Hi, here at brazil we have tried to get more that 500 hp: The result:

http://i123.photobucket.com/albums/o295/jakka_album/Imagem067.jpg

The last cylinder blowed up! As u can see.


NOTE: using an GT3076R with some upgrades that I don´t know.
----

So, we went to next stage, we have built an integrated guard block.

Now we are expecting this engine to have more than 550 hp on wheels. I will try to run with 2 bar of pressure.

That looks good, it will certainly be a lot stronger now but i don't understand how the wall blew up. Do you now what caused it; was it a weakness in the casting (which i doubt) or did it just let go?

Good work but i think your trying to run too much boost thats why the first block broke. With the mods you have now done it should hold now. Good Luck

Don't need to run 2 bar boost to get this kind of power - we got 587 with "just" 1.4 bar

George welcome to FCCUK wink

George is preparing a pretty rapid PuntoGT2 with a 16VT coupe engine/box et al. All forged, with some wild cams and large turbo...

Looking forward to a drive before the end of the month laugh

We got 507 hp with "just" 0.8 bar...

We do not did the tests with 1.4 bar. But I think that 587hp is easily reacheble with this pressure.

Hey! O LOVE PUNTO. FIAT is manufacturing PUNTO here now at Brazil. Could you send me some photos of the punto project? davidfdr@gmail.com

But the PUNTO here was launched with a fucking shit engine 1.8 8v 115hp that gets easily broke.

Hi david, pre-colector = intake plenum.
Have you changed the length of the Runners?

It uses the 2.45L engine runners, stock length, but larger diameter

The intake manifold plenum is the turbo version modified with larger air horns
