t04b(v-trim) Bolt on Discussion

[1029TSG]

Just keep in mind before you pick all these wheels apart, they're all good for 500 HP. So feel free to squeeze a 50-75 shot of N20 if you so desire.

I have no intention of running nitrous. I do want a reasonably fast spooling turbo. By that I mean 3500-3900 full boost. What's the difference in spool up on these wheels? Can your supplier tell you if these are the T31 or T76 or whatever Garrett designation is?

I got the first gen wheel, it looks very open. I don't see any sign of clipping. Is mine the no-clip version? I hope I didn't get a laggy exhaust wheel. Can you have a look at

an let me know?

 

[nazthug]

i assume this is probably why mine spools slower then expected, i thought i saw a clipped wheel but didnt think it was because i wasnt told, and i just thought thats how it looked new, so i didnt bother, but with spool times in the 3600-3800rpm i figured i got the clipped one, although im not complaining at all, i cant wait to turn the boost up once the new injectors go in

I finally got it to break traction in 2nd from a roll at 16psi today with a gallon of c12 in it and a slightly bit more timing, it finally started slippin the wheels in 2nd gear(and i am NOT on stock tires, which light up on a t25 if you want, )



Just for some more figures, i logged my dsmlink today and got 30.5lb of airflow at 14psi dropping slightly by redline, i figured thats not too bad for that boost level on pump gas

See, this is what I didn't want anyone to do. Please dont over analyse which turbine wheel you received. They are all the exact same dimensions, they are all "76 trim" wheels and they all are rated at the same flow rates. These wheels just have slight variations to their design. One is not better than the other and to try and compare one's spool up to the other would be immeasurable.

 

[1029TSG]

Naz, that's better than typical spool up for a turbo of this size and flow rate. If anyone's spool up is different from another its due to other mods, weather conditions, tuning and so on. Spool up is primarily dictated by the size and design of the turbine housing and overall power is dictated by the size of the wheel.

 

[yo2001]

GEN3 wheel with Bullseye housing spools fine in my car. I'm seeing 20-23psi in upper 3000rpm. in 3rd gear. 19psi in first gear readline. From 4000rpm up, just hang on for a ride. :laugh:

The spool in my car better after I tested for boost leaks and fixed the boost leak.

dont worry dave, cause when it hits, man it hits hard, and pulls considerably harder at 14psi then the 16g did at any boost, even 22psi...

i am very happy with the power, and cant wait for the new clutch to really put the power down for once

I ran a fairly stock srt4 on the freeway at 12psi and was slightly pulling on him

 

[1993eclipseGS]

I'm still very happy with my turbo, When boost hits.. Man does it hit hard

 

[RavenX]

I envy you guys so much. If my 7bolt didn't go i would be as happy as all of you I have wait like a month and half before i get the car running again :thumbdown I just bought a built 6bolt with ross pistons, scant rods and some other goodies so i can't wait to throw the turbo on it and tune the hell out of it

 

[questhe]

Well sorry,
I associated the mention of using nitrous with draggers that use really open wheels or large turbos and then use nitrous to spool them.

Sounds like I'll get what I need based on naz and yo said.

Since my wheel is more open than the 3rd gen wheels, I'll get more top-end flow!

 

[1029TSG]

Remember at full boost (top end), what doesn't flow through the wheel will flow through the wastegate. No, I wouldn't think you would need NOS to improve spool up just wanted to point out that the turbine wheel was "large" enough to handle a little juice.

 

[Coup D E'Tat]

David,

Did you get any more turbos shipped out? I don't want to be annoying, just anxious to get it

Thanks,

Jesse

 

[1029TSG]

I understand, we finished up 6 of them yesterday afternoon and I should have tracking numbers later on today. We still have 11 more to finish up this week so everyone's order should be filled.

 

[Coup D E'Tat]

Alright, cool.

