RS2 spec live map limiting factor?

[Tonks4x4]

Hank has had a few vehicles do between 400 to 420 on pump gas.

Yes running RS2 injectors maxed to 99.8 duty cycle.
I have a set of 1000cc EV injectors to fit and water meth to be used only as a safety.
Will be getting round to getting it sorted and mapped in the new year.

What's your power target for the RS2 billet with the 1000cc injectors?

Ok, you have me convinced, I will go billet k26!

It is not good to run over 80% duty cycle on injectors. Get 550 cc @ 3 bar to be on safe side. You can boost the press to 4 bar if you would need more. Use Bosh 040 fuel pump form old Audi k jetronic to pump the fuel.

I'm runing my K26 on the race track ... it is responsive look at the videos https://www.youtube.com/channel/UClx...gynbMJGPOVvT4w

I can make a bet that it is more responsive than the RS2 turbo. This is why I did not get it my self. It has much older compressor wheel in technology aspect.

Apparently the injectors max first;

Out of interest, what is an RS2 turbo actually capable of bhp/nm wise? Always thought that realisticly an RS2 turbo could make maybe 360bhp/around 500nm?

About 375/590, but not on stock (RS2) injectors.

RS2 injectors are not even big enough for a standard RS2 turbo, never mind a hybrid.
They are 360cc and the max they can do is 1.8 taper 1.35 on boost.
A standard RS2 turbo can run 1.8 taper 1.45 and a hybrid can run 1.8 taper 1.6..

RS2 hotside does not flow 400hp without either massively lowered CR or chemical octane boosting/charge air cooling

So it would be worth fitting 440s for a live map.

Live map was also to optimise everything to this setup, should be able to get a bit more than a generic chip.

Buying Albert's turbo and selling the RS2 would not cost any money if getting a live map and would apparently get 450bhp+

It reminds me of the time I texted a friend, asking about a VW Caddy Maxi, only my phone changed the word maxi, so it had a n and a z instead of the m and x.

Oops.

God bless the iPhone spellchecker eh??

[Tonks4x4]

Yes Sal, it did 347hp on the dyno and that was as far as we could take it with the injectors running at nearly 100%.

I think you may want to edit that

Mine's 360 and a bit on RS2 injectors...

Sure on an ABY 4 Bar FPR, you'll be OK for what an RS2 turbo can blow.

I'd say get a hybrid with bigger injectors and go for 400, like Dobbin did @ MRC last month.

[sal_s2]

did I read that right? rs2 injectors maxed out at 340bhp?

[Tonks4x4]

Yes Andy exactly that.
