vf28 Vs vf22

[fbssub1]

pros and cons here guys, have a vf 22 for sale been offered a vf28 as a swap, I was thinking step backwards to the vf 28, but your guys thoughts

[Guest]

Had both but never actually ran the vf22, the vf28 is a hell of a lot smaller than the 22 so runs out of puff at 200kw, did with my set up, vf 22 obviously goes a lot higher.

In defense of the vf28 it came on pretty quickly around 3500 revs on my motor running 20 psi.

Any vf turbo is an upgrade to a vf22 unless running 550+cc inj plus other fuel mods, computer, and tune, etc

[speedfreak]

have no experience with a 22, but have a 28 on the rally car, dynoed at 242 at 15PSI (limited by MAP sensor/computer)

EDIT - Sorry 242 HP, on rally car with restrictor..... sorry for confusion

242kw???? seriously?

[sultan]

180kw

i now of one VF28 that has 250kw but thats with NOS and link

[WRXONP]

When I ran vf22 it was hitting 20psi around 4k give or take - vf23 was hitting 20psi around 3200 if I remember correctly

Vf22 will dick all over a vf28 cos they run out of puff around 6k

[funkytown]

all vfs run out of puff around 6k.

realistically the difference between a 28 and 22 is actually quite minimal.

There isn't much call for 8000rpm driving to the dairy. Is it for a race car or a daily driver?

[WRXONP]

i wouldnt say a p20 rear housing runs out of puf at 6k - it all depends on other mods done to the car aswell

have a look at this

[Guest]

VF24/28/29 are all relatively similar are they not and run P18 housing? Never seen a dyno over 200kw with any of them tbh. 240kw sounds out of reach on any VF but Im no turbo expert. Could be a happy dyno?

[WRXONP]

that turbo info page is a load of crap and should be deleted - a vf22 at 25 psi doing 450 hp?? should be a tui billboard more than anything else

[Guest]

I think it must mean 450hp at the flywheel? Think that works out to an almost acheivable figure.

ultimately the decision is obviously yours man, u need to ask yourself what you want out of your car!! do u want to be thrown back in the seat or do you wnat to be able to flick threw the gears quickly? Each of the turbos has its pros and cons as im sure others will agree.

Everybody seems to talk about h.p (what we love to call the wank factor) Ok h.p is obviously important for bragging rights, but what about how much torque the car puts out?? thats what throws you back in the seat and holds you there, ask yourself what you will use the car for and do your research into what turbo is going to provide you with the needs to achieve your goals, remember hp isnt everything!!

sorry 242 HP which is 183kw, sorry for the confusion

everyone saying the vf22 is very laggy, yeah it is compare to the vf28. in my case they are very both good turbo... in the end i would prefer the vf22 for the better top end as i dont race around cones on a parking lot events but then i would prefer a TD04 for that, which re pretty good. i got rid of my vf22 for a VF37 then got a IHI RX6 which is kinda off topic now?

over all like other people are asking what your intention with your car?

i had my vf22 dyno with possum link years ago and got 220kw@18psi the injectors was maxing out

what injectors where you running, looking to do a rebuild on a v8 sti motor, strip it down to case and crank, add some I rods and some 92.5 forges, ported and polished v5 sti heads and go from there, got 565 side feed for it atm but may look at 800cc injectors

sorry it was my old 99RA running on yellow injectors

+1 Grade A comment...Torque is what ya require Oh Yeah!!...The Phrase ,"Horses for courses "springs to mind.

Also , Should i say Usually,...Race application engines with turbos are best kept to a specific rev range to get the most out of the setup/engine/turbo combo.

Maxing out to the 8000 rpm Limiter is just stupid :, The power peak has already been passed way back down the Rpm range. Therefore gearboxes have been fitted to allow return to this "power zone"
