It has been a decade since the DE came out and the platform has seen its fair share of FI kits flooding the market ranging from some not so great ones to some plain and simple awesome ones. However with turbos giving out generous portions of power it has hogged all of the attentions leaving the supercharged options starvingly skinny and realistically only down to the Vortech. Nothing wrong with the Vortech and it has demonstrated to be tried and true option with great results, but where is the excitement and what if i want chocolate and not vanilla?

GTM has been hard at work on the VHR and has released a vast array of upgrades for it that have gained great popularity. One in particular is their latest rotrex based supercharger kits. If you haven't seen it yet, go to their site and check it out right here (VHR STG1) and here (VHR STG2). Not too shabby right? But sadly, that's for the VHR and we are DE (minus those few HR guys). Luckily enough, that will no longer be the case and a similar kit is currently being fitted on a DE and yours truly my DE

The project started a few months ago and should be done fairly soon. From a high level view, these are the parts that will go in my car on top of my well modified built 4.15L 11CR block, more info can be found here (11:1 VQ42DE).

A little comparison I did between this kit and the vortech. link to pros/cons

As a side note, I know there are some of you guys that have their differences with GTM but this thread is not about that so please keep those to yourself.

 

how's the progress Gabe?

 

It's going well, hopefully be done very very soon How's your car with the SC?

 

About time Gabe. I know you were talking about it! Congrats on pulling the trigger. Can wait to see results!

 

It's not doing bad other than a few oil leaks here and there. Sam just sent me new oil lines so I can fix those on my next oil change. Other than that I should get my car retuned as its still eating lots of fuel.

 

That's good to hear, who are you gonna take it to for the tune?

 

Thanks, me too How's your car doing?

 

I'm waiting anxiously

 

In a nut shell we are taking every thing we have learned over the years from all the other kit on the markets including ours and coming back with the ultimate Sc kit for the DE platform .

This kit will have the best power potential, the best belt wrap and tensioner system out the of gate .


Here is a pic showing the difference in size between the HKS unit and ours.



Stay tuned for more

Sam

 

so this super charger is being fitted to gabes setup which is a fully built stroked engine. will this supercharger setup work fine on a stock de motor??

I know everything will bolt up the same but will a smaller supercharger be fitted?

 

We will offer 3 different stages for the platform, stage one will be designed around stock engine safe power level .

So your are covered

Sam

Nice!! Will the STG 1 price be comparable to the other SC kits on the market?
