How to get the EVO3 turbo to 350hp

I don't back down from anybody. Any moderator that thinks they get my respect because they have a different tag under their name is wrong. It takes a lot more to earn my respect.

Well over the next few days you will have some time to think about how you can earn the respect of the other members here. Enjoy your vacation.

I don't give a shit about your respect. I give a shit that you follow the rules which you don't. You're the one trying to be another internet togh guy.

your gonna need more then just an evo 16g if you want to make 350 at the wheels on pump gas. i have a 20g and just about every supporting mod, and i just dynoed at 300 to the wheels on 18 psi and 93 octane. peak power would have been a bit higher, but iv got boost creep to 25 psi, and had to let off every time it spiked past 20. it made 300 awhp at 4000 rpm which is barely into the powerband of my cams, past there the power curve was up and down every 700 rpm or so, cause we had to keep letting off to keep it under 20.

i doubt i can make more then 350 at the wheels on my set up on pump gas. i certainly could if i put 116 octane in it and turned the boost back up to 28 psi, but you arent gonna be able to push a 16g that far and if you could it wouldnt make as much power as my 20g does at that boost.
if you really want 350 awhp out of that turbo, your gonna need to run boost around 25psi, on race fuel, and probally still need nitrous to see above that number. but a number is pretty meaningles, your car could run low 12s on your turbo with well less then 350 whp. actuall speed is alot more then just your horsepower number.

SlowboyRacing made 400Whp on there 1g gst a while back, give them a call and ask how they did it.

You are wrong. He does not need to make 350 all wheel horsepower because he drives a FWD car. And he won't need nitrous. And he didn't say he wanted to run 12's. He said he wanted 35+ horsepower. Stick to your 20g and let those of us who have owned and dynoed a evo3 16g talk about it.

In fact I'm suprised Josh (shapegsx) has not dropped a line. He has trapped 118 on a evo3 16g in a awd 2nd gen...if that doesn't say 350+ at the wheels to you then you are not familiar with the subject.

As much as everyone would love to build up a 2.3 liter just to make 350 at the wheels on an evo3 turbo...not needed.

True that but it will still get him there, since he just asked what would get him there

hahahaha, a vacation, that is so nice of you man. hahaha. how you been nick? it's been a long ass time, i think it was the Ocean City meet like 3 years ago. .

 

[98spydert]

I'll throw together a list that will get damn close if not there cause I'm bored

1G TB and manifold port matched to the head
ported turbo, manifold
O2 eliminator turbo back
unreistrictive filter, intake, and I/C pipes and some sort of bov that will hold
FMIC
FP2, 272, or crower equiv cams
255 pump, 650s, AFPR
Water/meth injection
fuel managment
Clutch/flywheel

And of course the little stuff, mbc, gauges, blah blah. That should take a evo316g on pump right up there around 350whp

 

[xcz504d]

Theres a guy locally that pushed 28 psi through a 16g, he had it laying around, threw it on his car, car felt like it had more than 350 whp, but the turbo lasted about 2 days of abuse before shaft play set in so bad that... well... lets just say that it wasnt the best way to clip the turbo...

Step one Cometic head gasket,step two get some arp head bolts whle their working on the car. Step three would be to seriously plan out every possible avenue to reach you'r desiered driving goal or inteded use for the car , and p.s hears a link for you .

http://www.dsmtuners.com/tuning-guide/2gturbo/stage1power.php

If you scroll out of this section you can clearly see theirs more lists of things that would help you get to you'r goals wich are even tailored to you'r car ,and they have some handy info to go with it too.

 

[ikickuintheball]

I think you'll need what revolution said, a set of FP1's (or HKS 264/264's if you have the money), DSMlink, 660's, 3" turbo back exhaust, a decent fmic (doesn't need to be the width of your car ), fidanza flywheel, act 2600, c16, and a load of dyno time with dsmlink with someone who know what they're doing. Good luck!

25psi on an evo3? Tell me what kind of crack you're feeding yours and I'll feed it to my 20g.

Same crack my 16G smokes, apparently.

When I race at the track, I run 30psi spikes that settle down to 24 to 25psi, depending on how cold it is.

