Jabba IHI, Still ongoing

[ibizacupra]

Bill does your current engine have standard internals with 360BHP?

yep... its a worry is'nt it
Another whole days thrashing round a circuit @ Anglesey on 1.5bar boost and its still running.
Cadwell next Friday next, then Kames in Scotland on 26th, then Combe twice in July - assuming its lasts of course..

What happened to the Dahlback manifold, is that on the new engine (with bonnet mods)

No I sent that POS back.. and got my money back.
expensive paperweight that...

Does'nt fit Ibiza like they said it does and does'nt port to largeport size like they say it does either as has been found out by 2 other UK peeps..

not that I like to use the overdone word, but mine is "Custom" and may well turn into another Jabba product if it works well.

......and no bonnet mods with this version

LOL... just the previous "dent" he he he he

I know the dahlback will fit the s3,but not sure if it's worth it ,what sort of gains do they quote?

I know the dahlback will fit the s3,but not sure if it's worth it ,what sort of gains do they quote?

They claim15+bhp gains, but also say when mapped to suit... so perhaps no bolt on gains unless mapped. I asked Hans Dahlback this exact question, and the gains were from mapping and adjusting the boost, so more boost, timing would get you the power anyhows.. I can see it would be better for more evenly distributed cylinder filling via the slot/cone filling but as for more power... Hmmmm

Its a shed load of dosh for next to no gain IMHO...

It cant be reliably ported to suit largeport either, which for me was a requirement. The runners are simply too narrow and insufficient material to port to largeport.

I think Edd Jackson saw gains but sure if these were "bolt on" gains or mapped as well gains. Now he's gone largeport 2.0ltr BIG Sportec turbo he's found out it wont go largeport, so has a step left, which is'nt ideal.

I thought Dahlback were quality but the manifold experience has shown me otherwise in this respect unfortunately. took a dim view of "yes it fits Ibiza, yes it ports to largeport" to get a sale approach when they obviously have never tried.

Oh well, live and learn

Spot the fitment problem LOL

somewhere on my other pc I have internal views of the runners..

 

[ryan_s3]

hmm,i think i'll give it a miss.My next stage will be valves and rods(when cash allows) and up the boost to say 1.5bar.I'm already thinking of the next stage..there must be something wrong with me!Do you think the head will be a major restriction then?

 

[ibizacupra]

get ya car back first m8.. and enjoy exploring the new found power to go with ya grip

 

[ryan_s3]

tis a heavy beast though bill.Although i wouldn't change it.

Ben

what turbo you running? sorry if ive mised that bit,ive put up a new post,about what size of IHI i should run on the ibiza. . i need help! as im goin to buy 1 asap!

 

[Yumann]

The jabba ihi cars run a vf34 ihi turbo.

You'll need a manifold too to fit this turbo aswell as it is different flange to the ko3 on your car.

Also budget a lot more than £3k for the basic stage 3 kit! As you'll need a remap, diff is and essentail etc...

As you can see Ben, Bill has done a fair bit of work to there cars. Its kinda like a evolution process. Can't just do it over night.

But well worth it in the end!

Bloody hell Bill how did you bend that fuel rail to stand up vertically

Did you have the depressurise the fuel system?

My one was horizontal all the way during the fitment. Was very tight to say the least.

That pertrudes quite a fair bit out the ibiza.

Thought my one wasn't going to fit either half way through.

my rail just flopped up there.. its only flexi lines into and out of it on mine. (ibiza thing perhaps)

you got any logs or dyno's yet?

Missed this thread!

Ive got some before runs need to do the after ones properly. Was letting the car get use to the mani first.

157.3g stadard @ 17 degrees
155.9g with mani @ 24 degrees

Think the drop off was dues to the temperature. Would you expect that bill?

That's quite promising with a 7'C temp increase! Wait for a similar day and do again!

Alright Sie you find the pics any help?

You reakon its good i was a wee bit disapointed TBH.

Does anyone know the drop off in MAF relative to temperature?

Was readind some post on vwvortex and some guys that run the Dahlback mani arnt impressed with the returns.

ABD racing have just made a mani, looks nice: http://forums.vwvortex.com/zerothread?id=2089719

This design also looks interesting:
