Custom dyno tuning

This would be based on using the stock turbo, and 93 pump. Just trying to get a ballpark idea of what to realistically expect.

 

390-410 whp, 400-420 wtq ballpark playa, that 2.3 will pump out some healthy torque. If I were you and was dropping that much into a stroker, I would look into a 3065 sized turbo.

 

For the sake of not trying to sound stupid (forgive me, as this is my first turbo car), but on top of the modifications I've already listed, what else would be required to hit 500+ whp? I would assume at this stage then that the stock turbo would have to go. What else would you suggest?

EDIT: I see you've mentioned upgrading the turbo. Going that route, could I hit my target mark?

 

Which dyno or who's dyno? Who is doing the tuning? All dynos read differently and I could give you a ball park figure and then you dyno on a Mustang (that actually reads like a Mustang and not a Dyno Jet) and my guess would be off. On most Dyno Jets and/or Dyno Flash's DD you should hit very close to 400whp and like freaking 480-500wtq. I mean that would be my best guess because I know of only one other EVO IX that dynoed with similiar mods as you and that is what he put down (minus two cams, he dynoed with only one cam).

 

they dont have 280's.

only 272's which i got recently and waiting to put them on.

 

A 50 trim or similiar sized turbo, or a GT35R. I don't think a 20G-9LT would get you 500whp, but I must admit I would be extremely interested to see the results

 

I understand your points. I don't know which dyno to tell you the truth. I haven't even purchased these mods yet. I guess what I'm really trying to say is, what would I have to do to get the car in the ballpark of 500whp? Given the mods I've already listed, and now, a larger turbo, would it be reasonable to expect that kind of output?

BTW, I realize that in my endeavour to reach these numbers, alot of other things will need to be rebuilt or strengthened like the transmission, axles, transfer case, brakes, etc. Just hoping to see if someone could give me any other pointers on how to proceed engine-wise.

Thanks.

 

Understood. Thank you.

BTW, if anyone wishes to adjust or supplement the list of mods I have posted, please feel free to do so. You guys have far more experience than I do when it comes to this platform, so I'm here to learn.

 

Its a wierd kind of setup IMO, what exactly are your goals? Do you want a road-race car or fun daily driver, etc.

This setup will pick up a lot of tq.

 

Thinking primarily of road race events, possibly some time attack as well. I've got a couple of years anyway.. as soon as the wife finishes her doctorates, I can buy another DD, and then turn the EVO into a dedicated track machine.

 

there's been several proven combos to get to where you want to go, of course each one has it's own level of risk of self destruction. Basically, you can get there cheap (relatively speaking) and have a higher risk of blowing up, or you can get there more expensively and mimimize the risk. Here's one of the proven and cheaper ways to get to 500 whp that has been chosen by many on evom.

50 trim turbo kit (AMS's kit would be my preference)
780/880 cc injectors
Walbro fuel pump
GSC S1 cams
ARP head studs
full 3' exhaust
meth injection kit
boost controller
custom tuning of stock ECU

This combo should net a solid 420 whp on a dynojet on 93 octane, and touch 500 whp with the meth injection on 93 octane. All on stock block and stock head. You'll probably want to put some money aside for gauges, a wide band, etc.

But there are multiple avenues to get to 500 whp.

 

Do away with the AFC, ARC induction box, DC Sports exhaust manifold, AMS twin rail intake manifold, Greddy metal headgasket, ARP Connecting rod bolts.

Just use the stock ecu for tuning so you wont need the afc.

If you get a turbo kit you will need to get an intake thats matched to it. So no need for the arc intake. The turbo kit will come with a manifold so no need for the dc header.

Just run a stock ported intake manifold.

Use a cometic head gasket. Or a stock new one.

The rods will already come with good rod bolts.

I would get a gt35r kit. Buschur or AMS.
Definitely get some bigger injectors. Probably 880cc's

And a meth kit!

Then your on your way to over 500whp

Swift and Dubble ^^^ thanks for your suggestions.

To Dubble, I don't want to go cheap and compromise integrity. The car would be built to endure road racing, so building up the stock internals (along with t-case, diff, and tranny) would definitely be a priority.

 

damn its kinda funny, the other day i was thinking about going stroker without a turbo kit but i had never seen anyone else with it so i figured it was stupid. I'd love to see the results. That would be some crazy torque and spool!!! Does anyone know anyone else who has done this?

 

Check it out, Imma hit ur mark and pass it with probably LESS Mods.

Here I go.

Buschur Racing = BR (incase u dont know)

AEM EMS
BR Full 3'' Exhaust
BR Intake w/ Filter
BR Delux UICP W/ TiAL BOV
BR LICP
1000cc Injectors
BR Upgraded Walbro Fuel Pump
BR 2.3L Stroker
BR Stage 3 Head
BR GT35r Kit
HKS Electronic Boost Controller
HKS or BR Ingition Booster (HKS DLii I believe its called)
ARP Headstuds
Some sort of High Performance Clutch

Meth Injection!!!

Tune by Buschur Racing.

Theres 600+ hp

And if u wanna really do it up u can get an AMS VSR Intake Manifold, and some Cams, 280 for your car since you have n IX. GSC or Cosworth..Whichever you want.
