ehehehehhe

just got back my lovely car from dbilas...

sorry for the video, I'll post a better one as soon as i have the time to record it

in the autobahn I met a 360 challenge stradale, until 220km/h i was a bit faster.

oviously after that he said goodbye to me!

0-160 km/h = 9,5 sec

Not much to see on the video, as it's almost pitch dark But it sounds good Keep it in one piece

Cool I tried really hard to get some information on this conversion from Regal (the UK distributer) but only got a photograph of the air intake (after a number of phone calls and emails ) Do you have any photographs, or a dyno graph print out Sounds lovely

[Particle]

Perhaps i can provide you with some information about the Dbilas Turbo conversion kit.
In the Opel-Speedster-Club forum (german language) we have organised a group buy of the Turbokits.
Last but not least, 19 people from Germany, Austria and Italy decided to buy the kit.
You can find some dyno printouts in the according thread on page 29,32 and 33 OSC-DbilasTurbo-Thread

Last season 2 of my friends had the kit fitted to their VX already.
One friend has "tested" the kit on the Nuerburgring Nordschleife (northloop) the whole season -- without any problems.
With the other friend i toured through the alps (e.g. Stilfser Joch/Stelvio Pass) -- no problems as well but lots of fun by overtaking all motorcycles
For me, those "tests" were evidence enough to decide to buy the kit. So far, all of the group buyers were very satisfied with the price/performance ration of the kit. Dbilas is also an ISO certified company and member of the VDAT, the organisation of reputable german automotive tuning companies -> www.vdat.de -> "Mitgliederliste"

Price for all parts incl. fitting, legalization by german TUEV, calibration on dyno & graph
incl. Blow Off Valve and a 2 year engine warranty -> ~ Euro 5.000

Dbilas offers also an additional oil cooler kit and a special ss exhaust designed for the turbokit with 63mm diameter.

Any further questions?
I hope you don't mind my very basic english language skills....

Regards, Gregor

Edit:
I've just seen that there's another Dbilas Turbo Thread here incl. a dyno graph.
It's Ste's car from Italy. He and I organised the group buy via the german forum.
@MaxX LA 2172 -- Hello Massimo, i hope you enjoy your "VX220" Have fun!

5000 euros is "good" value then..... as im sure the UK sellers would charge £5000+ ....... and the supercharger people too.

@MaxX LA 2172 -- Hello Massimo, i hope you enjoy your "VX220" Have fun!

looking at the other thread then the top power quoted there is Normal power at 183.kW which is 246 bhp

If I'm reading it right the wheel Power is 183 bhp which seems a bit low, but i can't find a graph to compare as courtenays site is playing up.

[vocky]

183 whp my 2.2 normally aspirated was 179 whp with a 2" exhaust

Edited by vocky, 17 March 2008 - 03:20 PM.

Wheel power + Drag power = Engine power or in the diagram: P_Rad + P_Schlepp = P_Mot 185,5hp + 61,4hp = 246,9hp The dyno graphs from Dbilas vary between 246 and 263hp, depending on the rpm reached and the gear selected (4th/5th). Please take a look at the diagrams in the other forum...see link above. Dbilas guarantees the power output of 260hp ("Leistungsgarantie" ). However, there is a strong variance of the series power of the 2.2 NA engine.

[vocky]

a standard vx220 has about 115 whp, so the equation 115 + 15 / 0.9 = 145 bhp or 30 bhp transmission loss mine has 179 whp, 179 + 15 / 0.9 = 215 bhp 183 whp, 183 + 15 / 0.9 = 220 bhp 60 bhp just seems a massive transmission loss

[Particle]

@vocky congratulations -- you seem to have a VX with very low drivetrain losses. In the german forum, the range of measured losses (for the 2.2l and the 2.0l VX) is between 21,7kw (~29hp) and 45,5kw (~61hp) There is a huge number of influence factors for the loss measurement and the losses increase with higher rpm...trust me, i could write a book on that topic ( "The high losses must be on the transmission side/caused by the transmission" ) BTW -- you've done a nice job with the M32 tranny -- too bad for the good old 287 unit

