Naoto who does all of M2Ks Motec work is one of the best in the industry, glad to finally see someone step up with the motec. We have an adapter harness and an M130 for this same goal, we may focus our efforts on the C6, and let M2k handle the heavy lifting on this one. We would gladly buy parts from them if they were for sale.

Got the tank dropped today and got the Fore Innovations triple pump setup installed. Also found out the Motec should bypass the requirement to use the prime button....so that's one less thing we should have to worry about. Motec should handle that from the key-on position similar to the factory system. Hoping to be on the dyno later this month, so hopefully the updates will come in a bit quicker moving forward.
Sweet build!!
Leaving the bottom end stock or are there plans to address that down the road?
Love this build to see some of the limits of the LT4 and A8 pushed!! Good luck!!
Stock bottom end for now. Once we get it all sorted, I will build a new block for the car so it will be ready once the time comes. I am sure it's just a matter of time, but who knows...some of these guys seemed to survive a long time on the stock bottom end. Skip Harmon's car ran great for 20k+ miles.
Some progress pics...getting closer to firing it up. Motec is complete, Fore fuel system is complete (just needs electrical wiring wrapped up), intake is complete, catch can is complete (just needs hoses made and routed from valve covers and dry sump). Should be running this week, then we will have Naoto fly in and have Pat G come up and start on the tuning work.
Once everything proves out, we will get all the metal work sent out for powder and paint to pretty it up a bit.

I will give you a guess # on the rwhp with the set up & that cam spec 1120 to 1140. You are going to love the F1X in the car man.. Robert
That's pretty much the target on the current iteration of the build. Once the motor is built and a more ideal cam is spec'd, it'll go cog driven and be turned up....but for now, I would like to make around ~800whp on wastegate and 1100-1200whp on high boost. So if we hit 1120-1140whp, it will be mission accomplished for this go around. But we should find out here pretty soon.

With a good cam & really good set of heads that blower will make over that 1200 more like 1300 plus with the correct set up..But again you will love it the way it come in and just keeps on pulling.
On my c5 RHS 427 with 245 heads from that I got BTR to do for me with a very small cam made for the street it did 1173 RWHP on a mustang dyno thur a RPM level x trans and only a 3200 stall.
Plus I didn't know before I started the block build the RHS block had a bad place in them on cracking if you pushed much more than 25 lbs of boost so I only did 23lb and didn't go no smaller on the pulley.
Let us know what she does man & let me know what you think of the blower. I am just not going to go all out and crazy in this c7 so will keep it as a little TI head unit with a 3.6 pulley & meth.

Got the car fired up last night for the first time to make sure we had no leaks or issues....time to start buttoning it all back up so it looks like a car again. So far so good, almost time to make some noise.

Great to hear what has been done so far is good & moving onto the end of getting it to the track.
Going to start working on some off-boost drivability tuning tomorrow and we have Naoto form NCS flying in next weekend and Pat G coming up so we can hopefully get started on making some pulls assuming everything goes well this week with just regular driving, data-logging, and remote tuning to get the basics buttoned up.

Pat G will do a great job for sure. Great at remote tuning heard nothing but good on this from guys that get him to do this. But I agree on a job like this would want him in the car & also at the rollers with WOT also.
Cant wait to see what this does on the WOT & even more at the track. Good luck guys on the car.. Robert

Initial tuning is done, got the car making some steam, but ran out of pulley around ~22psi (256 kpa). Now that everything has been tested out and working like it should, we are going to be removing some engine parts for paint/powder around Labor Day and I will get a smaller pulley installed to be able to turn it up a bit more. Very happy to make 4 digit power with zero meth, just pump E85 (E78 is what we got). For some 100 degree August Houston weather, it came out great. On the wastegate we made 850whp and we made 1000+ around 22psi on M2K's Mustang Dyno.
The cam is definitely not the right cam for the car, but the plan is to start a motor build this winter and the new engine will be designed for this setup, so the heads, cam, etc... will be much more optimized compared to what I am currently running. Wannagofast 1/2 mile in November will be a good test to see where we are at in the real world opposed to the dyno sheet guesstimates. So I get 2 weeks to drive it around some and get some real world testing done to ensure we are 100% satisfied with the engine manners, drivability, boost by speed, flex fuel, etc... but the Motec integration with the GM EMS so far has been excellent. Naoto from NCS has everything working like it should, including having the Motec trigger the low-side pump to prime the high side pump on the Fore In-tank setup....so no need for a prime button to worry about before you start your car. All-in-all, very happy at the moment with the power, so it's time to get out on the street and track and see how the performance does.
Did a similiar build F1x car with a 4" upper and IW 9% lower and we see 22.5lbs at 5700 rpm and belt starts slipping and we are down to 200kpa by redline...
Still on the 8 rib from procharger and to be honest I hate Procharger's tensioner and trying to talk the owner into doing a true spring loaded tensioner...
Owner taking to the track tomorrow night and hoping for 120+ in 1/8 and 150+ in 1/4

Sounds like some strong numbers in the c7. Ben post slip on the f1x track time..

Its a bad dude!! Should easily do 25+ pounds with no slip... that was in 93/meth too... (3 14gph nozzles), plans to running c16 in conjunction with that tomorrow!!
Car is a manual and the owner can drive... the DA should be pretty solid tomorrow night
I will have to re-look at the logs to review the kpa near towards the top of the powerband. So far, no dusting or typical belt slip signs being identified. I know AMP has a 10-rib setup out and M2K had done a Cog drive on their last F1X C7, so there are some options if we experience issues.
The 18% IW Pulley says it's a 9.5" pulley, but also states it at 8.75" OD. So I'm not sure which figure I should be using to calculate the blower RPM.

Factory z06 pulley is roughly 8.1 so
8.1x1.18=9.5
This car wouldn't knownit was slipping if it wasn't from log.. still hauls ***...
10rib with a solid tensioner will get the job done IMO
