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.

15psi.
on ewg spring no mbc.

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.

18psi

iTrader: (76)

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
Did we mention he's on his 11'th transmission?

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

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

is that some kind of bad *** 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?

Faeflora

iTrader: (2)

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

18psi

iTrader: (76)

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.

Faeflora

iTrader: (2)

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

18psi

iTrader: (76)

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