Rep for you Phunk thanks for taking the time to answer all my inquests.

clearly a lawyer in the making... :roflpuke2:

Phunk are u using a boost controller. If so, which one? Sorry if it was mentioned before, I missed it

Almost, in my final year of school....ever. Though I can't lie leaving a college campus and the college girls will be a bit sad. Hopefully I'll be starting my own Z power overhaul post law school.

currently i am using an HKS EVC5 i think it is. its the one with the silver housing and blue backlight with white digits. i like it a lot. I yanked it from my 350z lol.. i installed it in that car when it was the latest greatest.

I dont know if any of the newer model controllers can hold boost better or not, I havent played with them. Just like in my 350z, if I want i can make the boost have a rapid spike of a couple psi if i mess with the throttle just like, like stabbing it on/off when its already at full boost... that will usually make it spike to 10-11psi just for a very brief moment, like a tenth of a second, but enough for the peak hold to catch and save it. I dont worry about it.

buuuuuut i am sort of eye balling the new EVC. i need to compare the dimensions on it and see if it will fit in the holder i just busted my *** making for my old EVC. let me post a pic of that in a moment

added this pic to first page to show my boost controller

heres a video from a couple psi ago



k fixed, thanks hazzazi

There you go :driving:

sure, if you just click on this link it will tell you exactly how to do it..

good luck http://www.the370z.com/announcements...st-thread.html

heres a 35 mph - 145 mph at about 8.5psi.

LOL my boost controller display falls out on one of the shifts cause i hadnt used any velcro or double sided tape to secure it yet since making that bracket for it.

sorry for the poor video quality, i took the video with the go pro suction cupped to my side window. i edited it ghetto with some freeware that i downloaded because i actually recorded an entire 20 minute beat down session with the car, but then figured i better not upload the entire thing if want to keep my car and drivers license.

if you recall from your own 370, the speedo digits are in 20 mph increments, so the starting point is roughly 35 and you can see i let off at about 145.. you have to play it full screen to really see anything. sorry.



you can see these cars are pretty quick with a little boost on the stock motor. but the speedo starts to move pretty slow by 100 and above... needs another 200hp or so to have the excitement it needs!

Nice Z and some people say that the Greddy turbo is laggy....lol:tup:

there is no relevant lag at all. sure smaller turbos could come on even sooner, but these are already a bit much. what you cant see in the videos is that i cannot completely floor it until part way into 3rd gear. the car has 305 30 19 RE11s at about 1.5 degree camber in the rear. later on ill upload some videos of wagging the tail around. if you just roll into half throttle second gear quickly, it just immediately lights them up and you can wag it all around.

great build...but I hate you for giving me the boost bug itch :D

dude, your name is boost lee!!! lol

awesome videos! especially with acdc playing

Me too but it's price makes me wonder if I really need it. About $750 shipped plus whatever customs will charge you since its shipping from Japan. I was about to pull the trigger on the simpler EVC-S but now Im not sure.. again lol

Your car is FAST. Wow.

hey phunk, not sure if you have them already but here are the dimensions on mm for the new EVC.

thanks i will check on it today... gotta pull my car in the bay in a few anyway to work on this fuel starvation product

I giggled like a little girl when I saw this :icon17: Impressive, love the sound, not loud at all but enough to enjoy the sound of a turbo(s). What's your opinion on the gear ratio now with the boost? Could be longer?

:icon17:

Sweet videos! Man I'm begging for more boost! :D

Phunk:

Your vids just made my day. I just got out out double digit months to go. I can't wait to get back to feel the Greddy experience. Man it revs fast............and it sux out here.....

guess ill have to take another video or two for you guys. im going to go grab my Z in a little bit, its gorgeous out. I have driven it every single day as my only car all summer... Friday i bought a POS 1984 325e as a toy/DD/winter beater, so I spent the weekend with that car and left the Z at the shop. ill see if i cant find a few moments to get some video from outside the car too maybe

What did you ever do with your 350 you had?

Sold it a few weeks to a guy I know. It's parked in the street behind my 370 right now

Lol I have another car thats boosted to keep me from boosting the z, but this thread doesn't help!

after pulling a lot of 600cc bikes, tonight i decided to up it a notch. a buddy has a 08 gsxr750 with full exhaust, intake, and power commander... and not sure how much it makes a difference but hes a smaller guy, probably 140lb. we went out to pretty much the middle of nowhere at 1am and we did about 10 pulls total from various speeds.

