ATP GEN II fitted on Seat Leon

[Ditbayki]

A couple of months ago I had the ATP GEN II kit from www.vwturbo.com installed on my car.

I was wondering if anyone else has this modification, so we can share experiences.

To run this kit i have got modified K04-software, 1.4bar spike to 1.1bar at the redline.

Power should be around 230whp :D

As far as I know I am the only one in Holland, but for sure there must be others!

Anyone?

Greetz,

Went dynoing a few weeks ago to get some figures of my Garrett equipped Leon.

Power is measured at the wheels

Run 001 & 002 in 3rd gear
Run 003 & 004 in 4th gear
Run 005 in limpmode (6 PSI)

Dynorun 003 translates to this figures:

I was told the maximum power delivery at 5200 was due to the flowing limitations of the manifold and maybe the injectors.

Like to compare this with Jabbasport IHI Stage I results!

And now I know why my clutch is slipping sometimes when slamming the throttle ;)

Jabbasport Stage II kit results above on lowest boost and max boost at that time.

Yeah, on paper this looks funny. It's the most known dyno of a IHI-conversion. Not quite compareable, few remarks.

The difference is I am using stock internals, stock intercooler, stock manifold and stock fueling.

And I thought on your Ibiza these are already modified, besides a larger IHI VF-22 instead of the VF-23 used in the Jabbasportkit.

The conversion cost me about £ 2500,- installed.

It's a simple bolt-up with chip 'n stuff, just like the IHI stage I-kit.

I am eager to see the difference between a Garrett GT28RS (ATP) turbocharger and a IHI turbocharger (Jabba) on the stock manifold (will it flow?) Stage II vs Stage I.

I could go costum tuned too (GT30/37R slamming 350whp) but's all about the money...

Are there more results?

This is the first generation IHI.. the small turbo not larger one to correct you. Stock internals. Stock IC. This is as low as it gets :D

Note the boost you are running to get your power vs the boost the IHI runs... 9psi is 250bhp. 15psi is 325bhp on a std motor on mine. (was several months ago now however and my spec has changed since then)

Injectors are uprated as they have to be for sufficient fueling. Are you saying you are using stock injectors? 4bar FPR at least req'd... but be careful.

IHI also is a bolt on.

Not sure what point you are trying to make dude. :)

Exhaust manifold on Jabba will flow 400-500bhp with a larger enough turbo running big boost

Lets hope the ATP manifold won't crack and distort after many heat cycles like some ATP ones do. :rolleyes:

Stage 1 Jabba is supposed to be ~280bhp, but I think this is something they will struggle to hold down that low. 12psi was 286bhp on mine. Injectors are a must have for anything over 240bhp IMHO on Ibiza. Don't rely on your fuel pump to deliver a reliable 4bar if considering that.

Nice to see another kit. LHD car based tho not to forget.

Yes, I am running stock injectors at prox. 4,2bar.

BTW are the Leon (180ps) injectors larger then the (156ps) Ibiza?

I thought somewhere in recent posts you had different pistons and a CR of 8,5:1. But you did these mods later. I see you pull with decent torque to 7500rpm, was this with the stock MAF? Because I suspect the MAF of limiting my current set-up.

The thing is I am running a Garrett turbo fitted to the standard Seat exhaust-manifold with a small adaptor plate which has a garrett to kkk bolt-pattern.

The Jabba stage I uses a adaptorplate too together with stock injectors.

So the thing is to see if it spools up faster and how the power delivery is at high revs. Will the Stage I kit max out at 5300rpm or 6500rpm?

I think the Leon 180 injectors are higher rated. Be aware that the fuel pump may well sag under full duty >4bar FPR.
The CR mods were done later yes. now run 21psi boost.

The Jabba IHI on an adaptor does flow more... This will not be the restriction for your rpm... especially if you go to the trouble of porting the manifold out.

MAF is modified in an S3 tube. You will need more.

I don't know of a Stage 1 car around, nor any other IHI dyno's other than my own, which is somewhat out of date.

Rev limiter is moved up to 7500rpm on Jabba.
