Thread: Think I went with too big of a turbo...

I'll send him an email . Is he in the country (USA), or is he overseas too?

I'm not looking for much top end, just like SE-Rican, I like a massive and torque powerband for my daily commutes. Makes it's more fun to drive around town without speeding .

Even if I go with a tubular manifold, I plan on keeping the VET cams due to low overlap.

On another note, how many of you guys tried using the E60 maf? Calum told me to use it over the N60 a while ago. I remember that when I switched from my DE maf to E60 maf, butt dyno felt like I lost power. I then went to the dyno and made 230whp on 9psi on a BB T25. My VQ table was a bit wrong in the higher voltages (4.8v+).

I'm now wondering if the E60 maf's that I have tried to use are just faulty (I have two and both read around 1.05v at idle). That's a bit low as per FSM. I did clean the suckers out with MAF cleaner after, and still the same voltage. I have a Z32 maf that I have been sitting on, maybe it will be worthwhile to get it hooked up and see if it reads better. Reason I have been avoiding it is because of the low end resolution on the Z32 maf is a bit lacking.

He was in south america last Time I spoke with him.

here is a reasonable high power dyno running vet cams



PS go the z32.

I wonder what makes them so peaky/torque at such a low RPM.

I might hold off on the Z32 because I'm sitting on an OBD2 plug AEM Standalone. I just don't know if I want to make another step down harness...

low durration big lift constant ex lobe small duration but big lift duel intake lobes.
The turbo on that set up posted is quite big. Hence why it shoots up soo quick

Ah that makes sense on why they were able to get the overlap down too then. Makes me wonder what the gas mileage is like on it.

with the vet cams you will notice quite a gain in spoolup time. If you go back and read through jp's posts. You will see that on as big of a turbo as he was running he noticed a significant increase in spool time with them. Your turbo will make more torque down low and spool quicker than jp's but yet still hold out power. I think its everything you are looking for. And im sure once you get them in that you will notice you will be able to add more timing in as well because you wont have the reversion issue.

that powerband is huge. You can see that he could benefit from a larger cam at that point. But still, the torque is crazy.

you def dont need a standalone but hey its not my money

I would say get a good tuner and see what he can do but i know you tune your own cars

coheed, something that i forgot to mention...what size is your collector, also how long is it and what is the angle the runners merge into each other. these variables will affect spool as well as your top end, longer collector and also larger diameter will give you more top end, also this can be abtained just by running a larger ID runner with a short collector

Before I ported the divider to gasket match it.
