They are quite small, I agree. But I want to see that they are capable of. Because if you look at the comp. map they shouldn't be that bad on a 1,5 liter engine. But now when I've build everything to fit the TD05 series it's no problem to switch to a 16G or 20G. :)

Yesterday I was going to cast the plenum in CF but all my epoxy had gone bad so I have to buy some new epoxy.... So I did some other stuff instead. The only things thats missing is epoxy Not so good looking but it didn't take long time to make :) Release bearing to the Tilton OT-2 cluth

more rev => more power Reving a 7M engine to 8500rpm gives you a mean piston speed as high as an F1 car! This is because the long stroke on the 7M. The main bearings design on the M and JZ are alot different to. The M has a larger radius then JZ, this will increese the periphery velocity of the...

Would be nice to beat that! ;)

Ok... so this 814rwhp might not be so accurate?

I've seen Duanes dyno sheet but I found it a little bit odd at the end. Why a break up and then after that the power just goes up even more? The rpm/mph graph might suggest that he popped the clutch or wheel spin or anything... I don't know... Could someone explain this for me...

Ok... But mibrum doesn't drive around the streets with that car...?

Hi I was just wondering what the horsepower record for a 7m-gte engine with out NOS is? Is it 814rwhp?

I just need to get my hands on some sort of vacuum pump. Hope it's going to be some time this week. :) I'll take lots of pics... don't worry :) hehe

Thats one reason. The other is to time the exhaust pulses so the pressure is lower at the valve right when it closes. This way it will suck out more rest gases from the cylinder and you will have a better combustion. This also only works at a narrow rpm band. The 70cm pipes should tune this at...

You can't put a wideband sensor that close to the cylinder head. It will burn up in no time! But I'm going to run 2 EGT sensors on the hottest cylinders and trying to get the stock knock sensors to work with VEMS. VEMS has knock support but it's quite hard to tune. And E85 has very odd...

The forced induction will not even out the differences. If one runner flows better then the other runners will result to that cylinder will have a better volume efficiency then the others. And if I'm close to the knock limit and one cylinder is running a little bit leaner then the other ones...

I don't have access to any flow calculating program so I just used some what the same principle as I did on the runners. Gradually increase the area from a circular shape to an oval shape. It just remains to see if the flow is even in to all cylinders...:icon_razz

Now the mould for the plenum is finished:

Found some old pics when a friend helped me make my flywheel.:icon_bigg

Home made :icon_bigg. And my welding is getting better.

I had to move it back 5 cm to fit the intercooler and 5 cm to the left to fit the water/oil cooler. But it's tight! :icon_bigg

Ok... gonna look in to that later. Thanks for the tip. :icon_bigg

I hwill! :icon_bigg Gonna make some videos when I get it running, then you'll see. If you are going to build a twin setup for good response I would use a pair of smaller turbos. The CT26 starts to make boost at around 2500 rpm on a 3.0 l engine, with 1.5 l to each turbo you have to rev twice...
