Chris are your EF series turbochargers ball bearing?

 

I think the EF4 is too much of what I'm looking for. I don't want a mainly drag car so want low-mid end boost. If E-85 was close by, it would be easier to choose. Basically my dying BBK full is hitting peak boost (27 psi) by 3300 rpms and would like to get something somewhat close to that. 500+hp sounds good, but how would it perform stoplight-stoplight? I think I need to just get a ride in someones cars that has one of these to get a feel for it since I'm limited to only 93 octane.

 

This is intriguing. Could you go into a bit more detail on the compressor cover sizes, particularly, Chad! Pleeeze..

 

They are journal bearing at the moment until we can come up with a reliable solution for ball bearing. And yes the EF4 will reach full spool later than 3700, unfortunately it sounds like you're after the best of both worlds in regards to spool and power and as of right now you have to give up some of one to get the other...

 

Hey, I've just got the 2.3L running with the BBK Full. I'm not after big power, mainly quicker acceleration. And really don't want to change parts I've already upgraded.
Is it possible to convert the BBK Full Ported to a ball bearing?

 

I'm currently in the process of building my 2.3 liter. I have a bbk full with an 84mm anti-surge cover. I was thoroughly looking forward to seeing the results of high tq and quick spool. I'm curious if anybody can throw some results at me of 2.3+bbk full+pump gas?

 

Can't find original, but judging by the "dip" towards the end, I'd guesstimate that run I hit 450whp. 2.3 BBK full, and that was when it was like 30 degrees outside as well with two people in the car. My other runs were around 446 by myself. It spooled about as quick as my stocker did, but think now that I have the black, that was better for what I needed. I just think the BBK is a perfect turbo for stock 2.0. If you want torque, this packs a punch compared to the black, there's no comparison. On -my black I was at I *think* around 300lb-min at 4000 rpms. My Virtual Dyno is messing up so can't open my logs. Hope this helps, I'll post up my black to compare when I get home in the morning.

 

Is this on pump/93...? I like to see that the BBK Full seems to still be gaining power even at 7,500 RPM. This is pretty impressive to say the least, my friend. My fuel of choice is pump/100 though as I have a pump less than a mile from my house.

 

wow that power curve looks like alot of fun.

i have a Full and i eventually want to go to either a 2.3 or 2.4. i need to do some more research. im not looking for high horsepower just a fast street car, something i can run low 11's or high 10's easily and something i can take to a road course and it perform well. something that spools quick. my BBK Full has me spoiled im sure it wont be easy.

i have been contemplating a 2.4 with a BBK-B or C (depending on results) and just for the hell of it i would love to run a forward facing manifold with one of these turbos.

 

Thank you! That was exactly what I was looking for. My previous setup was a 2.0 with GSC S1 cam and a IX turbo with supporting boltons and put down 345hp/327tq, so I'm upgrading to a 2.3 stroker, BBK full and S2 cams. 450hp/450tq sounds like a lot of power.

 

Yes, that was 93 octane only. The head was only refreshed with springs/retainers but no porting. Speed density set-up

 

Wow. I can only imagine the power band with pump/100 and a 2.4LR engine. It looks like this could be a beast.

 

you can add BBK-C to the mix now, no?

 

not sure if its out yet

 

To me the thought of a B.B. Red is more appealing on a large dispacement mill than an HTA Green simply for the fact that the Red is configured with and shares the larger turbine wheel that FP employs on the Black. There is bound to be significantly less measurable back pressure through the Red's turbine than exists with the smaller major and minor diameters of the wheel used on the Green.

Likewise with the CBRD turbo range. Given a larger than stock displacement motor I would personally choose a 3B, or a BB-C over the smaller wheeled BBK-Full.
