Forced Induction's FI91X report!
Can't wait for the new power adder to come in. You all know me. It's hard for me to keep anything to myself. Once I start installing it, I'll post some pics and reports on the mondo upgrade.

It was busy at work today. I'll get the pictures up tomorrow. Promise. Actually, it looks just like the FI98X Scott posted recently. Advancement of fuel delivery? The inducer diameter on the compressor wheel is just a little smaller.

It is a monster. It's going to take two people to hang this sucker.

The nozzle area of the turbine housing is exactly what I was hoping for.

We'll make her fit.

For those using Performance Trends Engine Analyzer Pro v3.5, the turbine housing nozzle area for the 1.1 a/r gives a turbine nozzle diameter of 2.58". I was looking for 2.60". Shweeet!

, it will meet your needs, I can assure you that. That same turbo made 1481rwhp on a 2Jz Supra on boost ONLY..... So a GN should be able to crack 600rwhp.... ...lol

In all reality the unit spools very fast. The 94mm version of that turbo made t40rwhp more on a 4.8L inline 6 then a T101mm and spooled 1100rpms sooner. The unit has a low drag bearing system so it spins quite freely for being a larger unit.

Just some quick #'s so far: FI-91X on a 2JZ has done 1481rwhp. FI-94X on a built 1FZ which is a 4.5 but built to a (4.8) has done 1592rwhp so far. It could go more....but out of fuel and they are having a hard time keeping the head on the block. The 1FZ head casting is VERY long and thin, and tends to flex.

Correction: After studying the turbo I found that the a/r number that's cast into the turbine housing is 1.15.

I've been real busy readjusting my fuel map after switching to a larger fuel pump. I want to get that all squared away before I start flogging on the turbo install.

FI91X weight: 57.5 lbs. My tripod brace may start flexing with this one.

That should nail you down to 2.60 or so, or about what you had calculated. . If you can keep her between the walls....no real reason 7's shouldn't be done...

Yep. That's what it calculated out at using my crude measuring. 2.58. Perfect.

I'm thinking that with my present heads being the limiting factor, and if I can get enough traction from the new tires, I going to throw an educated guess out there and say 8.20s to 8.30s. If I could max out my chassis cert (8.50), that would make me proud.

Now if I had stage II heads, I'm with you JZ. 7s would be a breeze. You never know though. This engine has always surprised me in the past. Plus, there's always the option of spraying the whole run. Egads!

Just skip the 8's and go 7's. My thoughts exactly! The question is, at what point will the IC become a restriction?

The intercooler with the original plate and bar setup was good for 1500 cfm according to Spearco. It's got an extruded core now. Don't really know what the cfm max is on it. I need to look into that. Very good point Scott.

To match the comp wheel output you will need to be somewhere in the 2300-2400cfm range.
