HKS GT7460 GTII Original Turbine, tested at Iveytune.
As per the topic we have been doing testing of the HKS 7460 Bolton turbo for the evo 8 and 9.

The test subject is a 2003 Evo 8: Relevant parts are as follows:
Stock shortblock and head.
HKS 274/278 Camshafts, new design.
HKS Gt7460 Turbine, ball bearing.
3" Downpipe
Greddy Turbo back exhaust (TI)
AMS FMIC, lower IC pipe and upper IC Pipe.
AEM EMS, Iveytune Calibrated (HKS VPro was supposed to be installed we got lazy, will be done next week)
Walbro 255 LPH fuel pump
Prior to the HKS turbo the car made 380/380 on pump and 26.5 psi and ran 11.4@118-119 on pump fuel.
A camshaft swap was done from HKS 272 old grind to the new 274/278 cams which will soon be released here. There were slight gains as the power was similar but with increased spoolup. The stock turbo was again baselined with these cams and this was done so as to be able to compare one turbo to the next.
Turbo and camshafts have been swapped now and we have tuned it on Pump fuel to 26.5 psi, and up to 33psi on 100 octane unleaded sunoco GT fuel.
We have all the results and I will post them shortly.
Importantly, the turbo seems to spool as fast as the stock evo8 turbo, but also has the ability to make a decent amount of topend HP. The ball bearing cartridge which is HKS original design, will most likely increase reliability alot over the standard bearing cartridges.
The turbo comes with all the necessary parts, water lines, oil lines, and adapters to make this a complete bolton affair. The housings are noticably larger than standard fair.
This is the only bolton we have tested that actually spools the same as stock, if not earlier, I am not going to play word games, it spools the same if not better than stock but will make 460-500 wheel HP in the right hands.
Here are the Dyno results, this surely won't be for everyone but there have been alot of customers seeking just this kind of performance and it is now here.
On the first sheet with 3 runs. In order of increasing HP, the first run is a typical stock turbo run on 93 octane, next is the 7460 with 93 oct and 26.5 psi boost pressure, next is todays testing on 100 oct unleaded and elevated boost to 33psi on the 7460.
The next sheet with the individual run is 4th gear testing of the 7460 to see what it will do loaded fully, and easily achieves 500+ftlb of torque on a stock 2.0 engine.
Enjoy the weekend,
Sean

Does this have the "extension kit" or does that turbo outlet pipe come with the turbo itself? Does it bolt on to an 8 as well? If you consider its price vs a red or green with the 8 install kit plus oil line from FP it is right in line or a little cheaper for an 8 owner.

Wow! Those graphs remind me of 2.3 charts, with a O2 like Invidia or Titek, and ported intake mani/upgraded mani, ported oem throttle body/ boomba, ported oem exhaust mani/tubular, and e-85 or 91-50/50, do you think mid 500 hp number's are attainable? with what it's putting down on "your" dyno what do you think the test car will run in the 1/4?
