If you don't want to cut holes. Think you will end up with a new hood.

Went by to get a 5000lb winch and they were all sold out. Just my luck. They were on sale too.

I got my new CSF radiator and 2 more liters of OS Giken diff fluid today from Z1 Motorsports. I didn't pay for Saturday delivery. Now that's what you call service. WOW.

After Bob's little track fiasco, I am having all of my oil lines upgraded to XRP Racing lines via MA. They are already using them for my fuel system they are building.

My car is at MA-Motorsports as well. They built the sleeved block with their design 11:1 CR Pistons and Carrillo H Rods. JW Stage 2 exhaust cams. CJM Stage 2 Fuel Rails CJM Twin 450 Fuel Pumpsl CJM Intercooler E-85 flex fue AAM Stage 2 EFR 71/63 Turbos with external waste gates AAM upper intake AAM oil pan Ecutek Tune Quaife LSD with MA-M diff cooler OS Giken twin disc clutch Dyno'd at 667 rwhp on their Mainline Dyno which reads 17% less than the more common Dyno Jet. This translated to 780 rwhp on a DynoJet Calculating BHP using Fuel Flow it came up to 1K BHP. (this factors out to 850 rwhp with a 15% hp loss due to the drivetrain) 4 boost settings on the EVC6 controller = 13 psi spring pressure | 16 psi | 20 psi | 25 psi | My goal was 800 to 850 rwhp so I'm happy with that. The car is still streetable and reliable. I did go down to test drive the car a few weeks ago to shake it down and find the little bugs that need attention. The car is awesome so far - but the turbo's smoke due to poor oil drain - the location and angle of the drain from the turbo's into the oil pan does't allow for sufficient (gravity) drainage. MA-M will have the car for a little while longer to fix that and to put in a roll bar. Will be following your build with Great Interest !!! |

prior to that it was at AAM for almost 2 years as well ... AAM blew the built motor and tried to cover it up. That's why it's now at MA-M and I Highly recommend these guys. You've probably seen my car down there ... it's the PG one with the 17" wheels and big tires. |

The location of the turbos aren't conducive for efficient oil drain = turbo smoke If you have the EFR 71/63's you definitely need the larger I/C and may want to go with external waste gates because they 'modify' the IWG actuator linkage by bending it for clearance. I've been advised by MA-Motorsports that this can be potentially dangerous. Good Luck with your build !!! |

Phunk's friends (Can't remember his user name) car made 818hp at 18.5lbs of boost on a dynojet with his tubular exhaust headers and GT3076 snails. I am very curious to see how mine does.
|
Here his build is.
http://www.the370z.com/forced-induct...0whp-ease.html He also has the 1/4 record at the moment. http://www.the370z.com/forced-induct...rag-build.html |
The more I look at Streetz's dyno graphs I think we have a restriction on the exhaust side. I wish someone would measure the restriction in the exhaust manifold compared to the boost psi. This would tell us the ratio of backpressure to boost pressure. When it get's out of whack and is not keep close to a 1:1 ratio bad things will happen. Phunks's tubular exhaust manifold and his turbo size/exhaust housing AR must be on point to have made what it did on only 18.5 psi of boost on a stock engine. There is something to learn here. The more HP you can make on lower boost pressure is a big positive.
|
Well crap. I looked up the Stage 2 Xona Rotor turbo's and they are only good for 800hp at the crank. At a 15% drivetrain loss that would be 680hp at the wheel. On the mainline dyno this would mean only 564hp at the wheel. Looks like I will be 86hp short at the wheel. We shall see if my calculations are correct. Not sure if I want to react and get 2 bigger turbo's or just stick with what I have.
|
I need to think about this.

How the heck did Streetz make 818hp on only 18.5lbs of boost and a stock block. Seb had to make it happen via timing. I am scratching my head on this one.
|
Definitely had some good ethanol fuel in system; notice AFR readings :ugh2:

They stopped increasing the boost when there was less than 10 hp increase per pound of boost. He said that both the turbos and the fuel were maxed out...so it is what it is. Forgot to mention that I'm running the ID 1300's (functioning at 85% duty cylce) since it will primarily be a pump gas car (few E-85 stations close by me in N.J.) I probably won't have the opportunity to run it at 25 psi too often. I will inquire about the specifics on the boost near the end of the week when I check on the progress... I'm more interested in getting the car finished up - the small details can be time consuming. Since Daelen left a few months ago (he was the go-to guy) and they've moved to a new space in the same complex - the workload has increased and info has been slower in coming. Jon is now wearing a couple of more hats. They did a dyno run before and after the installation of the CJM Intercooler but that was a few months apart but the results were pretty much the same on the E-85. As Ray has always said - don't worry about the numbers - the proof is in how it drives. |

I already made the decision earlier tonight. I am going to stay the path that Daelen and I decided on in the beginning. I have spent enough. We shall see what I get. If I can make 622-650hp on their mainline dyno, I will be happy. That will be 720-750hp range on a dyno jet.
|
One thing is for sure. I will not run out of fuel. I will run out of turbo first. I have looked all over the place and have not found a Fast Intentions stage 2 turbo kit on a built motor with 11:1 compression. We will all find out where the limits of these turbo's are.

:icon14: Wow you’re up early :ugh:

You should be good to === GO === Daelen talked me in to a few things to keep my build within my goals and budget but without going overkill. Daelen was a fan of high compression - he built his own 370z NA with 12.75:1 CR. I had originally wanted to go 10:1 and was considering the 4.0 L stroker. But that would've doubled the cost of the build and added another 6 months or so on to it as well. |
