Yep that's right I live in good old Blighty

Thanks for the recommendation to get in contact with Robert - he does seem to be the man to speak to about my queries.

Do you recall how the flow rate info was issued? Was it published on the FP's website? I'm wondering if the latest FP black has an increased flow rate or if it just has improved bearings.

Hi Conrad - good to see you on here buddy
Thanks for sharing your data with me - I know how you can be secret squirrel with your development work .
I think it's very unlikely that I'll want to convert the Black to run an external gate. I'm sure a 68lb/min flow will be more than adequate for me

35psi is what... just over 2.4bar - that sounds like a good healthy amount of boost

If the new core is indeed a lot more durable/reliable then this is probably a good figure to consider.

Without hooking a shaft speed sensor up it would be educated guesswork wouldn't it? I can well believe the the turbo will be working very hard and spinning pretty quick at over 9,000rpm though.

I will try and seek advice from Robert @ FP and see what his thoughts are.


That would tie in with the thinking of Conrad and Marios. Maybe the DCBB Black can take some more though.....

I don't have an EGT plumbed in at the minute but I don't think it would be too difficult to one hook up, read on my ECU and displayed on the dash. I will need to do some research but my initial thoughts are it sounds doable.

So you think running boost over 30PSI will likely cook the turbo it's subject to a road racing application? That's an interesting opinion, may I ask why you have that opinion?

RE - sump..... now that's a whole new thread right there and a real can of worms.
If I was running slicks, big aero and the car was an out and out race car then I would fit a proper dry sump kit. These large alloy sumps/baffled sumps only really help a little bit and by no means solve the problem. I am of the opinion that the only real solution to the problem is a dry sump kit. My car isn't an out an out race car - I can avoid full slicks and big aero and as such I will be running an OEM sump.
I will say that I am running a Kiggly HLA as I think it's a neat little product that's worth the $ - it will help.

E85 is available over here but unfortunately it's not easy to get hold of without ordering it by the drum. As such availability, storage and ability to refuel conveniently are the reasons why I don't and won't run it. If it was available up and down the country at many garages then I would love to run the stuff.
The car will be mapped and set up on Shell V-Power pump fuel - which has an octane rating of 99RON (our RON octane rating is different to your AKI and I thiiiiink 99RON is about the equivalent of 94AKI but don't quote me on that).

Running a meth mix, meth/water/LPG injection could be a way to lower the temps but that's something I may look into in the future.

Thank you - that's ueseful info . May I ask where you found this info or is it something FP shared with you?


I hope you are joking too. If you weren't - we were talking about turbo shaft speed dude. I would definitely not recommend trying to rev your motor to 147,000 rpm - if you do please video and post on here

I run 34 PSI of boost, tapering to 29 PSI by 8500 RPM's on my DBB FP Black using 93 OCT pump gas with no issues and EGT's well within an acceptable range. FWIW, I made 466 WHP.

I plan on upgrading to a 3-port boost controller and a custom MAP downpipe with an external dump and running 34+ PSI throughout the RPM range on pump. When I go back for a re-tune, I will also be doing an E85 tune at 40 PSI. I hope to make 500+ WHP on a pump retune, and 600+ on an E85 tune.

If you don't have an EGT gauge, definitely get one before you start road racing to keep an eye on the temps.

The new DBB FP Black, has been designed to accept much higher boost levels than advertised. You should be fine with 35+ boost.

You should also look into better oil such as AMSOIL. I run AMSOIL 20W-50 ARO with an AMS wet sump oil pan and a kiggly HLA. No issues to report. Life's been good

Thanks for your post Binky

I have a Perrin 3 port solenoid and my downpipe is a modular 3" one (Mongoose I think...)
Here's a few pics of it:



Right now I don't plan to run an external waste gated setup and I will be running the can on pump fuel - Shell V-Power (99 RON).

Oil - I'm not 100% but I think my tuner uses a synthetic oil by Millers. I will need to find out the exact details of the oil.

I would like to get EGT sensor set up and displayed on my Racetechnologies Dash2 if possible. A shaft speed sensor would be nice too - I will ask Robert about a custom compressor cover.

I sent Robert@FP a message about what boost to run on my setup... this was his reply:

Sounds good to me! I'm not sure my fuel system will handle that so I will have to see - I've a feeling an upgrade will be required but we will see how it fairs.

Good luck with your future mods - let us know how you get on!

Wow that is a lot of boost! I would have figured that prolonged usage at such high boost levels would cause excessive EGTs.

I wonder if that is what Robert was referring to. I guess as long as you have a gauge to monitor you are all good. Sounds like fun.
