Jabba IHI, Still ongoing
- Thread starter ibizacupra
- Start date
Also Bill made 286 @ the wheels at Powerstation recently. But on jabba's he was seeing a good bit more.
from what i can find out on scoob forums, the ihi vf34 is good for about 320-330hp max if tuned properly. At 300hp, you're maxing out a tt maf, and need to move up to an s4 maf or bigger. I made between 265 and 270hp at the wheels on 3 runs today, and it's running way rich at the moment just to be safe.
But ultimately its not just about numbers. This turbo is perfect for the car. It's flexible and when you want it to be its effin oh my god quick. If you go bigger than this in a 1.8t, you're just after numbers, and not a car that you want to drive.

290-300whp should be possible with the right setup. I dont know how well the cars were ran @ powerstation. But the scooby boys normally see 320bhp there, and 340bhp @ Power Engineering. So looking at it maybe jabba aint far off the mark claiming 330bhp-350bhp on there rollers. In Bills case 286bhp would show 315-330bhp @ the crank at powerstation. And anywhere from 335-355 @ power engineering. I spoke to Custardcupra today and we both said the same thing @ present on Jabba's rollers were seeing 210bhp @ the wheels with IHI we will more than likely see 300-310 @ the wheels on the same rollers with more torque and bhp futher towards a 7500rpm redline. So its still 90-100bhp @ the wheels more than what we have now. I think the majority of cars (ibiza's) with the stage3 kit mapped by jabba on there rollers will see 335-340bhp @ the crank max. I dont think 350bhp is there for the majority of us. But i am sure it will still be a handfull and more than enough for road use. When mine's done i am gonna see if i can get an Atw power run at G-Force. And one @ Well Lane just for comparrisons sake.
gearbox is FINE - autotechniks told me there is nothing wrong with it and they are just sorting out a problem with changing to 3rd from 2nd. Its just the diff that went and i knew it would.
yes i have had an evo, was not a happy bunny pulled away at 120 easily to about 145 and he just couldnt keep up.

Whats the rev limit set at on your car SPS. And have you had it on any other rollers or just Jabba's.
not sure think it might be 7500 it goes well into the 7000's if i keep it in gear too long - 1st - nope not been on any other rollers but jabbas will have to just to see - will be going on thier new rollers when they get them so will be able to see if they were a bit generous, but having water injection fitted soon when i get it re-mapped then i will be comparing RR's

I was running VF34....... not flat out either 22psi boost on my settings.
No failures? Well........
mine melted... does that count? High boost, lagged downpipe, excessive oil consumption form breather system = overheated housing.. Melt Down.
Amazingly the actual cartidge, housing, bearings & turbine were pretty good, despite the meltdown of the housing and wastegate. Woops!

Maybe you should also look at the Stealth RR dyno for mine...
Did the same power from day 1 as it did @ Jabba. 325bhp when originally done. More to power than boost levels
Madmile said:
RECENTLY! Nope! Absolutely ages ago, well into last year. Took a long time to hit print. Power Station? Erm nope! Never been there with IHI dude... you need to check your facts. Interpro... in Rabbit magazine.. yes.
What you don't see is EVERY car at Interpro faded into oblivion with really long power runs... x4 on my own motor consequetively.. EAK! Translucent turbo/manifold/downpipe on those runs... Scarey stuff.
You simply cannot compare rollers with rollers, not knowing what the actual condition of the runs were, or how other also faired on the same dyno.... Significantly different on the Interpro day as you will notice from the actual write up.

..............or tweeked
As I said, there is more to this than just boost levels (which some peeps seem fixated upon- not you btw
)All I need is a transmission which can reliably keep this power to the ground.

Yep Interpro. I dont know why i thought Powerstation. Nothing wrong with considering boost levels. As what else do us non IHI runners have to go on other than word of mouth, figures from RR'd, spec sheets and what the tuners and users say the are running at at. It was so long ago i have forgotton what it was like. (Jabba's demo car). As long as Jabba come good before the end of November i guess i will know first hand what Stage 3 IHI is like. Cheers

Interpro use similar dyno setup to Powerstation.. both which suk for 1.8T motors with high sustained load and massive heatsoak. Ever seen a PD brought to its knees on a dyno?
We did on that day.. 
I hope Jabba sort the installs out in a timely manner for you guys.
Boost levels are misleading... but overly quoted as where the power comes from. Yes it does, but not alone. (high boost no ign = low power and high EGT)
On another forum there's a post of a 26psi target boost level on a big turbo setup.. which on an otherwise stock engine makes me shudder. Will see how well it does, when its boost eventually does come in (@ 5K rpm) and how long it lasts. (26psi on stock 9.5:1 CR = EAK!)
Liams MK4 continues to run well so far as I know.
AmD mapped ones don't seem to have faired so well.... (boost related? customer hooning around related? Who knows)
I hope so as well Bill. "I hope Jabba sort the installs out in a timely manner for you guys. "
I've had enough of waiting, its time to put up or shut up for Jabba now.

True.
There loss (and yours) if it happens.
Fingers and toes crossed it all come to plan.

From that graph it appears to be 278ft lbs. The Jabba website quotes the stage 3 as 285-290 LB FT, so thats pretty close. Still 278 LB FT is still over the 270LB FT limit of the 02J gearbox that Jabba quote.
Personally, I'd always want a saftey margin.... so if I'm gonna have 290LB FT then I'd want the gearbox to be safe upto atleast 310LB FT.
I'm even a little uncomfortable with the rods which are rated at 335LB FT.... I might get them upgraded too.

Good luck finding a box which can reliably cope Ben....
Diff only helps to strengthen the diff pin failure mode... it does'nt effect the actually gears themselves stregth wise..
All down to use... Use it on track regularly and you will more than likely consume transmission components.
Did I mention quaife SUK!

Yeah apparently the standard diff is the weakest part. Sort that and the next weakest part is good for 320LB FT, but like you say, if you treat it bad then it will fail.
AFAIK the gearbox is the only as yet unsolved problem on the Ibizas, ie. no-one has found a good solution to the weak gearbox problem on an Ibiza that will be used as a daily driver.
Jabba say that the Quaife gearkit is good for over 400LB FT, but wasn't this what the Golf had (Different gearbox though) when you first got it, and you said it was horrible?
Al at Autotechniks says that he is confident that he could fit the Quaife gear kit and still retain a much nicer feel than you had on the Golf, but even if this is true it doesn't solve the high speed synchro problem.
Dog box/Race boxes are a no no for me and most other people I guess?
02M would be nice, but CAN it be done (Within reason)? Also, adds a bit of weight.
Also, as you say.... Quaife are a 'bit' slow ATM, so the gearkits may not even be an option.
I don't know much about other gearbox companies, such as Gemini etc. Do they do anything that might be worth looking at?
Bill, I see that you are having problems with your box? Do you think its just a gremlin that can be fixed, or do you think the box simply isn't adequate for your power (Any idea what its rated at?)? I hope it can be sorted, and cheaply.
Cheers
Ben
