lots of interest in the new blouch 1.0, 2.0 and 3.0. I dont need to see any of these new turbos as I know better than anybody the wheels designs he uses and how he operates his business selling turbos. the new turbos ARE cbrd turbos renamed.

the pics here are of switch I made several months ago. was running fp red and switched to a dominator 2XT. the dom 2 uses same wheel sizes as bbx-b . on left is BBK-B on right is FP RED. the compressor is indeed quite a bit bigger on the blouch turbo. and the turbine quite a bit smaller.




I have mixed feelings of the two. my swap included both turbos having a non ported shroud. here is the readers digest on the but dyno on my 2.3

bbkb spools up much faster. at least in 1st, 2nd and 3rd. the surprise is in 4th and 5th the red makes way more tq at low rpms. like 40+tq at 3500 rm. and pulls harder to redline. the bbkb is far noisier. there is just far more air noise and it bounces the BOV far more. driving around town the BBKB is far more responsive in 1st through 3rd. but sometimes too responsive. a bit hard to regulate where the red is far more linear with throttle input. I seriously miss the quietness of the red and the tq 4th and 5th had. WOT the red feels much faster in 4th and 5th. in 1st through 3rd the BBKB feels just a tad faster. I think on a 2.0 the clear winner would be the BBKB. but for me in my setup i miss the red and wish to reinstall. problem is the red was BB and it messed with the maf counts basically giving false counts at throttle lift. just killed drivability. so my next move is speed density with switch to the infinty ecu. then I can put the red back on.

another interesting note is the BBKB is JB and the red BB yet the you could not tell from driving them. one might guess that the BBKB was ball bearing and the red PB from how they drive, before installing I compared the rotation mass of each by rolling the turbine shaft in my fingers and the BBKB is far easier to spin. the turbine and compressor wheel are made far lighter than the red components. I would estimate the red turbine weighs 200 grams and the compressor 80 grams. the bbk compressor 65 grams and the turbine 150. its a very stark difference between the two. my guess is driving around a track there woulld be no difference between the BBKB and BBKB BB.

these pics are of bouch 1.0 (oldcbrdbbk) next to billet 20g. the blouch wheel substantially bigger yet 50grams and the 20g 61grams. amazing strong but light alloy.


sigh

 

great info. i recall you mentioning before that the red produced better power in higher gears. still trying to understand why.

 

Review the price difference

 

Google it.


Nice review!

 

Yeah +1 I read the same thing in the prior and it didn't make sense to me then and still doesnt...what is used to control boost? Could it just be that the red prefers higher boost pressure such that the additional load in 4th and 5th gives it the upper hand? It would be interesting to see the boost curves of the two as that may pain the picture. Nonetheless, great info thanks for sharing

 

I am still leaning towards the Dom 2.0 instead of the 1.0 even though I am on stock block and won't be pushing the car too hard. Thank you for the information.

Holy crap, you have a lot of turbos! I will keep an eye out for your For Sale thread when you switch back to the Red lol

 

Interesting. I would think it has to do with the load. I would think the higher load makes it take longer for the turbo to get to max shaft speed thus building power for a longer time whereas the 3B being lighter reaches max shaft speed quicker and being more linear giving the effect of less power.
Does this make sense to anyone else?
I would like to see a compressor map comparison of the 2.

I can offer up a VD graph of my car in 4 gear before the new owner picks it up. CBRD used 3 gear for tuning.

 

so, i do some auto-x for fun but mostly HPDE and GTA/RTA events. i'm in CA and run Buttonwillow, SOW, Big Willow, Sonoma, etc.

i was going to go with the 1.0XTR... but now i'm thinking i may be happier with the 2.0XTR? i'm running a mild cam (Greddy 264) on a built bottom end. i see the 1.0 flows less than even the FP 71HTA (which was my first choice before the Blouches came out).

opinions, please?

 

The Red is nicely configured having a relatively lower backpressure turbine side compared to the 3-B. It is the same turbine wheel used on FP's larger Black turbo.

I had a JB Red and then switched to a BB 3-B. I agree with 94AWD about the Red having better power delivery and response in 3rd-5th. I think that it is related to the lower backpressure, higher inertia turbine wheel of the Red.

 

A Bizzaro BB turbo configured with the 3-B's compressor wheel mated to the Red/Black's turbine wheel might be nice. 94AWD has all the bits sitting there on the shelf and would just have to have it dynamically balanced.

 

I would say go with the 2.0xtr. IMO the 1.0xtr is not going to flow much better than a stock 9 turbo, so why bother.

 

That's what I'm wondering. The 71HTA was as small as I was willing to go. I don't want to run out of steam at 6k RPM. Now, if my choices were 1.0XTR or 2.0XT...I'd have to do more thinking.

 

A Bizzaro BB turbo configured with the 3-B's compressor wheel mated to the Red/Black's turbine wheel would be nice. 94AWD has all the bits sitting there on the shelf and would just have to have it dynamically balanced.

 

If the 1.0XTR is the BBK Full, then its much better than a stock 9 turbo. There are multiple examples of the BBK Full making 485-500 whp on E85.

 

I don't remember the BBKF flowing less lb/min than an FP 71HTA. Or a green, for that matter. Was it smaller?
