Rb 2860-5 Highest Hp?

[Jc052685]

This was a year ago on 13psi and pump gas (and i guess it was 480whp)

[Hadouken]

1000cc injectors is way to small for 500kw on e85.....

Or at least a Aussie 500kw that is.

[Jc052685]

So what will 97% dudy cycle on ID1000s on e85 get you guys? Though it was actually E70

[Hadouken]

400 ish kw

[Jc052685]

Interesting...

I asked in the other thread but..... do you guys trust Mainline dyno numbers?

[GTR_JOEY]

400 ish kw

Even that's pushing it

[mr skidz]

yep

So you're restriction remains present.

[Jc052685]

The restriction being what? The inducer its self? Restriction would be anything befor or after the turbo that would hinder flow.

[XKLABA]

Lifting base pressure 15oddpsi will see more flow for more topend

What C/R is it running

I was being nice

You talking about raising the fuel pressure? Its already at 58psi. Figure another 25psi when under full boost you are looking at 83psi rail pressure.

Not sure on cr

Yes the inducer and compressor cover inlet.

[mr skidz]

You're making more power at your engine flywheel then the turbo can flow on a test bench on its own with no restriction in front of or behind it, see what I mean?

This ^

I made 604hp with my -5s on my Tomei motor at 27psi (still 2.6) on E85 with 1,000cc injectors twin bosch pumps and a Walbro 460 lift pump (to surge tank) and they were almost maxed out

Most GTR-s that run -5s here in Oz make between 450-480kw max on corn syrup

I think dyno read out is a bit too optimistic IMO but we all know how to settle this don't we?

you will need a drag strip

and a go pro

and a pic of 400m..........wait..........I mean quarter mile timeslip

The old US dyno chestnut. Been having this arguement on the zed forums for years.

No, I mean 58psi base is already 15odd psi higher then the base we usually see, mine is at 50psi which is already high then normal

You don't know what the compression ratio is ?

[mr skidz]

What is the smallest id of your exhaust system?

[Jc052685]

3" I believe.... And its Rickys car, just so there is no confusion.

I did not build the motor so I do not know the specifics.

most modern fuel systems run 58 or so psi. That is where we normally run things. Had this car at 43.5psi in order to help with pump gas drivability but we had to turn it up. The ID1000's are rated at about 1150cc/min at 58psi.

[mr skidz]

3" That won't be anywhere near enough to get you 700 wheel

Odd..... I have made over 900whp on a 3" exhaust. Even that much must cover our apparent over zealous dynos.
