Thread: Nissan Primera sr20ve-t Dyno

This is exactly what Im getting.. if you switch the cams at low rpm the spool changes dramatic.
thanks.

One dyno is 3rd gear, the other is 4th gear.

What I am trying to say is that the turbo spool is directly affected by the VE of the engine. A higher VE will spool the turbo faster, because it will act like a larger engine. Putting a smaller housing on can lower VE and make it spool slower. I don't think a .80/.82 housing is going to be that restrictive though. It may lose a bit of top end power. This is just speculation though. I wanna see what really happens.

I have seen full spool on a 2.2 with a GT4294r by 4500-5000rpm, which is about where I make full spool. But it makes 700awhp lol.

this thread is awesome. i love it when you guys push the limits on these engines.

congrats on the numbers JP. i know they'll keep going higher and higher

i had a long talk with Clarke from JWT about measuring backpressure in order to see whether cams will help my setup or not. this info is really interesting... it's pretty amazing to see that you made more boost in the intake than backpressure in the turbo mani. time for some big nasty bump sticks!

it;s more the ex. If you switch your intake too low it will hurt spool. This is the reason the ve+t can spool a turbo much quicker, i have been saying this for a long time and now we have results that show this.

with the greddy mss you can switch the intake and exhaust cams separately??
If so Im going to buy it.
Thanks guys.

Yes you can.

If you have plans to run a standalone you should be able to do that easily.

The standalone I am using has 4 aux outputs which I can use to activate what ever I want. I use one for the fuel pump, one for the VVl activation and one for my fans. I have one left over and I am not sure what to use it for. More than likely a fogger

didn't you buy a motec? you should be able to use that to switch cams independently

Congrats on your numbers JP.

Im going to install the motec in a cuple of more months( end of the year)... so for now the mss will work and I can sell it.
Thanks kleensleeper.. Im waiting for your numbers
cheers man.

New info.. I found a pretty big leak on the turbo to fmic side... Remember that the boost was falling a little from 16lbs to 15,5?--now its does not have this probs and the throttle responce its better... this is for now.
