and out tube and fin fmic
custom 4:1 exhaust manifold made from an EGT stock header manifols that was cut up
2.5" turbo back exhaust, no cat 2 cherry bombs.
38mm open dump waste gate
gutted vics manifold

i have an msq of pull 2 and pull 4 that ill upload as soon as i get it off my laptop

Wow dude, you've just taken a 20 second 1/4 car down to like the 12s and you're disappointed???

Stock rods supposedly snap around 250hp area.

That thing HAS to be a crazy son of a bitch!!!

Dynojet. That's like 80HP on a Mustang. LOL.

JK. Good numbers.

I bet that's fun :)

What was your boost level for these pulls? Pics of setup or link to a build thread? I'll be tossing my Evo3 setup on the dyno in the next couple of months so I'm curious.

nice #'s

FYI My 5 spd and rods both crapped out at 225 rwhp with street/autox driving.

Uh how mich boost is that

15psi.
on ewg spring no mbc.
with 15* at peak slowly tapering up.

this car hauls like a raped ape

^what he said. lol msq attached

yay gratzi

turn to 10psi or expect blowage

Y torque fail at life after peak? Tiny intake manifold?

if that block uses the same rods as the BP, then you're at the upper limits.

now im worried :| its been at 15psi for over a year as my daily with drag strip almost every wednesday and street fun every weekend... i beat the crap out of this thing... ill start looking for rods and pistons...

its an EGT vics manifold that has had the upper section gutted into a plenum. seemed large to me but the lower section/runners that go into the head are still stock.

With your torque and horsepower tapering off like that you don't need to push it to 7300rpm. No need to be hard on the motor.

I told him exactly the same thing when we tuned it: its at the limit.
And yet he's been raping face for over a year on it, absolutely beating on it daily, and its still kickin like a champ.

Must be a failflora block:D
Did we mention he's on his 11'th transmission?:giggle:

I think the biggest bottleneck at this point is the teeny 2.5" exhaust

I'll take "thread titles never posted by Faeflora for $1000", Alex.

i know... im fighting the urge for new wastegate springs...

is that some kind of bad ass aftermarket stuff? i mean its gotta be better than my junkyard EGT motor that had 130k on it before i started boosting it...

sadly lucky number 11 is starting to have low RPM shift issues... lucky number 12 is coming soon...

gettin a raise at work... might be 3" after the down pipe very soon or should i go bigger?

Big and short as possible DP and exhaust.

If you ever build your motor you will not want to rebuild your DP and exhaust too. Once upon a time I thoght 3" was big. Yes there is significant benefit to bigger

Except he's running an evo16g.
He will be well past its efficiency with anything bigger than 3", and has even less room to work with than we do.


Just do a smooth taper to 3" as soon as possible on the downpipe and run the rest 3" JT. I think it should get the job done just fine.

But before anything else, your next mod should be h-beam rods. No ifs ands or buts about it.

That's not my point. I mean if he decides to go to a bigger turbo in the future there are big spool advantages.

It also doesn't cost too much more at all

bigger turbo is going onto his 1600lbs FE3 powered spitfire.
in the form of a big a$$ holset.

winning

That's pretty impressive. Nice.

i cant add too much more power... already had to re weld the drivers side frame rail where it has separated from launching too many times

hear hear

HEARKEN FOR WE ARE IN THE PRESENCE OF A GOD

btw i can help you with your frame rail

easy there mere mortal...one does not ask to help god...lol..you can help if you wanna build me a tube front end...

i didnt notice it til i left the drop light under the car... the drivers side strut towrs was pulling away from the fire wall too so i also fixed that... now the passenger side is separating :( i may need a new chassis soon

or just hurry the hell up and finish teh spitfire.
stop wasting time and money on this thing and direct it all toward "THE BEAST"

unnnfffff

do you know any one that does chassis fab that may be able to speed up the process?

Easy there, buckaroo!
I am sure he can help you with your frame rail there, pardner. He's the quickest draw there is back east. They call him The Sawzall Kid...

