JW automotive have an R32 GTR 26/30 running 8.7s with a 6766. They estimate it's making over 1000hp at the flywheel which is well above what the turbo is rated at.

I'm curious to know what the car will be used for though it sounds like a top endy drag app .
Always with long period cams the dynamic CR drops because the trapping efficiency is poor at low engine speeds , valves open too early and close too late to get much effective compression happening .
Raising the static CR means what air the valves seal in is compressed more so you get higher compression pressure .
Also your call but big cams make for lots of reversion (inlet air going in and partially back out of the inlet valves at lower engine speeds) and having a throttle plate per inlet port helps here .
If I was contemplating a high horsepower RB26 and not using twin turbos or ITBs it may have been worthwhile researching turbo Neo heads with the RB26s valve train . Reasons being you get smaller chambers for less heat absorption area and you can have higher compression ratios without raised piston crowns which screw up breathing to a degree . Also the basic but useful variable inlet cam ability is not a bad thing either . IMO the value in a GTR head is it's valve train and manifolds , beyond that its just another RB TC head that started out in 1989 .
From memory GMS had the CR around 9.6 but that changed when CAMS tried to rein in the GTRs power wise , I think they had less boost with a higher CR to minimise the power loss .
The previous build was 2860-5s and poncams and was hella fun on the street but going for a mainly drag setup this time round with the odd street cruise. Like I said earlier I'm not too keen on wasting the thousands already spent on the current setup. Thanks for the tip though! Maybe do this when I eventually convert my RB30et powered VL to twin cam.
Cheers Simon.

Both me and Paul (piggaz) have already been thru this very recently
Sh&ts just never ending!! lol. Well they are in there now so I will give them a go. If I have to change them so be it and if not BONUS!! Cant believe I havent heard of this before now. I know of 3 cars running tomei top ends with no dramas whatsoever which is why I went that way. What is not going to give me headaches? lol

Has the chamber in your head been modified at all? Head been decked?
Head surface was skimmed

The jap springs are designed for a head with factory height valve seats, once you cut the seats it's moves them up in the head, which moves the valve up and the retainer with it and that lowers the spring tension at rest which is what causes float.
Also put some boost over the top of the valve and the problem becomes even worse
Just like you have said it comes down to if the seat pressures have been checked and are within specs which any decent head machinist would do. Not just slap it together and hope for the best. Do you know of any brands that do shelf items higher than the CP 9.0:1. I cant find anything.

Hope To have a result to post up here in the next month. Built 2.8 stroker with a 6766 1.0 rear on E85. Will be pushing it till the turbo has nothing left.
