Just so you don't have to go all the way to the 2nd page of the other thread here are the build / set-up pics:

Summary of the set-up is as follows:

Bone-stock LS9 (Including stock cam)
IPS Twin-turbo Kit featuring HTA 35R Turbos & Tial 44mm WG's
IPS Custom Fuel System
IPS FMIC Kit w/Tial BOV
IPS High-output Alternator Kit
RPS Triple-disc Carbon Clutch
RPM Level 5+ Tranny & Rear-end
PFADT CF Driveshaft
DeWitts Aluminum Radiator
LS7 Engine Accessory Parts

No dyno #s w/o the owner's permission but I will say that it made as much power at 7psi as it did with the stock blower and many bolt-ons did at 16-17psi

At 15psi and pump gas (No meth) it has made more than any other LS9 ZR1 we have ever heard of E85 and larger injectors are going in on Friday and it is only going to go up from there

Dyno graph's / Vid's and further info to come!

Looks Great!

Is there any room for a pair of 67mm or 71mm turbos?

0IPSjeff

Since the plan all along was to tune it on E85 the owner doesn't care about posting the pump-gas #s so here they are:

Prior to the Twin-turbo conversion the car had a nice assortment of bolt-on's and a tune. At 16-17psi it put down a best of 627rwhp on our AWD DynoJet and an average of 615rwhp.

With the turbo kit on base-boost (7psi) it put down 626rwhp on a VERY conservative tune and just over 700rwhp at 10psi and then 850rwhp at 15psi

Larger injectors will be here Friday to run E85 where we fully expect to break into the 900s at 15psi and mid 900s if we run the same boost levels it ran before on the stock blower set-up. Stay tuned!

That is freaking great.. 850 rwhp on pump without headwork or a cam. Makes me think... How differently does the car drive so far?
is the powerband still heavy thick even down low?

Any plans of meth to combat IAT's or are you going to run E85 solely?

Great numbers!

0IPSjeff

We actually won't need to add meth at all as the IAT's have been very good (For an Air-to-Air Intercooler) even on pump gas due to the lower boost pressures. At 10psi and right around 700rwhp they are actually very good The E85 will be good insurance above 13-14psi or 800rwhp.

My tuner is the only one who has driven the car thus far and at 10psi he just said the car really REALLy needs tires lol

It obviously isn't going to have that huge spike in torque you get from a positive-displacement blower but the power-band is still incredibly flat / broad. From 4k and up there is no comparison at all

I will get some dyno graphs posted soon

Looks nice. How did you route your inlets and where did you mount the air filters.

What are the prices on ur turbo kits? I dont see them on ur website... Nice setup on the zr1

Incredible workmanship

0IPSjeff

I will have pricing and included components and such up on the website soon. For the larger turbos we are only going to install them in-house until we have a solid wholesale network set-up of shops capable of installing and tuning them well. The clearances are so tight that an owner trying to install one himself in a garage would HATE us lol.

There really won't be many options aside from turbo choice which will consist of the following:

1. 3076R w/1.06 A/R in Billet or Non (1000-1200HP)
2. 35R w/1.03 A/R in Billet or Non (1200-1300HP)
3. 35R+ w/1.03 A/R in Billet or Non (1300-1600HP)

Any specific questions just email me at: sales@ipsmotorsports.net

Jeff,

Honest question here:

How can a 6.2liter engine make more power per pound of boost than 7.0liter engines using similar components?

Also, 620rwhp doesnt sound right for a pullied ZR1, but you already mentioned you're dyno is convervative. Now, how is the car making much more power at the same level of boost? I understand turbos are more efficient than blowers, but turbos have their own restriction as well (exhaust restriction) whereas you can run a 2" header on a blown corvette. Point "many" are missing is that turbos are also not free power, again I thought maybe 60-80 more rwhp based on efficiency alone, but 300+ rwhp? How is that possible.

Again, this is an HONEST question, and im looking for a technical answer here

Jorday

How much power do you think a pullied ZR1 should be if 620 doesn't sound right?

zeshawn

that would depend alot on what pullies/ boost level the car is running, however I can tell you ive seen more than one ZR1 hit 600rwhp with just headers and tuning.

Taylor from Dallasperformance did 680rwhp from a pullied ZR1 with headers, custom CAI, heat exchanger and tune. and 700rwhp with race gas.

venomws7

Awesome work IPS 850rwhp on pump gas with stock LONG block is sick...
We need some videos atleast a dyno and prove why the car needs a better tires!!!

zeshawn

I agree, I dont beleive the car needs better tires until I see some recorded evidence

0IPSjeff

It is up and running on E85 now but it still takes quite a bit of additional tuning before we are ready to do full-throttle pulls on the dyno. I will record a few of them for sure. We can record a few "Ride along" type vids out on the highway once the owner arrives to pick it up

If another 10-second C6 shows up out of the blue for comparison then it might be an even better vid
Jeff

0IPSjeff

How many of the 650-700+rwhp cars trap over 140? The track doesn't lie so on my dyno a 627rwph ZR1 = 139 traps. You can make your own assumptions as to what the same car making 850-900rwhp will trap
Jeff

0IPSjeff

We are making similar power as the 7.0L / Auto TT cars due to to two things:

1. MUCH better turbos
2. 6-speed Tranny in the ZR1 (Which is more whp friendly)

The crazy thing is the turbos are not even in their "Sweet Spot" just yet so it should REALLY start making good power in the 16-18psi range
