For how I use the car at this time, yes. I need the power band to be a bit more to the left. The turbo is awesome if I wanted to push for 600whp+ but those are not my goals. I will be more than happy to break 500whp with 475wtq around 4,200-4,500 RPM. Right now, I am looking at a stock IX turbo just to get the car on the road again and upgrade later. I do not like driving my minivan around town alone.

 

with a BB FP Red and even black you should see 400wtq before or right about at 4000rpms on your 2.4.

you dont want to go too small, the 2.4 eats up a lot of air and youll just end up with something that gets choked out in the top end and power drops because it doesnt flow enough air to keep up with the 2.4's powerful lungs

 

I just bought a stock IX turbo to see what the "fun" factor will be for the short term. I am very excited.

 

I guess I will just have to experience this firsthand as I just bought the turbo.

 

I had 400wtq at around 4200 when I ran the JB black on a fully built 2.3 stroker with CNC head. Not sure how much sooner the BB black would spool up... This was on pump gas at around 28.5psi peak boost.

 

Can someone please tell me what the issue is with getting the Perrin intake? Is it a great modification? I presently have an AEM filter set up on speed density.

 

ive hit 33psi by 3700-3800rpm on my fp black and 2.3 in both journal and ball bearing configuration in 3rd gear. this was on e85.

if you watch a video and i start around 2800rpm the needle kicks at 3500ish rpm.. very very responsive setup.

levars setup with a stock turbo will still be a lot of fun.. the stock 9 turbo is just big enough to have fun with the 2.4

for the most part though, the main difference between journal and ball bearing is the response / recovery time. it did spool sooner but not by a whole lot.. i have all kinds of data on my computer when i was doing testing in regards to that.

it is noticeable though just cruising around town.. the recovery time / transient response is a lot quicker on ball bearing.. the main key factor though is the durability of jb vs bb.. bb is so much stronger and will withstand a lot of abuse.

 

the perrin foam filter? i use it on my car.. not sure if its restrictive or not.. when its new and oiled up its not based on the testing done on here with it, but when it gets older / dirtier and loses its oil? who knows.. id run a big mouth K&N probably or the biggest filter you can fit in there on your sd intake.

 

This is what has me scratching my head about the EF4 (spool). I realize that it is larger than the FP Black, but I would assume that with the extra 0.1L engine size, that it would still be on par with what you saw, Tom. I was well past the 4,000 RPM mark at just 29PSI (or so) of boost. Am I the only one to see this issue?

For the turbo selection, please check your email as I am tinkering again. The stock IX turbo is on its way to my house but I am already thinking about selling it and buy a brand new ported BBK Full or ported 73HTA Green.

I will have Archie find the biggest joker around Tucson before I pick the car up.

 

i found the ef4 to spool similar to a t3 hx40 setup when compared. the fp black just spools quicker.. not much more to say really. you cant compare a black to a ef4. they are just to different... and thats a good thing.. because we want a variety of options in the community.

here is a cut of a graph of mine from 2010 showing spool with a journal bearing fp black.. this is with a mbc turned all the way down on wastegate preloaded.. the car hit 31psi.. just giving you an example of how quick a black can hit on a 2.3



you never loaded your car up from 2000ish rpm either and gave the turbo time to spool..
when you start later in the rpm range its gonna always hit peak tq later as well.. so yours
will spool alittle sooner then the graphs represent of course.

also keep in mind.. cams, intake manifold, and exhaust manifold all play a critical roll in spool and early response.. that above graph was with all OEM parts with port work. minus the cams.. the cams were kelford 272.

 

Yes, that FP Black/2.3L combination looks great. OK. So the EF4 did not have time to "warm up" per se as I was starting the pulls right at 3,000 RPM, correct? I was only doing what my tuner directed.

Yes, the more options for the EVO community, the better in my opinion.

 

Heck, I might just get the FP Black with the smaller wastegate actuator (since I have that terrible 91-octane here) by looking at this graph.

Since yours spools up like that and I am looking for something a tad smaller, maybe I should throw that FP Red (and similar) turbos into the equation.

Oh the drama...!

 

This was my spoolup on the JB black with MBC set at 28.5lbs (25lb actuator preload) and on pump gas. This was on a 2.3 with ported stock intake/exhaust manifolds and kelford 272 - very similar to your setup but looks like yours spooled up a little bit sooner...

 

With the 2.4L, I would just skip the red and go straight to the black. On the highway in 5th gear (shep ultimate ratio), the response was almost instant even with the JB black. Unless you need the powerband to kick in sooner...

 

Wanguru, this is not a FP Black comparison thread. Before I know it, there will be others throwing in their FP Black "spool" results and that is not what I am after. Do not take that the wrong way. I am just trying to keep things on topic.

I am trying to decide what turbo to go with aside from the EF4 as its lag was too much for me.
