Soon to be new owner! Michael Roark Superlite SLC Build

Hey Guys,

I stumbled upon this forum late last year and just now got around to signing up. I purchased a Superlite SLC w/ a Graziano transmission in late December 2020 from RCR. I'm still waiting for it, but hope to see it soon. We are 44 weeks since the date I ordered, but who is counting! So far, I've purchased a LT1, Turbochargers, BOV, Wastegates, Holley Terminator and a few other bits. I look forward to documenting my build with you guys and sharing my experience.

Build Specs -

Model: SL-C
Drive: LHD
Color: Grabber Blue
Rear End: Race Tail
Wheels: CF5V 19x9.5 Front and 20x12 Rear
Extras: Fiberglass extended door cards, interior tub, a-pillar covers, and parking brake upgrade.
Engine: Twin Turbo LT1
Engine Management: Holley Terminator
Transmission: Graziano w/ Billet Shifter

Changes I wish I would have made

Tinted Lexan over clear.

Michael,

Congrats on the car! Should be a pretty potent combo.
Are you planning to use the Graziano L140 as-is with a turbo LT1? What sort of power
are you planning?

Welcome to GT40s.com Michael! I would think that RCR could make the exchange in Lexan for you at this time. Give Fran a call...
 
Congratulations Michael. Now would be a good time to send the graziano to Ron McCall for a drop gear upgrade.

I left a message for the RCR service department to see if I could possibly get the transmission shipped out earlier. Do you have a good contact number/website for Ron? We had Dallas Performance build our last Graziano transmission, but that was a full gear set. I'm going to do some research on the drop gear upgrade today.

Thanks for the heads up!

Michael

I'm going to start out with making around 600-800hp and then look at upgrading the transmission. We made around 1000whp on our Gallardo with the factory transmission for a few months before we upgraded to a fully built transmission from Dallas Performance.

Michael,

My # is 410-596-3170 and my email is [email protected]. Give me a call some time tomorrow or shoot me an email if you'd like to discuss having some upgrades to your trans.
Thanks,
Ron McCall
 
Out of curiosity, what are the transaxles going for with the pre-installed gear upgrades?

Sorry for the late reply. I have been completely slammed at work. I will look tomorrow and let you know the upgrade cost. I'm still waiting on the email to say my car is ready to ship. Should be any day now! I'm super excited.