Cant you use the EGT or Protege tranny in the festiva with a BP swap??

i am using the BP EGT/protege tranny... i was using the older cable G series trannies from the 323GT/capri XR2. they all have the same internals except the cable trannies have a 3.85 final drive where the hydraulic trannies(protege/escortGT) have a 4.10. the kia sophias have a 4.35 and has the same case yet slightly slightly stronger than the pro/EGT.

a little update...got slicks on it but i still cant drive... in the right lane
https://www.miataturbo.net/attachmen...ine=1337388982

Holy crud! That's a fast box.

did you air em down enough?

2.0 '60 on slicks is pretty weak.

picked up 15whp off of my new JDM Mazda 323 GTR manifold. unknown torque gain do to my tires spinning on the dyno :( stupid light cars

https://www.miataturbo.net/attachmen...ine=1339517960

shoulda had someone sit on the front of the car lolol

What's with the crazy peaks? The spinning?

Pics of manifold?

...things so sick. I need good vidz, NOW!

its a mazda 323 gtr manifold. ill get some sand bags or some extra straps to hold the front down
http://carphotos.cardomain.com/ride_...0019_large.jpg

Hmm, never seen one. Thanks. I guess there's really no easy way for that to fit on a Miata lol

nope... goes the wrong way. but the manifold is pretty short so maybe a sharp u shaped coupler or something to that effect

finally got the dyno video

Well played :bowrofl:

I have an unhealthy desire to build a BP-powered Festiva. The only thing keeping me away is the total lack of decent tranny options :(

was that the one i traded you?
http://www.clubprotege.com/forum/sho...-manifold-pics!

im only on my 11th tranny and 13th diff... and it locked up a few weeks ago... lucky number 12 is about to go in. apparently once i get a good LSD i only have to worry about the case splitting.

yep its the one i got from you. ill be doin a better job of gasket matching and installing a hondata intake gasket once i take it off.

What stops me is I can't find a festiva for sale that I'm willing to pay $$ for!

They're always completely and totally trashed yet the seller wants top dollar.


Are there really ANY good tranny options? I was of the assumption the EGT was but I guess not?


Oh, LOL @ Dyno video. GO....waiting....waiting...waiting...FULLLLLL BOOOOST!

You need rods and e85 in your life justin. DO IT FGT

looks way laggier than it is. the run started at 1800rpm

the best tranny option is get an adapter plate and run a turbo MR2 tranny. which is dimensionally impossible in the festiva. engine+plate and trans ends up being 5" wider than the distance from frame rail to frame rail.

im working on rods fool. im gettin LSD first. taller gearing and LSD will make it a more reliable rape all on freeway rolls

f*ck YES.

call me tonight loverboyeee, luzl

:rofl:

So the LSD is what typically grenades on the tranny? Hmm..

please post more info on your car bro

I love it when the rear end grenades!

the open diff grenades. no stock lsd option. a band aid is to weld the diff pin to the carrier. i have had 3 fail so far with just the pin welded to the carrier so i have been welding a little spot in the center section of the pin so it cannot eject past the spider gears.

I mean on the street, not the dyno video.

filmed from a 350ish whp S2000 from a 60 roll. ill see if i can get my buddy to send me the link to my 12.275 1/4 mile pass

goddamn it I love you

I'd be scared as shiite to go over 75mph in a festiva. You sir...huge balls!


Awesome.:party:

dog I'm surprised this bro's balls can even fit in that little car

I have a couple crappy clips from when I was tuning it:



vs a big turbo (t70 or something) b16 civic


400whp CTS-V


another 400whp CTS-V


and another run




I have been in this car for over 20 different races, and it STILL scares the bejeezus out of me every time we go out. And I've been in my fair share of "scary" cars.
I hope JT posts up some more vids or links or something ,this car pretty much street races every single weekend and hits the strip every other wednesday.

Everyone in town knows it

forgot about the CTS-V's...that was a fun night... and to think i have an extra 20ish whp since then and the power doesnt fall like a rock at redline like it used to.

the fastest ive clocked on GPS was 163. not really by choice. a new V10 M5 wanted to run and i took a fender on him and was not willing to give it back. he let off when i hit my 7k rev limit and shot a fire ball out my bozo. i consider that a win.

please, please, please post more pics of your car. the kind of pics you'd take if you were selling it.
