Stock GSR dyno #'s, anybody esle use larger turbo's at low boost??
So here's the deal, took a customer's car to the dyno yesterday and finished with 262whp (I forget the tq) @ a logged 7.7psi on a stock B18C1, but has anybody else run something like a 60-1 at such low boost levels before? I was expecting quite a bit less than that from this turbo considering such a small boost figure, but I was relativley supprised by the numbers. Any input?
Setup:
Stock B18C1
Stock P72 head/cams
JG Victor X IM
SFP manifold
60-1 w/ .48 hot side
2.5" DP - 3" exahust
450s
Stock GSR fuel pump
Ultra-conservative tune (higher milleage motor)

.48 A/R huh.....you have a dyno sheet so we can look at the power curve? I am curious as to the spool up on it. I do not see why this is a high number....sounds about on to me.

As far as I remember 60-1 is a pretty high flow turbo, so low boost will give you a lot of gain. You don't wanna go beyond that much whp if your engine is bone stock. As an equivalent, my setup is similar to yours, but with t3 60 trim running 10 psi. gaining about the same whp.
you either go small turbo, high boost, or big turbo, low boost. I prefer small turbo high boost so it's more fun to drive, less lag, I got 7psi at 3200 rpm or so. What about yours?

Well actually I was quite impressed with the spool on this thing, if I remember correctly it was giving full boost at about 4k rpm, and this is without any kind of boost controller mind you. Drivability is great and the torque curve was basically a straight line from around 4500 to 8k, I'm sure to some extent it was due to a very conservative ignition map, particularly up top. I'll ask the owner to scan his graph so you guys can see it.
But with that turbo at that low boost, I wasn't expecting more than 240-ish whp really, but then maybe because of the smallish turbine A/R it's going to help it some especially in the mid-range.
BTW I also used a straight T3 on my GSR once (50-trim), loved the spool, it was SRT-like

the 60-1 will flow more cfm even at the lower boost giving the engine more power, I just built my engine around the GT35R hoping for 450whp @15lb

Well, the more you can make while pushing it the least.. sounds like a good deal to me.

Mia from Utah, bone stock GSR, FullRace kit, PT61, .84 a/r hot, P trim, Prostreet mani, 720CC injectors, tuned by Cort with Neptune put down 405hp on 10 psi.

the only issue here with big turbos and low boost is sometimes guys dont even gett into the efficiency range of thier turbos, i mean running an sc61@ 10psi just plain sucks. tune it well and run it up to 12-15psi and see the difference in power.

Re: (BLKTeg94)
Damn, only 10psi from a PT67 and it made that much?? Guess there's still pleanty of potential from running lower levels from larger turbos.

Yea that was actually my biggest concern, I mean don't have a compressor map for a 60-1 infront of me, but I'd assume it can't be terribly effiecient at less than 8psi.

true, seeing is a 60-1, whether t3, or t3t4 wa made to run in the 18-20psi range, they are very surge-ish at 8psi
at that point i would downgrade to a t3/60-1 and get killer *** spool and in the efficiency range

***Uncorrect on that PT61*** She ran an 11.5 hit 99 mph at the 1/8 slamming on the brakes at the end hit a 11.5 doing 108 mph. was an easy low 11's run. **** is insane.... Most efficient turbo set up we've seen so far.

Re: (jdmtegra666)
thats the turbo i got for my built LS "t3-60-1"
So far my friend got the same turbo in a ls teggy and with stock exhaust pipes hit 8psi at 4300ish. OMG does that turbo sound ******* bad-*** spooling up!

I am no expert tuner, but I know a thing or two and believe me I have done a shitload of research on GSR turbo setups. Anything I have seen has made 50-100 less horsepower on the same psi. Its highly unlikely to happen.

I'd have to agree. so you're telling me if that car was to run more boost, let's say 25psi, the car could make 1000whp?
tuning is essential but then again, you can only do so much.
