Gruppe-S goes crazy for Hello Kitty!

Posted by Gruppe S On Tuesday, November 30, 2010 0 comments
I just heard that McDonalds was featuring their new Happy Meal Toy, the 50th anniversary Hello Kitty toy for the girls. It is a really cool watch and there are 7 different variations so I thought I would have to wait til all the watches released, this was going to take time and frequent visits to the local McDonalds.

So I head over there to the Foothill Ranch, Ca location and happen to know the manager because my fatass likes eating there. So I asked which toys were available and she said that I could have all 7 if I bought them with a Happy Meal. So I ordered all 7 and the Gruppe-S staff got to eat Happy Meals minus the toy. (The Staff was a bit disappointed opening the happy meals and missing their toy)

BTW the toys are for my 7 year old daughter, I do not have a Hello Kitty fetish, but this should make her very happy. I will save the watches and just use each watch as a reward for good behavior.

Hello Kitty, My Melody, Chococat, Badtz Maru, Keroppi, Sugar Bunnies(white and beige)

Gruppe-S first and only to introduce GTR R35 billet piston

Posted by Gruppe S On Friday, November 26, 2010 0 comments
Gruppe-S Engineering is proud to unveil the first billet GTR R35 piston!

No cost was spared in the research and development of the most comprehensive internals solution for the true GTR builders out there. There are obviously great forged pistons available in the world, but we worked with the engineers at JE to introduce a piston that can handle the rigorous demands of extreme high horsepower applications.

Currently there are a few engines that are capable of 1200 horsepower, however the engineers at JE Pistons feel that these are the limitations of these pistons. Some engine builders have contacted us and have seen some piston distortion at those horsepower levels and have been looking for an alternative that can handle up to 1600 hp. Well the industry should be happy to know we finally have a solution for those looking to build the fastest GTRs in the world.

Well here it is, and hope everyone enjoys the greatness of this billet FSR piston just built for us.

These pistons are designed from a billet piece of aerospace aluminum and then machined to maximum lightness, narrow pin bosses and the ability to handle the power demands of a 1600 horsepower engine. We are able to maintain the same piston weight as a forged piston but handle the abuse of endurance or drag.

These pistons will be available in many different configurations from stock bore to 100mm with compressions ranging from 9.0 to 10.5:1, the pistons will also be available for your 4.3 liter stroker kit for those looking to set some records. When your GTR requires nothing but the best, choose the Gruppe-S/JE Billet FSR piston.

This is the official HPI Romania company car featuring the Gruppe-S GTR Drift car. I wonder what the Romanians think when they see this trucking rolling around?

There are even a couple of custom Hankook GTR R35s around, would love to see them if anyone had the time to do it.

HPI thanks for all the love over the years, Andrew Hilman and Rodney Wills we salute you.

The guys at JE Pistons have lost their mind

Posted by Gruppe S On Monday, November 15, 2010 0 comments
Our sales staff have kept this a secret for quite some time, but it is time to let the cat out of the bag. The guys at JE pistons have created a new FSR forging for the popular import applications and we are letting all our followers know.

The have been replacing all their Subaru applications and EVO applications with their new FSR forgings.

The pistons are extremely durable and lightweight, we have tested them to 700hp with great reliability. The best part is that these guys spend a lot of money developing this forging and they kept the price the same as the old pistons. Don't let these guys know, but we are stealing them right from under their noses. Pick up a set before they find out and start raising prices.

JE part #291061 8.5:1 stock bore 99.5mm
JE part #291062 8.5:1 .5mm overbore 100mm

Datalog using LogWorks on your PC

Serial IN and OUT ports allows for easy connection with other Innovate MTS and other devices

How the Numbers are Calculated if you are curious!

The calculation involves 2 Steps.

1 a) Calculate first how many revolutions of the crankshaft there are per second instead of per minute.
8000 revolutions/min x 1 min/60 sec.
= 133 revolutions / sec.

1 b) Then using rev/sec, calculate how long it takes to complete 1 crankshaft revolution @8000 rpm?
Using straight ratios:
133 revolutions / sec. = 1 revolution / ? sec.
? seconds = 1 rev. / 133 rev/sec.
= 0.0075 sec.
= 7.5 millisec.

Bottom line is 180milliseconds faster digital air fuel gauge means 24 engine revolutions faster at 8000rpm
