Thanks Dave,

We were extremely happy to get 1000hp on E85, not sure if that had been done before, but to push it further now we are switching to c16 and more boost. The engine had perfect compression after the power cruise event, so we are happy to step up the power and see how it goes. Obviously the GT4788R is a big turbo, so there should be plenty of room to move from its current power figure. Fingers crossed it performs well at Autosalon. If it does, we will make the trek to Autosalon Sydney with a few more goodies added to it to go even further.

Actually my friend who owns the Rockstar GTR made 1000hp atw on E85 just before Jambo, and that was straight out of the pump :happy:

It is running a big set up stroker and all the other good bits you know people wont give out there specs on the engine.

Until you ring the person who built the engine. Fact is, there is no use keeping that stuff a secret. It's all been done before. Only the tune is different. People have been making over 1k for many years, it's just a matter or how many more are coming up

True that - Most people will freely give you thier parts list.

However its all the stuff in assembly and small things that make the difference. And you rarely find those on a spec sheet :P

What is the rev limit on this? Given it doesnt fall off boost between gear changes would suggest at least 10,000? :(

Yeah those Nitto cranks are good for 12k apparently. Well so Nitto tell me

Guys, we just took out runner-up for Highest Overall Horsepower at Gold Coast Auto Salon with NITTO putting out 1071awhp with no nitrous!!!

Currently, we're running an Autronic SM4 ECU + CDI but we're upgrading that side of things at the moment and it's 'only' revving to 9500rpm. There is much more to come out of this car and we're looking forward to the Final Battle in Sydney in a couple of months.

The Rockstar GTR put out 950awhp (not over 1000) on E85 too, we were talking to him at Jambo (nice guy!)

It made 985awhp and that was with a slipping clutch so no dout that it will make over 1000awhp with the new clutch. It runs pump E85 and no NOS and it is going to put more boost into it soon.

Well that's strange because he told us "950" but much of a muchness - but he hasn't made quad figures on E85 yet, like we have. Yes, we do know all about that car we were talking to him for quite a while at Jambo :cool:

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.

      Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
