Rb26Dett With Mods Not Making Power :-/

[Deano 1]

Set the cam gears back to 0 on both and do a pull on the dyno 8 and 4 is not ordinary.

I had this probelm with my car, I got diffrent cams but it still came down to the inlet being to advanced if I remember right.

[livewire]

Hmm, providing the compression test goes well it sounds like the cam gears might be the first thing to look at

[Global_Warmer]

See if you can get a compression test today. Shouldn't cost much.

[livewire]

I tried. Booked in for one Tuesday. That was earliest I could get. Fingers crossed its not the problem

[livewire]

Here are the dyno sheets I was given. The reading is slightly higher on the print out because this was The last run done with the exhaust off which only gained 6/7 kw.

[R31Nismoid]

What did the car make with stock turbos? at what boost?

Same dyno?

[livewire]

Never had the car on the dyno before turbos etc were fitted because there are no 4 wheel dynos anywhere near where I live. I Bought everything myself then took the car down to have everything fitted and tuned and had to stay a few days in Sydney while it was being done.

[DVS JEZ]

Where do u live?

Ur comp test will read different with the cam gears the way they are

[livewire]

I'm in Singleton (north of newcastle)

Oh really? So how do I know what compression I should be looking for? Lol. Now that you pay that I'm not so sure I want a local mechanic to do it because if It's not a falcon or commodore they don't seem to know what they're talking about.

[SiR_RB]

might be worth while noting where your cam gears are set at the moment, put them back to 0 for the test, and then put them back to where they were originaly

[livewire]

Ah I see. Hmm :-/ I guess I better mention that to them when I take it round. Or maybe take it somewhere who know a bit more about rb engines

[DVS JEZ]

Singleltons not that far.

[livewire]

Not that far from where? Lol

[GTR260]

My compression test on the 260rs was 170 psi across all cylinders

[DVS JEZ]

Not that far from where? Lol

From me haha. When are u getting comp test done and checking tune?

[livewire]

170 p.s.i at 0 degree cam timing?

[SiR_RB]

singlton to central cost = putty road yiewwwww

[livewire]

Haha putty is fun but a lot quicker to head up the highway and onto freeway.

[GTR260]

170 at 0 degree timing!

[livewire]

thanks for that. I think I'm gonna just wait and take the car to DVS_JET to get him to do the test as he knows more about the rb engines than anyone up this way. We'll see how that comes back and if It's all good I'll see if he can try to figure out what he can on the dyno and testing some other things.
