[John@Lethal]

We've put up some teasers within the last couple days, but here's the thread where we will post up the official pricing, links, and other information you guys may have. Pricing and availability will be released by today or tomorrow. These kits will also be made for the 05-06 Ford GT Supercar's as well. We'll just update these threads.

First, here's the first look of the Lethal Performance's 2013 GT500 custom painted 4.5L supercharger. We're super excited to finally get our hands on this beast after being as patient as we could.

[IcebourgGT500]

I'm assuming elbow is the limiting factory on our application?
Looking forward to seeing comparison vs. the 4.0L.
At what point do you think its worth the upgrade over the 4.0?

Curious about fitment. Will the same mods needed to make the 4.0L fit work on this? Do you have any comparison pics with some of the other blowers?

As far as we know so far, same mods (adjustable motor mounts, k member spacers, ect) will be required to clear the stock hood.

We don't have it in our hands yet, so no comparison pics just yet, but we'll try to get some when the transfer takes place. Thanks!

Good god ole' mighty! :rockon: Once I get those new Manley H-Beams installed next fall, my little white 2.9 might get bumped for a 4.5!

4 second dyno run!

That escalated quickly...

Was that time laspe Photograhy or did the dyno let loose and free wheel?

Yikes, that thing is ripping.

Just letting you guys know we installed one of these on our 2013 GT500 (Snow White) and the results were very impressive to say the least.

There's an article in 5.0 Mustang & Super Fords magazine coming out shortly which gives a direct comparison between the results we got with the 4.0L and 4.5L. The 4.5L in short made almost 150rwhp more than the 4.0L at the same boost level. The TQ gaines were even more impressive.

So if you're looking to build a monster the 4.5L is definitely the way to go.

We'll be back at the drag strip with our car soon and will be sure to post track results then.

Let us know if you have any other questions.

Thanks, Jared

Do want!

Is the clearance needed to fit this the same as with the 4.0L?

The 4.5 requires the same mods to fit under the stock hood as the 3.4l and 4.0l. That would be the k-member lowering kit with lowered motor mounts.

Let me know if you have any other questions.

Thanks,
Jared
