Here's a typical Powerlab dyno at 8-8.5psi (https://my350z.com/forum/forced-indu...install-4.html).

This will be a perfect benchmark comparison as a 6162 very similiar in size to a gt35. So somewhere in the 4-410 hp range on a dynojet is expected from your kit at the same boost levels

remember thats true DD numbers...
injected reached 450whp uncorrected DD numbers at 10psi....
its surely its a nice turbo...if it compares similar to the gt35r it a nice choice. for turbo

I'm curious to see how different the power/torque curve is shaped (if at all) with the new BP turbo. Considering the changes in piping (not being the usual 'U' shaped + leading up to the front mount turbo). The shorter piping feeding directly into the turbo and piping diameter on the charge side as well as the exhaust side will be the other drastic changes when compared to other kits. All this may play a factor in how well/quickly the power comes on. Looking forward to the results. Good Luck.

Hey Str8dum is this plot below from a Rev-up Motor? Any idea? I believe Boosted is building up the kit on a Rev-up model Z. Just curious to know, so we can more accurately compare apples to apples.


EDIT*** Disregard...Just noticed at the bottom this is from an '03 350z.

450 at 10 psi is nice, do you have a link to that info?

I have a few items from another turbo build and was wondering how much for your g35 kit without the turbo, injectors, ems.

I am not really worried about comparing the max power here. We all know that the max hp is directly proportional to tuning. My timing map is very conservative, and I don't plan on changing that. The A/F will also remain in the mid 11's, but I am sure that it will make good power.

Also, this being a JB turbo and powerlab using a BB, the spool will not be a true comparison. I am however certain that this setup will boost quicker than any other ST out there. This is due to the reasons rrmedicx mentioned. The piping to the turbo is larger, shorter and does not contain a single 90deg bend, let alone two 180's. The down pipe is much shorter, and the FMIC is vertical flow so that will play a roll as well.

/\ I'm more concern on the power curve than max power. I haven’t really read every pages but do you have any dyno? I'm sure you have one since you are already selling the kit.

I had one uploaded on my original build thread that I accidentally deleted. Now I can't find the original at home. My kids like to draw on just about anything that is white, so it may have ended up in the garbage.

I can tell you that the torque curve was very good.

I will get the car on a dyno ASAP.

what rpm did you hit your peak TQ or what rpm did you hit full boost (and what boost)?

do I need more posts before you answer my question

he stated before somewhere in the thread he will be selling only full kits at this time.

its quite easy to get a boost curve from a powerlab kit as well. Make sure you post your boost curve as well.

I didnt post that dyno for max power, i posted it for the nice trq curve.

Ha, found the old dyno in my photobucket.

So, this is with 4psi (acording to the Haltech log) of boost with an old school Garrett T3 60-1 .63a/r turbo. Max timing was 17deg (basically base map from Hal) and my a/f here was 11:1 that I do remember for sure. I am not sure why I have a flat spot on the torque curve..but here it is:






Oh, now that I think about it, this was done while I still had the 2" crossover pipe. That got changed to a 2.5" later on. Don't know how much difference that makes, but worth mentioning. With the 2" crossover my a/f ratios were different on each bank (dual widebands loged) When i went to a 2.5" they evened out. The 2" bank was running richer, so not enough flow through the exhaust where the othe bank was 2.5" right from the header flange.


This was also with a 38mm Tial wastegate. No boost creep, I will use the same setup (minus the 2" crossover) just to make sure there is no problems on this (6162) better flowing turbo.

That boost kick a little late for just 4psi. WS spring didnt help.. Can you go to a dyno and maybe use a boost controller? I hit 9psi at 3700rpm with peak TQ around 3900rpm with just the crappy Utec BCS.. and I hit peak TQ at 4500rpm on 5psi wastegate spring with my STS. You should be able to do better…

17* is not very conservative timing. 12-13* at WOT is conservative. I was running 17* with my more aggressive meth tune.

but it will be excellent to see some updated pulls to compare with STS and PL.

Simply put, I may be able to tune a vtwin power commander or a 502 Merc on our boat, but this Z is amazing in the complexity of all of it.

Hal @ Injected will be retuning my car yet again.

I am looking at taking the car in on Thursday. I will shoot for about 8.5psi (BC) and see how things go from there. So look for that next week.