Hey shape, what mods do you have on your car? Your profile is kinda vague, I'm trying to see whether i should buy 550s or 660s for my evo3, are 550s really enough for this turbo?

 

[sbiggi]

I know two people that made 300 whp up here in Denver at 5800 ft above sea level. Not corrected numbers either.

You should be able to hit 350 or very close to it at sea level no problem.

My brother put down 264 whp @ 18 psi uncorrected up here in denver.
3" GM Maf, 680cc injectors, Frontmount, 3" turbo back with highflow cat, and 264/272 cams.

This weekend I fully expect to make 300whp with the same mods plus a custom chip tuned by my self and 25 psi. That should be 40lbs/min airflow to get those numbers at this altitude. RMDSM Hp Competition is this weekend and you can see the results for your self online at rmdsm.org

Not if you're trying to put down the power that shape does. Go with 650s, at least you know you won't be on the fence with them.

 

[ShapeGSX]

550s are definitely not enough. I used to have 550s with my small 16G. I maxed them out with the Evo.

I have HKS 264I/272E cams, an 18" Griffen FMIC, custom 2.5" IC pipes, 3" exhaust, DSMLink, 660s, 1G head/intake manifold (though I don't feel it makes much of a difference over the 2G stuff), 6-bolt block with 2G pistons, K&N FIPK, Walbro 255, Aeromotive FPR, 4 spider gear center diff, intercooler sprayer, 1G BOV with Gus mod, etc...

 

[joemathews]

Shape, was your 2g full weight when you trapped 118 and broke into the 11s on this turbo? Those are some damn impressive numbers--I'd be ecstatic over low 12s when my turbo is maxed out. I bought Travis's (KPWSerpiente) Evo16g and got it on the car a few weeks ago.

Looking forward to the RMDSM dyno numbers from this weekend....

And finally, with regard to whether 550s or 650s+ will be necessary to put down 350 whp, the safer bet would be 650s+. However, Evo 8 560s are fairly well matched to the airflow of the Evo16g...

(*pulled from AutomotiveForums.com E/T/L forum, quote from Kevin Jewer*) Ran some quick numbers guys, since we should all know now that fuel requirements correlate directly with airflow. These are for 560 injectors, a fairly "new" size, so I thought it would be fun to take a look.

Using pump gas (assumed Specific Gravity of .76) and target AFR of 11:1, a common pump gas AFR, 560s will support 41 lbs/min. More than small/big 16Gs put out, and just about on par with what most poeple get out of EVO 16Gs.

Same scenario on race gas (sunoco NOS Supreme 117 octane assumed, Specific Gravity of .724), and target AFR of 12:1, 43 lbs/min.

Notice that the numbers are not all that different. The reason is that while you are using less fuel at the leaner 12:1 AFR, you are also getting less mass of fuel per unit volume since the Specific Gravity (Density expressed as a ratio to water) is lower Keeping fuel constant, you can see how much leaning out helps with getting more out of your injector (and pump). At 12.5:1 you're good to 45 lbs/min, 20G territory. And so on...

 

[ShapeGSX]

Yes, my car was at stock weight. Always has been. 3150lbs without me in it. 3315 with me in it.

Sure, 560s are well suited to an Evo 16G, if you don't have upgraded cams, an upgraded exhaust, intercooler, IC pipes, etc...

But with all the mods I had, at 20psi, I was already well over 100% injector duty cycle with the 550s. With the 660s, I am now in the mid 80s.

 

[98spydert]

550s are definitely not enough. I used to have 550s with my small 16G. I maxed them out with the Evo.

Did you use a 1G head and if not did you port match the 1G manifold to your 2G head?

 

[ShapeGSX]

Did you use a 1G head and if not did you port match the 1G manifold to your 2G head?

Yes, I used a 1G head. That is why it says "1G head."

 

[DSM_GSX4life]

how much harder if at all would it be to get 350 wheel power on a ported big 16g??

 

[98spydert]

Yes, I used a 1G head. That is why it says "1G head."

haha I'm a dumb ass I thought it said "1G throttle body/intake manifold" *sigh*

 

[madracer247@aol]

Wow all these things you are listing i have, i hope i lay down 350 to the wheels ok thx guys....
