Larger displacement needs larger AR. It’s all relevant to a combination of turbine wheel, engine size and displacement. Larger turbine wheel doesn’t always mean you need the same AR. Bigger turbine often a smaller AR with the same peak or slightly more exhaust flow works. I only lost 150 rpm switching to larger AR on my last turbo so it wasn’t a loss. Less boost but more ignition timing. Made up way more of the difference.
discharge delta across turbine blade is massively important relative to drive pressure required by compressor which is also effected by ar and inducer exducer ratio, blade count pitch eyc
That is a mine blower 500 hp but like you said if you’re not on it by the 60 foot you’re going a little backwards as usual I love simple math. Thanks for the update!! What day are you headed to the track?
this is very interesting could I ask what engine size? T6? do you know N/A hp? just saying we changed AR it worked on this engine doesn't mean it will work on everything
Did your egt climb with the smaller ar? I’m about to reduce from a 1.15 too a 1.0. I could go as small as .84. But kinda worried me. I’ve got a 7.3 powerstroke.
@@jakoblongnecker9385 stock 90cc. AA injector.. but. I found out if I get a later set of intensifier and only use the piston with my AA sleeve they will be AA single shot 160cc. So I may be doing that as well. Or building myself a set of hybrids.
@@hondaxl250k0 I don’t mess with 7.3s much but I would go down to a 1.0 housing. An .84 will spooo quicker but the 1.0 will give you alittle more room for added power. The .84 may get hot on the top end when you start adding fuel

Crazy! Thanks for sharing. I’d have never guessed you wouldn’t give anything up on the top end with the smaller housing.
I freaking love your videos and tech explinations. Appreciate all you do for the platform

Well said man good luck on the bigger turbo housing.😊
💯 Look forward to seeing it run at the track
Well damn. Very well said.
That gain is absurd also! WOW!
Great comparison
Great video Thanks for sharing the data
Nice big differences and definitely help me out I was going with twin turbos. Either FORCED INDUCTION turbo OR FORCED PERFORMNCE Turbo
I've since switched to Garrett G series and would not change. G series is the shit.
@@aedtuning8441 Nice Right on Garrets out of budget tho lbvs 🥴😂
@@aedtuning8441what had you been using before the G series?
THANK YOU !
Thanks Shaun! What is the comp ratio on the engine? Good luck with G50, looking forward to the results.
Great info!
I have a 12.7 litter Detroit diesel. I need a quick spooling, long-lasting quality turbo. Help?

Next weekend is a grudge race down south

How much fuel are you throwing at it? You will probably see a drop in egt and your power will be a lot more useable

@@jakoblongnecker9385 well I ordered both.. figured not hard to change. I’ll play around and I’ll have all 3 if I need to change.
I'm about to put twins on my car and I'm afraid I'm going to have spooling trouble. I couldn't get any advice on what turbos to pick
Contact Jose at Forced Inductions
What did it pick up with new turbo? At the track..
Blew thru the converter.
so far it's 8mph faster at the 1/8th
That's why they have compressor maps! No pays any attention too . That will tell everything you need to know about turbos 😢
Compressor maps are for the “compressor” side.
Says nothing about the turbine side.
@@Venomm8314 you are not a winner 🏆. There's really that not many different turbine side differences.
What size engine?