[alanoo]

Don't forget vocky as no more balance shafts (and has no A048's too), so it is absolutely possible that he has transmissions loss on the very low side

[mandarinvx]

and a whole load of other mods, still NA tho Any more information would be great, as I said earlier I couldn't get any from the UK distributor Sounds like a good price for the kit, but what does it include, everything to do the job, or just most parts Is a remap of the ECU required, and if so how is this done, by post? Do you know the outlet inner diameter of the exhaust manifold, and can a standard exhaust from the manifol back be used, or is the flange position changed? Do you have any pictures of the install (or links to threads) Sorry about all the questions!

[slindborg]

the balancer shafts wouldnt alter the driveline losses. also its worth noting that the losses arent a "constant" ie its not like you dont move till youve put 16 bhp into the gearbox to get 1bhp at the wheels etc. its more a constant rate and the losses are tricky to estimate as its all down to how shifty the RR operator feels like being.

[vocky]

I only go by the whp figures, the fly bhp is always a guesstimate it's just strange how transmission losses vary so much mine had the F23 and standard wheels/tyres with the 36 bhp tranny loss. I'm sure the turbo'd z22se is a superb engine, especially in a vx220/speedster

[Particle]

Sounds like a good price for the kit, but what does it include, everything to do the job, or just most parts
Is a remap of the ECU required, and if so how is this done, by post?

The kit for ~5k Euros included:
- Dbilas Turbocharger
- Flowtec intake manifold and exhaust manifold
- intercooler
- FlowMaster air filter system with FlowPipe
- sport catalytic converter 200cells
- intercooler pipes with hoses, oil- and coolantlines
- Blow off valve
- Remap of the ECU with Dbilas engine map
- installation/fitting of all parts
- calibration on dyno
- legalisation by German Tuev (German safety standards institute / car examination)

All in all, it took Dbilas one week (@Dbilas Dynamic in Roedermark near Frankfurt) to complete the job. You don't need to do anything just bring the car on a saturday to Dbilas and fetch your new "beast" a week later

Do you know the outlet inner diameter of the exhaust manifold, and can a standard exhaust from the manifol back be used, or is the flange position changed?

I am pretty sure the inner diameter of the exhaust manifold is 63mm. Connected to the exhaust manifold is the catalytic converter and then the exhaust. Dbilas usually recommends at minimum a Bastuck exhaust. Fitting of any other exhaust (apart from the standard) should be possible -- in some cases additional rework of the exhaust maybe required.

Here a sample picture of the installation (thx @Speedy2408) -- you won't see much. It all fits inside the standard rear clam. No changes to the rear clam necessary.

[mandarinvx]

Thanks mate, just what I wanted to know One more (sorry, again ) does the turbo fit straight onto the exhaust manifold, or is it poitioned to the side of the engine? It just doesn't seem like there is enough space to fit the turbo in (at least not without melting/burning a custom hole is the clam) Do you know if they removed the clam to fit the kit?

[Particle]

Yes, the turbo fits directly onto the exhaust manifold. As far as i know, they remove the clam to fit all parts properly. There's enough space for the turbo - no changes to the clam necessary What i've forgotten is to say that they increase the rev limiter to 7200 rpm. From 2000 rpm onwards, you have more acceleration than before and from 3000 to 7000 it's a hell if you are used to the 2.2 NA before. :ph34r:

[mandarinvx]

Thanks again

Shame the Euro is so strong against the GBP (for us!) as it comes out at just under £4000 at todays rate


Have they changed the valve springs to raise the limit to 7200rpm?

I say that as the GM performance build book states that the springs are only good for 7000rpm before they need to be upgraded



Taken from here - you'll need a broadband connection tho

Obviously that isn't saying they will fail, just a recommended amount, but they have carried out very extensive testing on the Z22

[Particle]

No, they don't change the valve springs. The engine will not be opened at all. Only thing they replace are the injector nozzles. The rev limiter of my EDS software before was also set to 7200 rpm. In my opinion, you'll stay 99% of the time below 7000 rpm anyhow.