Jesse

Hey, Naz,
Can you post a pic of the drain kit installed? Looks like I won't be using the supplied drain kit because it does not fit my 1G. I even purchased a few extra 1/2" fittings to try to make it work.

I am going to use the drain flange, then reduce it to 3/8ths and use a few brass elbows and pipes. I cut the stock drain below the bellows, and I am using crank vent (or oil breather) hose to join up the pipe to the stock bottom piece.

The suppplied drain line is just not flexible enough to make the bends required. If anyone got it installed on a 1G, please post pics or send them to me.

do yourself a favor and buy the bullseye oil drain kit, its awesome quality, fits very well(just make sure you use the 45* bend on the bottom, not top, ) and it will fit just right

its very nic quality, doesnt leak so far and is a direct bolt on

 

[rsunahar]

I basically made my own drain line.
The fitting hit the the front motor mount, so I clearanced the motor mount, but then the angle was still a little akward.

So, what I did was to just cut the line at a certain point, cut the turbo side of the stock drain hard line--keeping the bend, and slide the braid over the stock drain line with hose clamps--sort of like how people install AFPR, attaching the braid over the stock fuel return with clamps.


It fit much better and there's much more play for movement and what not.


So what I have is the stock hard oil return on the pan side with the 70 or 80 degree bend, and the braided line clamped over it.

 

[1029TSG]

Jesse, I have your tracking number.

your 99gst let go? Can i know what happened? I fear the day when mine lets go, i hope it doesnt though

did it totally blow up or just needs a rebuild? All i want not to happen is a broken rod, that happened on my old focus, everything else i can handle, 2 things i dont want, crankwalk and blown rod...

I really hope this engine stays together, i am trying to do everything i can to keep it together

How many miles did you have

 

[onegee]

1029TSG -

Will a Street core from JR (ebay FMIC) be enough to support a Vtrim (48 lbs/min version) or would the race core be a better fit?

 

[nazthug]

this is the IC i have and it works well

JR said its good to about 450whp....he is using the same core, but 3" taller on his 900hp 300z

 

[1029TSG]

As long as the flow numbers are higher than what the turbo is rated for. The V-trim is rated at 720 cfm at 1 bar.

 

[nazthug]

oh really....interesting

my specs in my IC

650 cfm @ 1.5 psi 78% efficiency at 60mph

how is that? Its rather small, 25x7x2.8 core

 

[1029TSG]

Might be a little restrictive but its not the end of the world. I think the Big Greddy FMIC is rated at 650 and I know guys that have made 400 hp with it.

 

[questhe]

I have not seen any standards on rating intercoolers. The rating will depend on the pressure drop. And the efficiency will depend on so many other variables, including ducting, ambient temp, pressurized temp, and total pressure. Now throw in IC sprays, WI, pipe size, octane, etc. and no telling what is possible.

I could see someone making 600 HP on a 400 HP intercooler just as well as someone 'only' getting 400 hp on a 600 HP intercooler. That's why bench racing is discouraged. Only thing that matters is measured results and experience. Theory is only a guideline.

oops < / rant off> <--didn't even know it was on!

Whoa i didn't see your post there Naz. I had a mishap on the highway cruising at 80mph where for some unknown reason i lost all oil pressure. I didn't take notice of the oil pressure until it was too late and so you know there goes the block. The block has 57,000 miles on it and i have no idea how i lost all the oil pressure but we are in the process of finding out because when i filled it up with oil again there were no oil leaks whatsoever so we are pretty stumped. Block is done in terms that i get rod knock at 3,000rpms so its useless to me. I already bought a built 6 bolt so am in the process of acquiring some small things i need since i already have a built 1g head and everything that goes with it. To top it all i have to send my turbo to dave because i have to make sure the turbo is ok since its oil cooled. The head survived so am grateful and i am sure the turbo did as well because theres no blue smoke coming from the exhaust but i want to have that piece of mind you know. Am sure your 7bolt will be just fine just try not to go over 420whp as that would be the limits in my eyes for a stock 7bolt and good luck
