If you want to come and chop it up be my guest man, I am sorry I just don't have the time. Thanks.

I am sure it would with a few mods, cheers.

Unless you are opening the ports to 90% of the valve head ratio don't bother with bigger than +1.0mm exhaust valves. The bigger valve head can also hurt flow in a small bore. Moreso a problem on intake though.

^^^did someone say "better revability"... oh man!

I am not suggesting anything like that. Without measuring it is wrong to assume, the exhaust manifold in this case may have been a restriction from 4000rpm onwards.

I do not see why you find it so difficult to comprehend. Look at the graph, as it is starting to make power (as boost pressure is increasing) it is making more power than before as a result of less manifold back pressure that allows the engine to breathe better and behave like an N/A engine. Flow through the turbine was impeded by the exahust manifold, simple. It disproves your higher rpm only theory.

Very simple, he has decreased exhaust manifold back pressure.

I would buy them but I am in Adelaide, not sure how that works if they are Vic plates.

Cool plate, bravo levendi... good luck with sale!

I read it! I want to design one and I want you to make it... I am so time poor it is making me sick.

Thanks Bobby email me if you get a chance.

Bobby, early on you mentioned that John looked at making a custom plenum for this engine... can you go into any detail on what was proposed before you scrapped the idea? I have been looking at "Lehmann" style plenums recently and wondering if this is what John was considering.

Look great. Seeing as you have gone to the trouble I would get some external wastegate housings with a V-band exhaust outlet to put on the turbochargers then mod your manifolds for a wastegate... means you could make some simple dump pipes and free up some back pressure.

Really? Well PM me sometime you are around would love to check it out, I live close.

I got a NPC single carbotic button for that, got the flywheel too... no issues. Local support is always good.

Did I see your car outside Plympton Grit Blasting?

With this quench distance, static compression 10:1 what boost pressure will be achievable to make the power you want?

Wow that is a blonde moment if I ever had one, embarrassing... thanks mate

Bobby can you explain how decking the head will not decrease the quench distance? I would be interested to see how much timing and boost can be put in at 10:1 static comp.

Correct!

That is including Ti retainers and spring seat locators. If you need a brand to keep you happy and like burning $$$ go with Tomei.

Hi Craig could you do a custom 3-piece for a R33 GTR in BBS E88 style 18x11.5 +30mm offset Mike

I want to earn what you are! You can put Supertech ones in there considering Supertech make them for Tomei, no JDM tax.

Good on you mate. The probe is the way to go for tyre temps. No need for excessive camber, use your tyre temps as a guide.
