Hey guys.


aggain a stupid question from me , but i'll hope someone can help.

within 2/3 weeks my new engine will finally be finished
and be tuned on a engine-dyno

new i have this weird question.
i have sitting here a brand new GT4088r turbo , and a sc61
which will both be used in a later on this engine.

but since this engine cost me a little fortune of dollars.
i first like to break in the engine with a smaller turbo
for some reason i suspose its a bad idea to throw over 600+ hp on the crank right away because :

evrey single parts on thsi engine is 200% brand new. so it might break in yet .. for the bearing clearance etc etc .... ( or i'm talking BS ? )

and i need to get used to the power , since i always drove it quite stock and later with a t67 that never did any good . i dont think i can handle 600+ hp right away LOL. yeah stupid ... but i only live once !

so i decited to start learn to drive a high(er) hp car first , and decited to go with a t3/t4 50 trim first.

anyway , my first goal is to drive a few 1000 miles with a small turbo and
conversative tuned engine , so i.e i dont like more hp than 300 for the beginning.

my plan is to throw a 50 trim t04s .60A/R - stage3 76mm t31 .82 A/R on it.
would this be a great turbo to learn my self tune the power fc and datalogit properly + learn to deal with a higher hp mr2 + break in the engine in first?

or would you guys say , throw the sc61 on , and just lower the boost ?
or maybe even throw the gt4088r on ...dont care about the lag . and it will be fine ?

let me knwo what you guys think about all this weird idea's i have.

i just like to be sure i can handle the power ... and the engine wont blow that fast .

Just put the big damn turbo on lol, thats what a boost controller is for, and being careful on the throttle.

As far as i know, only the rings actually need running in, the bearings run on the oil clearance not on the metal so theres nothing to run in, if the clearances are correct, itll be fine.

Id be more concerned about running those rings in for a few hundred miles before having it tuned, but I have heard of plenty of people dyno tuning a brand new engine with no problems in the past, not many do tho, but not many have an engine dyno to tune on either!

I wouldn't think it would matter what turbo you broke it in on, so I wouldn't waste my time trynig to make one turbo work, then turning around to make another one work. Besides, you seem like you are worried that as soon as you start the car the wheels will suddenly see 600RWHP and you will be spinning all the way to the grocery store :rolleyes: . Dont stomp on the gas and keep the boost down and I wouldn't think it would be a problem.

Good luck! ost updates when you can!

its more like .... when you have the power ..you#ll use it
and since i drive the car evreyday to my work ..at 4 -> 5 am
its alwasy quiet on the highway , and in holland its still pretty easy to drive
120+ mph. then. no police or highway patrol in many miles over here.

i know i will use the power if i got it ... thats why i allready said . in safty of my self
wouldnt it be better to start learn to deal with 300 whp .. which is allready twice the power than most fast cars on our higways ;) ... get it.

and the other thing that concercend me is the engine ... but it seems that it will handle hte power after the ringslands are runt in.. runnigt in... runnigd in... whatever you write it :D

Or better yet, put it in a big box, and ship it to me, I'll drive it around for you for a while and make sure everything's ok with it. ;)

This bit concerns me. You have spent a huge amount of money on the engine and ancilliaries but you're planning to scimp on by far the most important part of the process. The tune is the thing that will keep the engine alive and make it perform optimally. Unless you are very experienced and have access to a dyno, get the car tuned by a specialist.

It doesn't matter how good an engine build you have if it is setup to make 600+hp and the tune isn't right it only take a tiny period of detonation to turn the engine into a useless pile of metal.

Or we could work out a trade with your SC61 for my SC44 60 trim, and you can start off with that :)

we dont have any good tuner in the netherands.
the few i know are all idiots , and never heard op apexi power FC's before ...
maybe 2 ever heard about the dta management ... but tuning a ems properly if far beyond there quality's .... most of them never even heard of a WB afr .

so i really have to do it with my buddy ... ( pfeiffer44 on this board )





@ Tysaxon.

considering it ..... not sure if i will trade my sc61 , since i whas planning to use this turbo for daily , the 50 tri idea i had ... whas pretty much using a sc34 , sc50 or sc44 before ;) thats why i had intrest for youre sc44 :D ..

My thoughts exactly. Even a 50trim will put you well over 300, so take off your skirt and slap on the SC61... if that'll be your daily turbo. A peak at the dyno registry shows a 2L SC61 car needing 5500 rpm to hit 300whp @ 19psi so you'll probably have the most fun by keeping the boost up a bit and shift at 5500, or maybe 15 and shift by 6-6500 or whatever.

I made [email protected]+ @16psi with a 61mm turbo last week. I havent posted about yet though. If you have cams and other ve mods I would leave the 50 trim alone.

Just a camera every 5 miles that fotographs you, or some sneaky cop bastards with cameras hidden in bushes.

Where do you live? Texel??? whaha

Youre wrong. Try Paul from Beek Autoracing. (www.beekautoracing.com or nl)

All he does is tune race cars for the track and stuff.

He tuned my EMS with a wide band. Tuned my ct26 to 230 rwhp and 275ft-lbs of torque at 19 psi. I dont even have a knock sensor. He knows the limits.
Did not have any problems with that tune. And i gave me car hell everyday.

^^Did you pay him for *tuning* it to : 230 rwhp @ 19psi????

Lawrence
Why?

I can tell you it doesnt make as much torque at 16 psi as it does at 19 mate.
I also had a lower boost mode at 14, 15 psi.

The story that it just cant make more power after 15 psi is stierenstront. (dutch for bullsh*t)
