365 RWHP on the dynojet

[GhostRL]

Well I got the sky strapped down since I finally worked out all the little bugs in the dejon 5027RE turbo kit.

Dejon 5027 Ball bearing turbo kit with Garrett 5027RE by Precision Turbo
Dejon Pipes + Greddy RS BOV
Dejon Boost controller
Dejon 2.75" Ceramic coated catless DP
Magnaflow 3" Exhaust
QTP 3" Stainless Electric cutout (It was CLOSED on all of these runs so the dyno would reflect street performance. Could probably gain 10hp or more up top with it open)
Fujita Intake (This HAS to go, it is way too small at 2.5" for this setup and doesnt fit the dejon correctly, going to a 3" dejon intake to match)
RPI Intercooler
Westers Base tune to eliminate ecm nannys and up to 7000 rpm limiter with adjusted fueling through HPTuners by me

93 OCTANE PUMP GAS!

SAE Numbers
21 Psi - 333 RWHP - 301 RWTQ
23 Psi - 341 RWHP - 341 RWTQ
25 Psi - 365 RWHP - 352 RWTQ


The 23 and 25 psi runs stopped early at 5600 rpms, the fuel isn't there on the current tune (I tuned it at 21 psi) for it to pull all the way to redline, But I imagine at 25 psi she stands to pull to close to 400rwhp on PUMP GAS if the graph continues like the 21psi pull was, perfect nice and smooth. It was HOT HOT HOT outside, 92-95 degrees on each pull ambient and 30% humidity. I'll post the sheet tonight when I get home from my parents' house.


Lookout hahn racecraft, you're about to lose the quickest 4cyl kappa title when I can get back to the strip and put some race gas in her

Does that turbo just bolt in or do you replace the exahust manifold as well?

How much did you pay for the turbo and downpipe?

I am very interested. I already have the rest.

[GhostRL]

It took me almost three 8 hour days to do all the work myself and I am a well-experienced shop mechanic with a complete set of tools, a bay, and a lift. I could probably do it again in half that time but the learning curve is a B. Dejon sells the parts as a kit its not just the turbo, you need water lines, turbo manifold adapter, oil lines, water lines, adapters, elbows, stuff to fit the new turbo etc etc etc. They aren't a sponsor here so I can't get into prices but you're welcome to pm me.

[BSRL]

Nice job! Can't wait to see some track numbers.

[xxdjfate76xx]

wow, i hope u have the tires to support those numbers! lol good job! videos please!!!!!

[OptimalZ06]

Do you have any video of this car running (in car, take off, etc...)? I'm interested in seeing what a higher power sky sounds like.

[GhostRL]

Somebody videod it on the dyno, I'll see if I can get it from him. It sounds mean through the magnaflow, but overall tone isn't much diff then a stock turbo with a magnaflow and no cat.

Is removing the cats required on these cars for turbo modifications? This is my turbo ignorance attacking me again, but would a turbo not benefit from a high flow cat (because it provides back pressure)?

[GhostRL]

The computer doesn't see boost past 22.5psi or so so once it hits that wall it goes bonkers because it doesnt automatically add fuel... I've added fuel manually through HPTuners tables but apparently not enough quite yet. She'll sure get up and go through

EDIT: The air/fuel on the sheet is wrong, crappy tailpipe afr. My UEGO read a consistent 12.4:1, right where it was tuned at.

Awesome. I've seen some concern as far as tuning these cars go, how has HP Tuners worked with it?

Looks like there is some room for improvement on your 25psi tune (just like you stated). Looking at the dyno sheet its real unsmooth at 23 and 25psi, but 21psi looks DANG good. I bet once you get the tune worked on @ 25PSI it's going to be knocking very closely to 380-390rwhp, and open that cutout and you may hit that 400 mark!

And look at that torque to boot! This makes me feel better about the sky, you'll have to keep us updated on how the engine handles the extra power.

Back pressure is the enemy. Period.

When you're running a large turbo/lots of boost, the EGTs tend to melt/destroy most cats... not that it can't be done, but I have no use for a cat on my car and it's certainly easier to manuever in the engine bay without one in the way.

Learn something new everyday. I knew that cats and turbo's didn't go well together, but I wasn't sure. Now I know .

Keep us updated Ghost, Hope you get to 400 .

P.S: Just noticed, you were born 1 year to the day before me. Thanks for serving

waiting for a vid or something.

[RPIpower]

Congratz! Welcome to the 300whp+ club. You're catching up to me!

[bun1t]

If they package this kit with a tune, I will buy one.

[bun1t]

I called Dejon and I didn't really like what I heard. They said a tune is recommended but not required. A significantly bigger turbo will need a retune no matter what. I suspect some blown engines in the future

[shabby]

Our ecm will keep the airfuel ratio the same as stock, so even if you add a bigger turbo it'll still run at stockish afr, thats why dejon said it wasnt required. But since theres no software that has full control of the ecm its pretty pointless going with a bigger turbo since you wont get the most out of it, ghostrl could still pick up some more hp but the hptuner software is pretty limited.

Do you know this for a fact? Have you looked at dyno's supporting that statement?

I'm all over upping the turbo but it looks like I'll have to wait until the tuning options catch up.

actually, there is proof here and there. With a wideband 02 stock, and a "too smart for its own good" ECU, not to mention a fuel system that seems to support 400+ whp, lots of redlines/gxp's with varying mod levels are all around the same afr, tuned or not. Bald turbo freak on the sol forum was one of the first to swap to a larger turbo, and he initially had it running on the stock ecu. he then tinkered it with whatever hptuners could allow him. I think now he's using a combo of the westers tune, and his own. But you are correct in the statement that the tuning side of things needs to catch up to everything else.

Good to know its possible but I would still want a full tune. 400whp would keep me happy for awhile. That reminds me, how much hp can the 2.0L's handle?

i remember a while back some crazy guy wanted to find out for himself. If I recall correctly, he threw in a 300 shot and it cracked the head. Then again, thinking back on that, a 300 shot after SEVERAL WOT runs with no tune or supporting mods for it on the stock block........ONLY a cracked head is pretty good. He had tried i think a 125 shot and 200 shot and the engine held just fine. Goodluck finding that thread though.

I'm happy with mine for the time being on the stock turbo (dyno numbers in sig)
