Great driving. Great numbers. Congratulations.

BTW 1.91 seconds on street tires really pisses me off.

 

Glad you qualified that. I was with a TT owner at the track last weekend that was ripping good ET's and good MPH and would leave you ST guys for dead at the drag strip (or on the interstate). J/K

BTW, why do the single turbo cars trap so much lower than the TT cars? You all seem to be running ~ the same boost. I've been to the track with two different local TT350Z's (one Greddy, one APS) and they've both trapped over 118 consistently.

Either way that's a nice run, especially on 19 inch street tires.

 

hey gnxs, what were your times? 60', 1/8 et/trap, 1/4, etc?
And how much RWHP on your greddy kit?
I'm hoping california speedway opens up this week or next week so I can finally do the 1/4.
Also, what are your launching techniques? (specificially)
I got my 60' down to 1.9 but that was after 3 passes and the tires being REALLY warm.

 

Sorry if I wasn't clear. I've been to the track WITH two different TT350Z owners, Brian and Charlie, I don't own a 350Z myself.

Brian posts here (BriGuyMax), and I think Charlie does too (Phunk). Brian has an APS kit and posted his times from last Sunday in another thread (with his timeslip I believe). Charlie has a Greddy kit, but his car is well beyond stock now.

 

Thanks. The launch was at about 2800rpms and just feathering the clutch.

Yeah, I don't really want to start a ST/TT thing, but I'm confident I could run 11.8s or so with this setup, some good drag radials, and a little practice. I'm buying some ET Street Radials later this year and will have to get some better times for you all then. I'd be willing to bet I'll be running about the same ET's as most TT owners with much less power and a lower trap. That is, until I go with the TN stage 1.5, or stage 2 with a built motor.

I haven't decided if I want to go with 1.5 or just build and skip directly to stage 2. We'll see.

 

The reason why is because the two smaller turbos flow air more efficiently at lower boost levels, which is why TT's make more power out of the box on the stock block. If you really want to pull mad power out of a ST setup, you're going to have to crank up the boost (and build the motor).

ANOTHER reason why my car is trapping a bit lower is due to the fact that it is on the reflash, which is tuned VERY conservatively past 5k rpms. Timing is actually retarded quite a bit up top for safety reasons. With the TN stage 1.5 kit (EMS, injectors, etc), I'm pretty sure I could pull 20-30whp more out of this kit just my tuning for more top end power. Right now, my car makes great midrange power on the reflash (daresay, more than Alberto's ), but power tapers off on the top end a lot more than it should due to the conservative timing.

 

11.8 at 113 would be possible with a low 1.6 60 foot mark. that would have to be done on slicks. im sure its possible but that would be a hell of a launch. you know.... kinda like my launches you should come over to orlando speedworld and run one night man, or i could maybe trailer my car over to bradenton. ( i am not going to break my car there and have to get it towed home)

 

Yeah, that is with a little more practice. I should be able to get my trap up to 114 with the power levels I'm at.

Unfortunately, I haven't been able to find any slicks that will fit on my stock 17" wheels, so I'm going with the 275/40/17 et street radials.

I'm probably going to head out to bradenton a few times this summer to run before trying for a new best on the ET street radials this winter. Maybe I'll be able to make it out to Orlando one of these days. By then I should have an RPS clutch/flywheel setup too...

 

it all depends on how the track is hooking. that day we were dumping at 3500 or 4k and it was hooking like mad.

 

yeah you wont find any 17 inch "slicks" but if you grab some 16 or 15 inch rims you wont have any problems.


drag radials will work well but not like slicks.... i might ride out to bradenton in a few weeks. i will pm you if i go

 

you all seem to be pulling off some really good times.

what's the average 60' on street tires. anyone hit 1.8's with street tires?

 

my friend here pulled a 1.89 on stock potenzas the other night

 

Craig has the ability to trap higher. I was trapping nearly 115 and he's running 1.5psi more than me.

 

Thanks....and yes, your explanations make sense.

 

When you start cranking the boost on the 60-1 you start to get well out of the higher efficiency islands. At 15psi on a VQ35 you're flirting with the edges of the sixty-dash compressor map running in the ~68% efficiency range, 70%ish in the meat of the powerband between about 4800 and 6000. Nine PSI on a VQ35 with a 60-1 compressor is about as efficient as it gets, higher than that and you start to get into the situation I described above.

The 60-1 is an ill-suited compressor for a VQ35 wanting to make big power, it will create more heat at any given pressure ratio than would say - for instance a T61 - which has about exactly the same ultimate flow limit, but it'd be flowing that air more efficiently thus creating more hp and less heat at the same boost level.

At 15psi for instance the T66 is a far better fit than a 60-1 is, and a T61 even is quite a bit better than a 60-1.

 

Tuarran-Ive heard from a reputable Tuner that TN actually isnt very conservative with the timing up top as some of you may think....

 

the best you will find are the bias ply et streets, not the drag radial. I was yanking my fronts slightly with them on my stock cobra wheels(17x8)

 

beddow? i should be out next week, but on street tires, im still waiting for my new wheels.

 

beddow is eric, i am jeremy, i want to go to the track next week but i dont know if i want to risk breaking anything right before z dayz and our track event june 3rd...


pm what day you are going. i might go for the hell out it. i got my 28 inch slicks. i want to see how all that pans out...

 

i was asking who cut the 60's on street tires and I'll shoot you a pm
