nice set up man...who fabbed your manifold for your turbo?

I thought the Borla stayed to 3" all the way as well..

Nice numbers btw man. I find it pretty amazing on what the '8 can do when pressurized. When I'm talking to haters on the '8, I just tell them that it makes more power than the '7 when pressurized to less PSI. Pretty pimp if you ask me.

jajaja malas intenciones!!! cuidado con la mezcla y sobre todo el tiempo lleva la mezcla a 10.9 y el tiempo total a 10 grados con gasolina premium y pendiente a las detonaciones si detona baja el tiempo total.

Saludos y Exitos!!! en tu proyecto

If those numbers are correct, 304 WHP with 7.5 PSIg* seems pretty good. NA is 14.7 PSIa; adding another 7.5 PSIg is equivalent to 22.2 PSIa.

Roughly speaking you have 50% more air and 50% more power than stock; sounds like everything is working fine including your exhaust.

*PSIg = PSI-gauge. PSIa = PSI-absolute. PSI-absolute = PSI-guage + 14.7. Meaning your absolute pressure is your guage measurement + standard pressure.

I had a local shop do the work. I believe he made a jig so that he would be able to replicate it for future costumers.

I'm thinking I just may have a bad wastegate. We will see tomorrow.

I will most likely sell my exhaust and go with a 3.5" straight thru single tip design.

Does anyone know where I can start shopping for real nice 3.5" Mufflers with titanium tips?

I could pressurize a blimp to 7.5 PSIg and inject that air into the combustion chamber. Is that 50% more air? Hell no, not by volume.

mass of air pressurized to 7.5PSIg contained within large turbo > mass of air pressurized to 7.5PSIg containted within small turbo

Hi, what gear did you made the pull? Because in less than 90mph is look like you did the pull on 3rd and not in 4th gear, isn't right?? Just want to confirm the gear you made the pull.

Thanks,

Antonio.

Very nice, I like the placement of the turbo better there than in the front like some of the other set-ups out there...

edit: and a question, is this a Turbonetics T4 60-1?

ok, im a mechanical moron, wish i knew more cuz i love the knowledge u guys have of the subject. BUT, in lamen terms...what turbo are you using? i know a lot of it is custom but help some of us mechanical morons out with some tips to embarass some 350z's

MrWigggles

Wow, I even said "roughly speaking" and get this type of reply.

Yes, 7.5psig is probably going to be a little less than 50% more air (or oxygen molecules if you want to be picky), but he is still getting roughly 50% more power so he can't be too upset with the results. That was my point; I'm glad he understood.

I just noticed that you Dyno chart was from a Dyno Dynamics Dyno..... That is a really tight dyno... Actual numbers shud be higher...

I'm picking up my car tomorrow. We were able to extract a few more horses. I will be driving the car as is for a while until I figure out phase II of the project. That will be ingnition, even bigger injectors, a switch from electronic throttle, and a single tip 3.5" straight thru exhaust. WE'll see for now I'm happy with the power it is making. I took a ride on the car today and it felt really strong. It is much different than the Greddy turbo in the sense that boost seems to come on much higher in the rev range at around 5000 rpms. I'll know more when I actually drive it myself tomorrow. Here's the dyno graph.

first of all, i like the way u have the turbo sittin up front to the side of the car. but how did u do that? was there enough room underneat to make a custom manifold and downpipe? also if i saw the pic correctly, did u take off ur air pump?
