If performance is nearly identical, then doesn't it make sense to keep the Toxic-Fab, since as you say, "construction quality is second to none"? That way you're more likely to enjoy that performance with theoretically greater product longevity.....right?

Did you mean " doesn't make sense NOT to keep the toxicfab?

Again, great info by mrfred!

Nope. I meant it the way I wrote it. I was asking him if it also made sense to him to keep the toxicfab unit, since it's got higher build quality. Either way you slice it, my vote is for him to keep the toxicfab unit, and sell the Fid unit, based on his review.

Very cool post post, with good information. I have the FID Battery Tray and the construction is excellent, especially after looking at other people's setup's at the FLA Annual Evo meet.

Best thing about both these products is lifetime warranty. This post will help in my decision when Iam ready to upgrade manifolds!!

Hi MRfred, thanks for some great information! Looking at the dyno plots, how much of the power/torque loss below 3700 rpm would you attribute to the exhaust manifolds and/or the BBK Full compared to your stock exhaust manifold with Evo 9 turbo baseline, also does it matter much that the baseline run seems to start 200 rpm later?

I ask because I am planning on switching from my stock ported Evo V RS turbo to maybe the BBK Full next year, and since I autox a lot, its something to consider. I read in other posts though that the Evo 9 turbo spools much faster than en Evo 5/6 RS 10.5 turbo, so maybe with the BBK Full I might not even loose any spool.

Thanks,

Ricardo

I wish I could answer that question accurately. I did the HKS cams, BBK Full, and tubular manifold all at the same time. I think very little is lost with the HKS cams, so I suppose the later spool time can be split 50:50 between the BBK and the tubular manifolds.

The thing is that the way the turbo spools when starting out side its efficiency range (e.g., starting at 2300 rpm) may be much different than how it does inside its efficiency range (e.g. 4500 rpm). If I had thought about it more, I would have done some transient response measurements starting at 4500 rpm with my old set up and these new setups.

What I can say is that when going WOT, I haven't noticed any difference between my BBK setup and my Evo 9 setup.

Interesting to see how people interpret my post. Both are well made enough to last a lifetime. Another thing to consider is that the ToxicFab uses non-304 stainless steel flanges.

Thanks for the great review! its clear that both these manifolds are excellent quality and really well made, making pretty much the same numbers.
I wonder if proper sized port entries (like the shearer fab manifold) would yeald any better numbers, my guess is prob not much. I say as competitively priced that these two manifolds are i would rather get one of them.

Nice write-up!

any chance of throwing a ported stocker on your car to note the differences while running the same bbk?

Yeah, I'm interested in this as well. Perhaps in a couple months after I take care of some ROM stuff.
