I cant decide what turbo to go for with a 2.1 cdb build with avcs heads and cams.


aiming to break the 500bhp maker on v power with good early spoo as I hate a laggy turbol and response


id even consider going twinscroll car will be used for a fast road/ track car.


what are you opinions?

 

Rotated or standard position?.SJ.

 

I would say standard position as going rotated seems a lot of work for the gains im looking for.

 

I've been looking at something very similar and to break 500bhp on vpower with a nice spooly turbo is tough going! It u want to go twisted a billet 30 with 0.63 housing would the best of both worlds 500+bhp and great spool, add a splash of meth and u could be 550-600 :-). If u wanted to keep standard Postion a s206 or MD321v will see u knocking on the door of 500 and if ur lucky may break that Magic 500 on vpower.

At what rpm would full boost be in though? and how would they compare to the twin scroll versions?

 

MD321V (Lateral Performance)
MD555 (Turbo Dynamics)
SC54 (Scooby Clinic)
or if you have the extra money to go rotated a GT30 would go like stink.SJ.

 

You're looking at around 4kish rpm full boost

 

This is mine 2.1 with s206 and 272 Jun cams and meth

 

You got Boost graph?

 

One i forgot I was a passenger in a car with a Turbo Technics S206 fitted to it,his car went very well.I think he said he purchased it from enginetuner if my memory serves me right but that was around 5 years ago now.SJ.

 

I've got an S206 and a 2.1 from engine tuner to be mapped on the 8th january, I'll let you know how I get on. Meth will be added

 

on my old classic with a 2.1 and s206, I had 450 bhp 400 lbft, then had the billet wheel fitted, but sold the car. From what I read, it then went on to be over 500

 

My 2.1 s206 on standard cams and ODB, was pulling 517hp on v power and 550+(? Never tested) on the meth map. Before the billet upgrade I did 485hp on v power and 535 on meth.

New engine with all the trimmings will hopefully see me close to 600 on an s206. I don't know what full boost rpm will. Be, but significantlylower than the previous engine I am sure

 

Owen developments do some great turbos, worth speaking to them about what you want but wont be cheap..

 

Yep, but then again a v2 build with avcs won't be cheap either!even a 2.1 withall the trimmings like that is still ITRO 10k!

Have you ever been in or. Driven a 500hp car op?

 

Stop trying to make him scared J.Anything over 450bhp can be a handful though so just take your time when its built if its your first time at those power levels.SJ.

 

I've got over 400bhp and that's plenty for a road car and that can scare me at times.

I wouldn't want 500+ for a road car maybe if I was using it more on track I might?

But then again if I went in a 500+ I may change my mind

 

Can be a handful? Definitely will be a handful.... Not sur eon the current spec of your car townsend, but do you have a 6spd, brakes, coilovers etc?

You are more the welcome to come have a look round mine any time you like and have a chat about it,

 

No one strictly NEEDS 500hp, however, it is fun , 500 is too much in a classic to use on road 100%. Mine regularly wants to kill me....

 

My graph

 

.SJ.

 

Remember J a driver controls the machine that he's using and not the other way aroundSkill and experience is the key qualities of a good driver.SJ.

 

Lol i agree. 500 is a lot for the road. The speed u catch things is unreal you've got to be focused 100% at all times when foot to floor. My legs start shaking after i do a few runs but it's soo much fun weeeeeee

 

Oh I am well aware of that, but no matter how good you are, when you push things, it bites back, that is the joys of a classic...

Yep, if you use your full 500hp, things happen at an alarming rate, you need to be fully aware and on the ball at all times. Scariest moment I had was over taking 3 cars, coming up over a hill and the car probably a 1/4mile away did an emergency stop, I caught him at an alarming rate of knots and with cold brakes made it interesting on how to stop the thing!

 

Ive been in a classic with a forged 2.5 and S206 turbo and I cant imagine anything quicker, the way the car accelerated was unreal, but I guess once you get used to it its never enough, and you want more and more!!

Personally I find 350bhp in a classic more the enough for the road!!

 

my car is about 300bhp but ive been collecting parts, ive got coilobers 6speed non dccd conversion cdb, il be doing this build over 2016, im not in any rush to do it as the car is not my daily but I don't want to do it half arsed and look back and think I should have done this and that. fastest car ive been in is my mates 500bhp b5 s4 which I thought was amazing!

 

cheers for your help mate and everyones, looking forward to seeing what yours produces once you've run it in

 

I read somewhere that they are meant to be quite laggy? ive not got any personal experience with them though but ive seen them on an evo build im following and the turbo does look the part

 

I wouldn't bother if you want a standard position turbo pal Owen developments will not sell you a turbo directly

 

Still going strong �� Running 1.7 bar, I'm sure Martyn would have a boost graph some where
