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?
