Building An Rb26 For Response....

[Piggaz]

Response won't be sacrificed at all. Depending on how your boost control setup, it might even improve.

I recently got my car tuned with 'response' in mind.

I have -7's, ID2000's on pump 98 and stock internals, and this was the result:

Does this graph represent a "responsive" engine? Certainly feels responsive, as in there is very little lag when going full tilt.

Obviously it has a long way to go as far as HP is concerned, but would that response be sacrificed if boost pressure was increased?

It all depends on the tuner. I get full boost by around 3900RPM for my 320KW. Though i dont have stock internals. Is there a reason you got ID2000? Large injectors for the turbos you are running. Also what AFM are you running? that to me looks like stock AFM maxing out.

Running ID2000's because I will eventually run e85, just ran out of funds to flexfuel setup. Everything else is ready to go though, twin 044's and surge tank etc.

As for AFM's, I switched from a vipec to a haltech platinum pro, so it shouldn't be relying on AFM's as far as I know.

Interesting. Could possibly just be the age of the motor.

What would you be expecting? We did ask for a reliable tune. When I decide to rebuild I will chasing HP but at this stage I want it to last as long as possible.

270 @ 16-17psi is fine

Wouldn't know without looking at the actual health of the engine. Your tuner would know what they are doing. Best to keep it as safe as possible. My tune isn't overly "Safe" its a bit agressive but i have had a ground up rebuild.

That is a nice curve though. From what i've seen most cars run around the 270-290 mark that are still stock internals.

Honestly until you even think about doing internals i wouldn't put in on E85. Has the motor been rebuilt previously? if not 20 years is a long time worth of thrashing haha.

I should have taken some photos of what my motor did to itself...

Edit: as zebra said. It's fine. Im pushing 21PSI through mine...

Thanks guys. What is the ultimate response setup on an RB26?

[Anfanee]

the sky is the limit. I lie $$$$$ is the limit.

Legit though how much do you want to spend?

[Duncan]

standard for sure.

nothing spools up like a little ceramic turbo

no idea, just want an idea what options are available.

[Wongy]

This was my last tune:

Hoping for abit more torque low end after my next parts and tune.

[Piggaz]

I can see why. What on earth is going on there?

like this

though the rpms aren't right, you get the idea

What actuators are you running?

[XKLABA]

Factory, its all stock in that run with a HKS EVC 4 controlling boost

[gtr jet]

Shit that's good for standard actuators. I can't believe they still hold boost that well.

Haha,don't know,hoping to fix it with next tune,that tune just then was a lazy tune I think,took him an hour

it's more the way the cams are set, making better use of the air it gets meaning the turbos don't have to working as had

a good quality boost controller doesn't hurt either

what mods have you got done ?, cause yeah that's not great at all, what boost is that ?

cam gears ? if not get some
