Gen V LT Direct Injection Horsepower Secret: Tech Tip Tuesday

We created our 72 Nova race car to develop and learn about Gen V LT1 LT4 L83 and L86 engines. And we did just that.

In this video Doug shares some valuable info on fuel systems as it relates to line connections and feeding the High Pressure Direct Injection Pump.

Fittings as seen in the video!

Keep the LT stuff coming. More people need education and tips for them. Thg thanks guys!

Thank you for looking out for us LT guys 👍. Excited to see what else you come up with.

Fun fact, when I was a process engineering intern I worked with this fuel line and there is actually a check valve inside the flex joint. GM wanted to prevent the high pressure pump from loosing fuel before starting. If I ever get an lt4 this will be the first thing I remove.

Great video, thank you. Your explanation was simple and straight forward. I'm doing a swap and was curious about how to convert from push-on fitting to AN. Perfect!!! I just bought 2 from your website.

I have a l86 and a 72 nova so I appreciate all your videos, keep them coming

Itd be pretty cool if you guys did more gen V tech tips. I don’t have one but I want to learn! I feel like you guys do a great job at explaining things so there easy to understand.

Sure wish I had seen this 5 years ago. Great advice guys.

Would like to see a video updating us on your Nova, after what happen on your way up race week. Never heard any details on what actually happened..

[MountainMcCumbee]

I wish this would be offered as a kit. I’m going to de doing a cam swap on my L83 and just ordering 1 kit would be great and not having to search different fittings. Have you guys thought about or tried anything on the injector side of the pump? There’s restrictions inside that tubing as well but with the high pressure maybe a bigger I.D. stainless solid line that could match diameter of the pre pump side hose and fittings.

[mrmchaffey]

I will be buying my fittings from you guys to help support your R&D thanks for all your efforts

[saudi]

can you show what the finished line looks like after you do this upgrade ?

[thehpw]

Love the gen 5 videos. Going to swap into my 68 Camaro

[bowlofduck]

Awesome video, I just subscribed. Would love to see more on beefing up an L83, both expensive and inexpensive options.

[aaronmindrup]

can you show what the finished line looks like after you do this upgrade ? pretty please

[ericmclaughlin]

Great tip! I am working on a gen V swap for my JK and was looking at using a stroker gen V but I can't seem to find torque numbers below like 3500 rpm. Not looking to build a dragster but would love to have stump pulling torque.

[paulpasternak]

Like the tip.
Lt to 91 c1500 planed.
Please more!

[anthonybomicino]

Do you offer a flex line replacement with the fittings for a direct swap on LT1/6th gen Camaro?

[RAWRMotorsports]

[rubenvor]

Great info! Thanks for sharing. Who does stand alone flashing for the PCM and TCM on these engines?
