Saw this on the US site, thought some of you guys would appreciate it, 284hp out of a vg30de.

I'm liking that. Just needs 2 turbos on it now :wack:

NO it doesnt:tt2:

I wanna know if they are American horse powers or UK hps.

I also want to know how he has achieved it:yes:

It's all about the high-comp turbo setup :D

Love it.... Not a bad looking zed either. Would like to know more about the spec...

Knife edged headache method you mean? lol. What do you recon would be the max boost you can put through an NA block without dangerous heat levels causing damage. I read that the NA has weaker wrist pins rated at a max of about 350hp.

I don't think many people have to worry about hitting 350HP with an n/a :cool3:

Sorry just re-read that :oops:

Stephen is talking about how much if you boost a NA block.

The car does have an impressive spec list. It was owned by Shawn Holleman who used to work at Z1. All that work though....and still less power than a stock TTZ. :p

Here's an engine-bay shot....

Cheers for the extra info Si, as you say all that time effort and money to get less than a stock TT... I'm sure it's responsive and fun but hell. From a techno geek point it's very cool but considering what you could have if you had pumped that time and money into a VG30DETT instead is sickening, I bet that money could produce a 500hp TT

horses and courses comes to mind.

I bet the list of changes to this is huge. did anyone have luck finding a spec list

I doubt that, I suspect it's more like 350hp per pin/piston

Do you think it could go more?

Would all the engine parts be exactly the same then N/A or Turbo.

No.

Parts are different, but yes you can get a lot out of the NA block (with some turbos!). You just have to tune according to the higher compression and have good fuel

I couldn't tell you unfortunately, there are various reports on other forums where people have built high compression turbo builds using stock NA bottom ends with an appropriate tune of corse. Most seem to agree 7-9psi is about all it can take with the mapping performed. Some chap made 340RWHP on 14psi and the wrist pins failed first, accordingly TT and NA wrist pins differ in the material composition and are a weak point, where they damaged previously and the weakest component failed first, I think that's a valid question. Apprantly wrist pins are more prone to RPM damage than load. Dunno I have no first hand experience of it, as I say it's just what I've read written by people more experienced and knowledgeable than myself that I've stumbled across during my research surrounding my own issue. I can tell you that the stock map and stock na with stock boost doesn't last long, that is from experience sadly.

On first glance it all looks very similar but there's lots of important differences. The heads, it's debatable about the actual head casting as to wether they are different, the TT has inconnel exhaust valves to handle the heat of a forced induction engine. The pistons are different in there construction, not only are they a different shape to change compression ratios, the TT ones contain an oil gallery to help cool things down. Con rods are the same but the wrist pins are different. The oil pump and filter tree are different, to help with the added anncileries(turbos and oil cooler) there are other differences aswel which are convertable, oil take offs for turbo feeds and returns. I think that's about all of it.

ok, that makes more sense.

That looked mighty quick! Did I read that it's on E85? So more boost is possible without det risk. Ohhhhh I want my car sorted already :(

Trying not to steer away from the forum topic to much what is happening to your car Stephen.

I won't litter the forum over it, you will be able to work it out if you look through my recent posts, not just that the people concerned are being given a fair chance to rectify things which hopefully they will. Essentially though it's broken.

Yes e85 is like race fuel, very det resistant and runs cool, but you need a lot of fuel delivery capacity as you need approx 30% more volume compared to normal petrol
