So I have been running fb black (jb) for a while now. I like the power it makes (470hp on mustang at 30psi) but I Dont like how laggy it is.
I am spooling around 4k today and I would like to get into road course rather than hit high numbers.
I would like to stay around where i am today with HP (on pump) but I do not want to see the lag.
Is there a turbo you would recommend that would allow me to retain about 460 wheel but spool at faster rate?

FP Black BB would be the obvious choose but i would like to shave off around 1000 rpm if possible

I was looking at gtx30 w/ billet wheel setup. Is there any other tubros I should consider? I do not want to spend excessive amount of money on the setup either (3k+)
I also would like the set up to be direct bolt on as it would be convenient.

 

Maybe consider upgrading your black to BB, or jet a BB Red so you don't have to get different manifold o2 housing etc.

 

making 500whp on pump gas is a tall order in itself. to do that you need a large laggy turbo that doesnt create cylinder pressure at low rpm. so there really isnt going to be a smaller turbo that will spool faster but still make 500whp on pump gas.

 

The FP Red with the new SS turbine housing is very capable of such number, even without the SS housing I've seen Evos with FP Reds (stock block and strokers) that have come very close to 500whp or some have actually gone past it.

I don't know about safety factors and all that, but it is possible.

 

Well I do have a full built head and block. It's capable of way more than 500hp if needed. And like mentioned above. I also have seen people hit 500 wheel on FP red.

Now the fact that my black is jb leaves me the option of upgrading to bb or billet. Which could reduce turbo lag while keeping to end high.
This is why I mentioned gtx turbos above.
But I would like direct replacement if available.

 

The fp red is only going to gain a few hundred rpm in spool so is it really worth it?

 

The spool difference is close to 500 RPM as I have seen in some cases, and the Red will still give you that extra umph up top. I'd say it's still worth it.

 

So you are looking at going to a smaller turbo to make more power on pump gas? Good luck with that.

For what it's worth, the GTX3582R is bigger and laggier than an FP Black. You've given no engine specs or anything - my first thought would be go a stroker if you are on stock displacement.

 

i don't see how you could go to a smaller turbo than a black for spool, and still make more power. BB Blacks seem to spool faster (and for sure transient faster)

 

BBK-BB-B......you might give up a little power but spool and transient response will be better.

 

BB red and 35-40 psi. you will hit your numbers or pretty close to them.

 

BB green would give you the best spool and power for road course. You can make 500 on one on e85.

 

He wants pump gas... So 35-40 is impossible on pump gas. And obviously E85 is not 93.

 

sorry for the confusion. i do not need to make more power. i would like to retain where i am today but spool faster.
its a buschur built 2L block and head. Stroker is not an option at the moment unfortunately

Im only making it about 500 rpm faster though... i would like to see 1000rpm faster

im sorry but what is K and B? lol. Ball bearing black? ball bearing K??

Damn. Are people pushing BB red with pump at 35-40 psi?

Im thinking pump though.. red may be the better option at that point

thats what i was thinking...... maybe i just need to suck it up and go E85

 

Too bad there isn't any setup other than NOS to eliminate the lag under 4,000 rpm.
