Curious

1. What would you guess the following setup would make "approximately" tuned for 91 and 93 octane on an AWD dyno -

EVO IX w/ WORKS TR-340 (with Cosworth Cams)
add WORKS o2 housing
Upgraded injectors
Upgraded fuel pump
Upgraded actuator arm
FP Green Rabbit Turbo

Would the above WORKS TR-340 kit with Cosworth cams and a 91 or 93 octane tune with the Green Rabbit turbo and o2 housing put the car into the mid 11's, yet still be a nice daily driver?

2. Also, what is the word on the WORKS TR-440 package that was being talked about last summer, any updates?

3. Lastly, have you done a TR-340 package on a IX with a GT30(R) or FP 3065 that is a nice daily driver and what kinda of power was it making?

My end goal is putting together a setup that is a maximized daily driver.

 

Dude, I'm thinking the same thing!

Hello, Oliver? Kirk? Bill? Pete?

 

I'll consult the magic techs and see what kinda answers I can pull. The TR 440 is on the back burner for now until we finish completing our move up to Sears Point, and some other more pressing projects.

Thanks Bill, we all appreciate the time and look forward to a response.

 

Ditto! Cough! - (umasi) - Cough!

 

WORKS typically upgrades the fuel pump with the TR-340 package on the IX and we see outputs on the DynaPack in the 290-320+ range with 91 octane. The FP Green (along with injectors) has shown a range of an additional 15-30+ on top of the TR-340. Most are opting for the WORKS O2 housing with the Green as its been shown to bring another 10 or so to the table (again, similar boost levels ~21 PSI) on 91 octane. You probably won't need the upgraded actuator on pump gas.

Getting the car into the 11's will depend on the driver and the clutch/flywheel involved as the power should be plenty. At this point, you're still visually stock under the hood and retain near-stock driveability with drastically improved performance.

In general, the GT turbos and daily driver don't necessarily belong in the same category. Not saying it can't be done (as it has time and again), just that you lose some aspects because of the size of the turbo. Lag increase/spool rate decrease means your downshifting to pass on the freeway and/or up hills whereas before you could just roll into the throttle. If you want to minimize this, I'd look at the IHI turbos--broader and earlier powerbands. Under the hood changes dramatically as the external wastegate, etc... now stand out as definitely "not stock." Either choice increases power to that next level, but shifts the powerband further up the RPM scale.

 

Jamie,

I'm wondering if it's not time to add another "evolutionary step" to the WORKS catalog of performance packages (hint, hint). Let's hear some details on the "next level" - 400 awhp - pump gas only - factory ECU controlled - "WORKS knows how to build a BEAST" - package of upgrades. Full-race twin-scroll ex manifold, carefully chosen IHI turbo, injectors, even new WORKS intake and all the associated goodies.

Are you thinking what I'm thinking?

 

I am... That I should be the test mule... hahaha.

 

Which IHI Turbo are you talking about, do you have a particular model that can make another 40-50hp more than the FP Green for a daily driver?

Also, have you guys done a tr-340 package with a turbo like a FP3065 or GT3071/76? If so, what kind of power on 91 octane was that person making?

What would be your choice for the next step up in a turbo after the FP Green to match the tr-340 package?

Thanks.

 

Bump for some kickass engineers!

 

WORKS can spec out the IHI turbo that fits your driving habits/needs/wants/desires. There may be some compromise as we haven't quite found a work-around for the laws of physics.

The original silver WORKS car was running the TR-340 package with a GT3071 (or was it a -76) and the current Time Attack EVO started with the TR-340/GT35R. We've done customer cars with same/similar components and other GT-series variants. In the end, it's still a truck turbo whereas the IHI was built for automotive applications (F1 turbo-era anyone?).

We tuned the Time Attack EVO at a modest 21 PSI for this weekend's exhibition and I'll try and see what kind of numbers/curve it put out. This is the first time the car has ever seen a dyno, so I have no comparison of before/after, but we estimate in the neighborhood of 500HP on unleaded race fuel <30 PSI.

(Aside: I despise the numbers game and we typically don't resort to them for comparison of car/dyno A vs. car/dyno B. We strictly use it as one of many tuning tools and try to limit our comparison to same day/chassis/dyno/temp/barometric pressure/etc...)

 

While not officially grouped as a WORKS Performance Package, we can provide what your after. The IHI kit typically comes with the new tubular manifold and DP setup. We prefer the stock airbox on street-driven cars, but run open element filters on the track setups. Everything is (usually) readily available

 

For me personally 375-400whp is what I am shooting for as my daily driver WITHOUT methanol injection/NOS or radical cams. Can I get to those #'s with the TR-340 and say an IHI turbo you have in mind on a 91 tune, or will I need to go the GT3071/3076 route?

Thank you for the replies.

 

Great to hear!

I myself am looking for around 400-430 reliable awhp on 93 octane with the best possible spool characteristics ---- basically a time attack setup that lies just within the limits of the stock internals.

Few questions:

1) Which tubular manifold do you use with the IHI kit, and is it warrantied like Shearer's or FR's?

2) Which open element intake are you using? Is it custom, or off the shelf?

3) Can you opt for the ball bearing version of the recommended IHI turbo?

4) Do you recommend hard upper intercooler piping with the new intake tract?
(I assume your time attack car is running a mini bat. --- that's why I ask.)

Thanks, Jamie!
