THat is sick. Looks good. Try to keep that page saved on the process.

nice fabrication and all but not good for a whole lot of hp. i think he said he used 2 t25's or t28's, something small.

Yeh i was thinking the same...pretty small turbos on there...but there are 2 so the benefit should be alot less Lag than a single one with the same output of 2 i gather..Yes No? Maybe the experts can fill us in on that.

Probably no more power than what we can put out. Don't forget Sweeney's twin turbo results vs Todd's - not too different except Sweeney's was more of a PITA

Consider the vehicle he put the engine in -- going with a single turbo might have been more cumbersome.

Yes, two turbos, but you also have half as many cylinders driving each one. The only reasons to go to twin turbos is for packaging, the "twin turbo" WOW! factor or if they're sequential.
I used the twin turbo setup so that Todd could have a turbo on his car as the twins required a lot of fabrication that Todd didn't have the tools for to get them to fit the chassis. We swapped my single setup for the his twins. The trading of the turbo kits spawned the creation of TurboChargingDynamics as it is now and the sun shined brighter, the birds sang and the old BMWs ran with the modern super cars.

And I'll never be able to thank you enough!

Bastards!

Awwww they just had a little moment

CUTE! :p

But yeah - lets all just keep to one turbo... they were just making it too difficult.

and in an e30 wow. How come people dont route the intake tube like that normally? I always see it come from the passenger side across the engine with the turbo setups?

is there no advantage at all to a parallel twin setup? I understand that you're using less exhaust to push a smaller turbo. Are exhaust volume and compressor size the two big factors in turbo lag ? If so, i assume the ratio is non-linear, (i.e. lag is a function of exh volume / compressor "bigness", but at one end of this ratio there are advantages/disadvantages)

I'm wild-eyed toying with the idea of a bi-turbo V8 for my Audi (after the MS2 install is done That application seems naturally suited for a twin setup. The plumbing for single turbo on a V motor seems dumb...
