parrellel and front mount on BG5

[drakon]

Apologies if this has been covered before.

A couple of months ago I put a Parrellal Extractor setup on my BG5 which was good for high end peformance and having both turbos kick in at same time without VOD.

In the weekend I put a front mount on and have noticed that the turbos dont kick in until around 4500RPM. Is this normal and if so is there anything I can do to make them kick in a little bit earlier?

lol yup remove FMIC?

thats a lot of volume for the wee turbs to pressurise aye

or try to shorten piping a bit/flip manifold?

[drakon]

stink, ive already cut into my bumper I should have test driven it first I guess.

Is there any mechanism or ability to re tune this via Shred or Speedtech using standard ECU?

[drakon]

I am going to do flipped and throw some bigger turbos into it, budget just says piecemeal though

If you have $1500, go single turbo.

Much gains with what you have done thought? (except fmic lag)

What TT turbos are you using?

[drakon]

was running vf13 and vf14 but the primary seized so replaced it with a vf19 was going to upgrade the secondary to a vf18.

when I redo engine at end of year plan is to run either daul vf28's or vf30's but cant do this till I reforge the engine and slap a tuneable comp into it.

pretty sure theyre different flanges...could be a lot of custom work there

[drakon]

yip different flanges but worth the money also hence why I'm doing it at end of year once money frees up.

Dream is to have motor internals all forged flipped manifold to cleanup the front mount issue. and either of those turbos dual on both sides with seperate exhaust running out back (each turbo having separate exhaust piping out the back end

[funkytown]

fwiw those larger turbo's in parallel on an ej20 will be epic amounts of poo's.

the prova legacy based out of auckland and runs a ej257 and parallel vf28's i think and is much more responsive.

[drakon]

Cool thanks for that I will keep that in mind as Im going to buy a new motor anyways to work on before implanting the beast. So a 2.5 might be better to start with.

Searched up that car you mentioned and it seems like a monster which is what I'm aiming for too so nice to know it can be done.

[Divine]

Seriously, single turbo it.

But up to you of course

[drakon]

I know single turboing it would be the easy choice but everyones done that and if i wanted a single turbo I would have just brought a WRX which would have saved me more money and parts would be more easier to get a hold off

[Divine]

Very true. A good parallel setup having no VoD would be a worthwhile venture to document.

More like got N/A with the lag that would have.

Replace EJ20 with EZ30R and you might have a show at response AND power

twin vf or td05, and an ej25 would be fine...

twin gt30 on ez30r or gtfo.
