Default pnpd, clipped and ewg vf22

posted something similar in the 2.0 forum but just wondering what you all think i will get out of this setup:

deadbolt vf22 (pnpd clipped ceramic coated)
external wastegate
water/alky injection
modded stock injectors
stock topmount
utec tuned pretty agressively by dan at harmon motive.

post any ideas, predictions, and sugestions. really lookin to max out the vf22
and run competitive times with the gadiel tuned vf39

I wouldn't have bothered to modify an IHI but that's just me. The only clipped turbo I had I hated; the increased lag wasn't worth it. I would just go 18G or 20G for not too much more.

I don't think you have much response because people are looking for results (track times, dyno numbers, etc). Most people wanting suggestions post them in the 2.0/2.5 forums, then post here with their results.

The biggest problem with the vf22's is if you start making some decent power the compressor wheel will start to lose blades. This is because of the high shaft speeds require to flow the amount of air you need.

I think the guy above is right also - maybe the wrong place?

Well, I can show you what I made without WI. This is the dyno sheet from my set-up with a 3rd gear pull at 1.2 bar (17.4psi) and a very safe AFR. My #s are very similar to tuned STis w/ TBE and UTEC on this dyno.
http://www.iconwerx.com:16080/wrx/dyno_sheet_low.jpg

vf22 (ported and clipped from deadbolt)
STi Pinks / Fuel pump
UTEC
AVO Topmount
Borla Headers
TBE (w/cat)

Now, add more boost (say 22+lbs) and throw in water/alcohol injection and I suspect you would hit 300whp easy. The WI would keep you running clean and lean w/o knock or dangerously high EGTs.

I think you should worry more about the tranny holding up than the vf22 throwing blades. With as many people using (and abusing) vf22s on these boards I would expect a lot more occurances than there have been. I had a heavily modded Galant VR4 for 10 years (with a td05 16G) and the DSM boards were full of people warning about the 16Gs failing. Mine started burning oil after 8 years/50,000 miles.

Also, and I don't see the need for an external wastegate with a vf22. If you were pushing HUGE boost and were getting massive boost creap then I would consider it. But I can't imagine it is worth the extra time/money/fabrication that would be required.

just skip the IHI line and get a monster 16g you will be alot happier and you could upgrade and rebiuld the 16g while the VF22 your SOL. Also if you buy from deadbolt you free lifetime rebiulds! thats the major selling point right there.

As I said, you can make more power than that on a non-modded VF22 all day long. That power is only 103mph ish traps. I've run 106+ also on 17psi with a VF22.

If you had the money for a worked VF22+ex WG, you have more than enough to buy a FP green or any other real turbo.

I think the best thing about the IHI's is they are cheap, bolt straight on, and make decent power with minimal lag. But keep in mind they are stock turbos.

ya well im pretty set on a vf22. if i were to go bigger i would want to go BIGGER like a green but thats too much lag for me.

anyways i posted this here to see what kind of numbers people think i would get. i posted something similar in the 2.0t forum to see what people thought of the ewg on a vf22.

For not much more? A vf22 is a steal when it comes to price, it got mine for $550 shipped brand new. 18g with lines is gonna cost you around $1,000... that's almost twice as much. (but of course, i'd get the 18g over the vf22 as well if i had the $ to do so)

never got any solid results out of my car... on pump i managed a 13.01 @ 105 with the stupid utec controlling boost (i.e. 14psi in 1st, 18 in the 3rd.. i've never seen something "control" boost so crudely). Slowly but surely my car was dying and dying and dying, losing compression apparently, as my traps would go down and down (105 not even being that high, tuned by one of the guys at pdx tuning initially, tuned by Jarrad). Did a compression test after i thought i blew my motor, 60psi in #4 cylinder... hope this doesnt scare you off!

(p.s., ej257 in the mail )

Clipping the wheel increases lag? I thought it was the other way around...I have a VF22, got it ported and polished for $500 before it was ever put on a car...good turbo IMO.

Clipping (removing material) from the exhaust wheel causes it to be less efficient. That means that it takes more air to move it, but at the same time it becomes less of a flow restriction. It gives you a bit more top end because the wheel doesn't inhibit flow as much, but it also causes some lag since it will take more air to get it going.

P&P & Clipping and a VF22 also voids the warrenty on a IHI of America turbo.... and deadbolt doesn't do free rebuilds of IHI's.

If it goes then your ***** outta luck.

yes clipping increases lag

No, they dont start to lose blades when you start making decent power
No, you CANt get an 18-20G for "a little more" than a VF22, try over twice the cost

Yes it would void the warranty, if there was a warranty to begin with and if you cant even spell wArranty, why the hell should we listen to you to begin with

So your lack of knowledge on how to make the UTEC work is the UTECs fault??

I have never seen a UTEC that had any boost control problems. I have however seen tons of people who had no clue how the utec actually works, blame them for their own problems

< 18PSI in 1rst. 21 in every other gear. Utec controlling things just fine.

Then you haven't been looking. Not saying that it can't control it, but there have been lots of people with similar issues (especially earlier on) using the fbc to control boost.

No wonder so many threads on this board turn to *****.

My apologies for the misspelling if you canít lead using your experience and a positive attitude, instead of the random negative comments as above, then expect your credibility as a "guru" to quickly dissipate. People on this board are quickly getting fed up with this type of abuse.

And yes there is a warranty and Jerry from Deadbolt honors it. I know from experience. Not all of us are kids on this board and most of us are here for the information not the harassment.


Have a nice day.
