Hondata 4bar sensor works with the GD3 flashpro and there is an option to use it here: https://www.hondata.com/help/flashpr...parameters.htm Once you switch the tic box from OEM to Hondata no other changes are needed for the change. I too would go to a single bigger unit over two 15-60's. Check into an after cooler and flex fuel setup for e85 and or methanol injection.

Make sure your injectors are good for E85, and add a really good sub micron fuel filter. I've found several cars at the track with what we call Alcohol salts in the injectors. the e85 cleans everything it runs through and carries it to the next filter or thing that the white crud can't fit though..

No plans on running e85. Not really available that much. I definately will be running the Hondata map sensor. No cutting and splicing if I can avoid it.

Methanol is more fun than E85,, nothing like 2' of blue flame out of the tail pipe.. But oh god the maintenance of the fuel system is a horror.

Klotz makes a product called Uplon (IIRC) I use it in sprint cars burning 100% Methanol, I highly recommend it in Meth injection its a lubricant and corrosion inhibitor that will protect all the metal bits in the intake. BTW inject DOWNSTREAM of the supercharger and don't run a bypass/recirculation valve open while the meth is on.. It will destroy most coatings in the superchargers eventually..

Just an impressed customer,, no other affiliation..

They have the engine out and apart waiting for them to send me some pics...


Head is being shipped today - 8-12 weeks turnaround. needs to be flow tested and re-engineered. They will create a program for the builder to run and cut the head to their specs.


Axles are being shipped today - going to the driveshaft shop for level 2.9 rebuild. 4-6 weeks turnaround.


They will be working on the block while the other stuff is out. CSS block treatment.


CP pistons are being shipped today. 74mm. 11:5 COMPRESSION!!! I almost fell off my chair. Don't know how they are going to pull that off but we shall see.


losing the a/c after all. Both blowers will hopefully put out at least 18psi.


Quaife LSD and Mfactory gears are on order.

And only 8.4psi of boost.

The 13.4 air/fuel ratios were scary looking. You know what you are doing though. Good luck!

The A/F readings were definately high. Makes me wonder how accurate my gauge is.

I never took it to the dyno. I was running the Hondata map and was adjusting the fuel from there until I figured out what to do with her.

correction on the boost level. They are expecting 12+ psi total but it will come on much stronger with 2 units.

Going to take a drive next weekend to check out their progress and take pics!

Ask them what your quench or squish measurement will be.

Why are they using a thicker head gasket rather then adjusting the piston to lower the compression?

Mother of.... When I had pretty much given up hope on this site LOL


Strapping in to follow along! I wish I had your budget, I'm putting together a MUCH simpler plan for a target of 220+ Wheel Torque...

Are these guys able to fabricate an adjustable cam gear, we NEED THIS!

And, if I understand, is your head being measured for future CNC work?!?!?

AND if they can setup a kit that mounts in the stock AC compressor location, I will SO buy a setup!!! Brackets and such are what I cannot easily, independently source or fabricate...

They wont know that until the pistons come in and the block is done.


EDIT: I cant share that info as he does not want it posted to the public. His secret sauce

LOL I AM SOOOO EXCITED!


No adjustable cam gear unfortunately. They will be replacing the cam chain as it has 50k on it. Looked fine to them but I want a new one. I am sure they could fabricate one if I had the extra time and money.

These them? JK Motorsports, Inc.

If they do in house CNC head work and are able to fabricate the cam gear... I may need a quote!

Epic stuff man. Glad to see some one else finally doing an L justice.

The CSS stuff... Where did you read up on the process, are you going through these guys? Cylinder Support System

Yes that is them


As for the CSS block...they do a similar procedure in house.

Sweeeet... Yea, I want to shift my power band, and to do that an adjustable cam gear and re grind is pretty much a necessity. Not a lot of serious places willing to touch the L, especially not ones as capable as these guys seem
