Question: What's the most hp made on s400 frame turbo?

[MarkBroviak]

I believe it. Stock allison wont get power to the ground

Sorry but I call bs to this also! Unless you have a trany that's slipping the Allison puts the power down fine. The difference between engine and tire power is not that much even at higher power levels. I did a motor setup on the engine dyno then stuffed it in the truck then ran it on my chassis dyno. The difference was 12-14% hp and 22-24%torque. Issues with the chassis dyno is you can't load them down the same and that's why the torque difference is much higher. The issue with an Allison is getting them to change gears fast enough. This year will definitely be a great year for them.

A stock trans with that much power?

Go play mickey mouse games elsewhere. You're definitely on the wrong forum.

Think that was a joke^^^^ just based on his signature.

S400 frame record so far on my engine dyno is a StainlessDiesel S485/96 1.32ar at 1360hp. I'd also like to see them back that 1700hp single s400 at the track because I call bs too! To make 1700hp on my engine dyno as a single you better have a ProMod 91! Guess at some point I'll have to give an s488 a whirl and see what it does but I doubt it does anything close to that number! Three s400 will though for what it's worth!

I've been meaning to call and ask if you wanted to do a 88 vs. 85 shoot out...

They run out of efficient air at 600 don't they?

More like 500

650 hp's here with a diy 3 blade beer can turbo, conair hair dryer blower mod and a stock trans with saw dust.

Sorry

Lol sorry man. Didn't pay attention to your signature and thought you were serious.

You forgot a lift adds hp and the stickers of course...

So wonder how much the whirlpool sticker for my whirlpool heads, I stuck under the hoods worth??

It's all fine and dandy to make some fun...but I prefer to keep my mouth shut and simply let a guy to find out if it works or not...and THEN bag

Ben, thick skin goes a long ways...just know that most,, if not all of these guys probably have 10x the experience. Broviak builds turbos for a living and owns a dyno...he's not right about everything,but when he is he loves to rub it in people's face. Just ask Fleece Performance.

1747-14% is 1502. ....still nearly 250hp loss. Weight or resistance to movement will effect these figures a lot. The load on a chassis dyno can show huge difference in power loss, but most won't accept it because every dyno is different.

The more hp you make the more it looses. Acceleration takes hp. Now like I stated at the 1747 hp acceleration level it will consume more power before it gets to the wheels, Than a 1000hp acceleration rate will.

But that's my opinion. When one of you tries the turbo in question, tunes it and dyno's it. Then we can have a non speculation discussion.

Acceleration takes power??? Wow... Another brilliant bit of wisdom passed down from ngm motorsports....

Seriously, what would the industry do without you?

Anyone have any insight on getting good runs out of a large single? As far as driving and loading techniques? I dyno tuned a S480 single setup last week. Started the pull at 2200rpm in 5th gear and was able to get great consistent runs, even within 2hp & 3 lb-ft of each other. The problem is the charger would light so late in the run that the torque is not accurate because it was already past peak torque rpm. Basically​ is on the down swing of the torque curve by the time it lights. I wasn't worried about it at the time, just was looking for repeatability to tune. Horsepower was right on par with what it's capable of. I'm just wandering how to go about it. I didn't try to ride brakes or anything. Maybe start the run @ 1500 rpm and ease into it?

Should just jerk the motor and engine dyno it...
