VR6 TS (turbo supercharged) is it possible?

[VR6-RR 0]

Hi guys quick question sort of.

is it possible to do a turbo supercharged engine?

My only problem is space for pipes if it can be done.

Any suggestions would be appreciated,

Thanks

You would need one very strong engine to cope at least, depends how much boost you would be putting through, deffo wouldnt do it with a normal vr, would need a syncro to start off with imo

Well twin turbo has been done so if you know what your doing then i cant see why it couldnt be done

Well I was thinking of rebuilding the engine and putting in 4wd later when i get clean second car later funds permitting Just wanna get the engine sorted first with low boost

Nah, I want to eliminate turbo lag and just get instant acceleration.

How would you get the charger to cut off when the turbo kicks in? The management would be a feat in itself, and surely it would need a custom built charger? I'd be intrigued to know if this application is possible also.

I know this is going slightly off topis but who did the twin turbo ?

Turbo and supercharger combo is called compound charging.

A company called KMS have done this on several engines, and a bloke has done it on a blue mk4 golf, running a 1.8t 20v turbo and g60 supercharger.

i would use a eaton chager where the ac pump would be and a turbo on tha back, stand alone ecu would be able to do it i would have thought have the charger cut off at a set revs once turbo has started spoling up ..... just my thoughts bit likt the golf TSi i think it is ...

[UnitedMotorsport 55]

Stock ECU can do it!

[bungy 2]

More to the point, who in the club is gonna do it?

Over £600 per wheel for LM's

check E38 mate sets come up on there a fair bit - looking around £700 - £1k depeding on size and condition

Okay, gonna sound a bit daft here maybe. Are we saying that the supercharger is going to bring the boost in first ? I thought they developed their boost higher up the rev range ? At least when I looked into Rotrex that was the case, hence I want to go down the turbo route. Or is the Eaton charger a different kettle of fish ?

[rodney 17]

remember you are in essence splitting your rev range in two... my understanding is they dont both run at higher rpm... but i dont know enough abput them...

[VR6-RR 0]

Well I thought I could use a charger that produces constant power then the turbo would kick in afterwards with the two running together, but judging from the what has been said on here is that the charger would have to cut out before the turbo.

I would like to get them working together but that brings another question of will the block cope with that sort of pressure?

I am going to do it now that I have a company car, just don't how long it will take and I need to get all the info first.

[rodney 17]

well may i suggest chatting to those people on the links above and seeing what they did plus getting a decent drawing of the VW 1.4 lump and then tell us what the **** you do .... LOL

Genuinely interested in this so please keep us posted on your findings...

I was thinking about this the other day, would be very interested in finding out how this goes!

[vr6newcomer 1]

very interested in this also, again i am not terribly knowledgable regarding this matter, but seeing as a supercharger supercools the air on the intake, and a turbo works off of used exhaust gasses, subject to getting the correct mapping i dont see why it wouldnt be possible, with something like an extra 100 bhp from both of the f.i devices?
