Robert is an awesome dude. Iv got his 8892 on my 6.0 and havn't had any complaints. Your radio show episode with him is one of my favorites. He always gives out great information.
It would probably help customer education for Robert to post the inducer/exducer specs on the website so people can resolve any misconception with how he names his turbos.
PR of 2:1 on both compressors is 4:1! 45 psi. The power of multiplication. UHF turbine wheels are the real deal, the one on my 62mm Xona Rotor turbine has done very well compared to standard type turbine wheels.
I thought that too but I think a twin-screw would prevent the air from going in the way you want it too because the screws only allow a certain amount anyways so it would kind of make the turbo are hard to tune or almost unnecessary to make more boost that's why I can't wait to see how it goes because there's just not enough info
@@freedomfox8183 but it would be fed condensed air. It would work the same as compound turbo. It just would have positive displacement down low and even more tq production in low to medium rpm. But maybe too much tq. lol
@@4familymanCheck out Norris Design.His blower will disengage and bypass once the turbo is spooled up.Probably fun for I street car or super big power, but for me the new turbo tech spool fast enough.
How does this s400 stack against a gt55 base? I have one of your budget s480 going on 2 yrs and a drag and drive. It’s done very well. I’m really considering this new turbo being a drop in replacement. Thanks
I got a 98 Chevy truck I'm putting lq4 with 799 heads e85 sloppy best cam Holley cpu wanna do 600 to 800 whp what turbo should I use. this is a junkyard build low budget need a cheap turbo
It will make a lot more than 1000whp. You could go a bit smaller and have more response if the goal is 1000whp. His Hd8082 would be a good choice. Or even better a Xona 10569s
@@chipcurrey653 boost threshold also matters for a street driven car. An s480 on a 4.0l will of course make 1000whp but also be a turd. The HD8082 is only $850 from FP and would be better suited. Yes the Xona is $2k but it’s next level of spool and performance. Even the little 68mm 9569s would make 1000whp.
@@4familyman where is there any dyno testing on this? Richard holdener has the 75mm compressor version of that 8082 in videos (the 7582) and the turbine side does not look 1000 crank HP capable, or maybe just barely in his super ideal conditions. I had the fp 8082 on an lq4 6.0 with the ss2 on my last Buick and now I have a $288 eBay s475 on an ly6 6.0 with the sloppy best cam in my new Buick. It makes more power per pound of boost and both spooled before converter stall speed. It isn't apples to apples due to the better heads but I am interested in any testing that shows the standard t6 hot sides on the s400 series are turds in real world conditions.
