A must have for all 7.3 owners
Let me just say that this turbo was more than what i expected. Amazing performance and sound ! Lower egt ,more power and quicker spool up.
Clay has been nothing but helpful with my questions A 1 Customer service -
38r w billet wheel
This is what a 7.3 should have been from factory, I had a great custom ( stock) turbo that worked very well for towing and daily driving, when I put this turbo on, it completely changed the I felt about keeping it stock. It spools like lightening and tows like it is on steroids. If you own a 7.3 and don't have one then you are missing out on what your truck can actually do. Just wish I got one sooner

Best drop in upgrade by far
I am absolutely impressed. Spool up time is great, sounds very very nice. RiffRaff had the turbo at my door in around 3 days. EGT's are down by ~100-150 degrees. Definately a nice upgrade from the stock turbo.
Pushin about 7-10lb boost cruising with no load at 55-60mph. Seeing around 20-25 lb boost WOT in combination with the tunes I have.
One of the best purchases I have made for my truck for sure. -
sounds great
Great upgrade not as loud as I thought it would be but you can still hear the spool up :) you can definitely tell there is more air flow seeing it out performs my stock turbo with a ww. And not needing as much boost. I also installed a billet wheel before I installed much lighter then the stock wheel that comes with the turbo

I spent countless hours reviewing Turbo upgrade parts and kits, I figured the heck with it,I bought the 38r..Plus Riffraff has 'em on sale…What an awesome upgrade…Thanks Clay!!

For the money, great replacement for my old turbo
It's an excellent stock turbo replacement. I had some trouble fitting the intake boot to the turbocharger, but it went in after a little finagling. I'm bone stock other than this turbo and a T500 hpop. I didn't notice any increase in fuel economy, nor any power increase, but again I'm bone stock. I replaced my old turbo just because it had 200k on it. I feel so far this turbo works perfectly as a stock replacement. With mods, I'm sure it would outperform the stock turbo, but it works exactly as it should as a plug and play, long lasting stock replacement.