i bit off a little more than i could chew with this bike. starting in 2nd gear was just forget about it... between the bikes power to weight and me not even being able to floor it and trying to fight wheel spin, it was just instant death. i wouldnt catch him from this side of the land speed record. We were on concrete and it was about 75 degrees out so i had good traction and down a little on power from the warm evening, so hooking up in 3rd was no problem. when we rolled out in 3rd, he would immediately knock me 2 cars, then start casually putting distance on me. somewhere around probably 120 it would even out and shortly after i would start trucking up on him... but i didnt make up the distance and pass until 160mph... although i did cruise by pretty steady cause i had some decent space to build speed on him once the bikes aero started to screw him. i guess time flies when youre having fun because i was super shocked to see that speed, i had not realized at all that we had been in the pull for so long. i dont think i have taken the car so deep into 5th before

starting in 4th was a lot more in my favor. if we hit it at like the exact same time, he was getting an instant 1.5 - 2 car on me and then just barely inching away, then we would be super close for a while, and i checked the speedo when i finally crept past and it was 140. so a lot better.. but really this car can only pull that bike on the top where the aero is fighting off his power to weight.

we are going to try again in a week or two, im going to swap on some fresher tires and do a little street tuning for some more boost, and we are going to try it on a cooler night. i think i can squeeze out another 50hp and make all the difference... i think that should get me in the realm of staying side by side for 3rd gear and then pulling off my FINISH HIM somewhere in 4th instead of taking it to friggin ludacris speed madness just for the sake of letting the aero take over and put the Z in the lead. One thing is for sure, its going to take a really sticky tire and at least 700rwhp to even bother with a late model liter bike.

Did you happen to notice how high your oil or water temp go to? I bet is was still a fun night:driving:

I only have the stock water temp gauge which doesn't seem to ever move for me... But it's probably not the most instant reading. I'm sure it increases a little but not enough to bother the gauge.

My oil temps weren't really getting in the way. Probably a lot of airflow on the cooler from the constant speed.. Some runs were back to back but I don't think I saw over 230. I was coasting down rather than braking which helped... I had to because after the 3rd pull deep in 5th, my stock sport brakes were over it.

Awesome

From datalogging with UpRev, the water temp gauge stays at 2 dots to the left of the center until it hits 106C. Then it moves to the right one dot and tends to move one dot every 5C after that.

Charles any updates?

Nothing of significance. I am still daily driving the car. I havent been doing as much cruising lately, last week was a solid week of rain here although the weather is currently gorgeous again. I am somewhere over 7000 miles on the setup now, no problems yet! I still wish I had the motivation to pull out the laptop and do a little more tuning and check higher boost on the dyno. I do let it hit 9-9.5 psi sometimes, i would be curious what it makes for power there because now 7.5-8 feels slow LOL... funny how that works with every 1 psi.

i am starting to get pretty desperate for new tires though. Trying to decide if I want to really order up the R888s right now or just wait until spring. I sort of fear spending the 800 or so and then having the put the car right into winter storage

once the car hits storage is when you will probably see me take the time to work on my thread some more lol. i havent had the drive that i thought i would to put every thing in here!

Phunk, I'm starting to see a few HR's running 51x whp and 42x tq on stock internals, do you think the VHR has similar limitations? How do you think the VHR would respond to a simple set of drop in forged pistons perhaps running stock compression and FI?

there is really only one way to determine the limits of the short block. i would like a little bit more, but if i dont get some stickier tires on it wont do me any good this side of 80mph. I honestly think that will stand for most people. I currently run the RE11s 305/30/19 and the poor things just do not stand a chance. Not many people are willing to run a more aggressive tire than that, so I think the 500-525rwhp range is probably a good target for people.

I would like to grab a nice set of 18x12 and put on some 335 drag radials or R888, but I am not a huge fan of spending big bucks on a custom wheel just to drag race on occasionally. If anyone knows of a cheap *** 18x12 I could use, let me know! With that type of tire setup, could probably handle a pretty significant jump in power.

I DO still want to turn up the boost on the dyno and see whats going on, I am starting to feel like perhaps 600rwhp wouldnt be all that big of a deal on this engine, especially for someone who doesnt constantly beat the snot out of the car.

For pistons, I plan to run a 10:1 piston, but i wouldnt leave the rods stock, they should be upgraded too. I think stock compression would work out, but its impossible to speculate where you will start losing stability in combustion without trying. i would hate to put in some stock CR pistons and find myself having issues running into knock just past 600rwhp, a number that i could have run on a stock engine. I think I will go down to 10:1, it shouldnt destroy the natural characteristics of the engine noticably and it makes me feel like i may get a bit more headroom. But who knows, this engine is really great... perhaps people will find stock CR allowing them to take power very far. I suppose the E85 I run may help with that?

phunk, for wheels look at what the Mustang guys run at the drag strip, they have the same bolt pattern as the Z so if any of those guys run 18x11-12 they are usually cheaper wheels. Those guys hate spending a lot on wheels just for drag racing also.

not a bad idea really i will take a look and see if i can find anything

That's actually what I did. I bought some Mustang Saleen replicas that are 18x10+22. I couldn't find anything wider, unless they were 15" or 16" wheels.

Ya i definitely need to dig up something wider than that if I am going to use an 18"
