Slow FD gets the win!

[Steve_FD]

its 100db for a public track day and 108db for racing.

[lee mills]

Cool. Aiming to get there for a few track days next year just got to shave a few db,s off first:Thumbsup!

I was there was good to watch.... The Radical of Andrew Shanley was phenomenal i timed a 1.03 and i do believe it lapped most cars in the GT race. It was frikin cold up there as well

a rotary powered radical? has it been done?

[bimbleuk]

Our little Radical Clubsport was only 1300cc but using a mildly tweaked Hyabusa. We managed to get down to 1:05s by the last season we entered. Not bad for a car built on a £15K budget
 
I would really like to try a sequential box in one of my cars soon. Unfortunately I was too large to fit in the Clubsport with a foam filled seat made for my very slight neighbour.

Great to see a rotary winning

[marky]

I can make you one that is quieter than that and still makes the power.

What size system and what size box\'s are you using? Waste ate plumbed in??

Cheers

How much does a stock FD pump flow at what voltage? What pressure are you running through the injectors?

Seems like bosch might go out of business if the stock pump is capable of running 600bhp worth of flow (hp+safety margin for the race car)?? Tell me more!!

[Brett]

Am I being blind/stupid again? Can\'t see the power figure?

Presume you had a custom loom for that? (Out of interest, what sort of amperes are you pulling on the pump?)

[Grant Monkhouse]

You do realise that Carl originally said "up too 600hp" not dead on 600? And he\'s talking fwhp.

The thing is Carl isn\'t going to tell you how he does it as it is business and has tried many things. Have you ever been to see Carl and talked too him at his shop?

If the FD ignition system is good for up to 600HP then why can\'t any of the other Mazda products installed on the car be capable of the same thing?

Hmm interesting few points you raise there.

First off - I only presumed that the HP for the car above was 500hp - a number I plucked out of the air, to which i added a safety margin of fuel flow to equal 600hp.
If you are saying that its capable of 600hp, I would then add 100hp of fuel flow as a margin as no one would run a pump at 100% - just like you wouldnt do with injectors - agree?

Second, if there is some voodoo majic trickery going on to make a stock fuel pump deliver huge amounts more power, then its pushing the boundaries to call it stock or make a fuss of the fact its stock - kinda like a hi flow turbo, or drilling an injector pintle - both of which are possible and done by people, but for most its fast easier to obtain a higher rated unit thats also new for simplicity and peace of mind. I would take \'stock\' to mean that whats in there does the job with no biggering around, end of - unless I missed something of course. Which is the case?

Third, there are more things on an FD would stand up to much less than 600hp so this too kinda makes that point irrelevant too - intercooler/clutch/injectors/exhaust/ECU etc.. Also - I thought most people chasing that kinda power would upgrade the ignition with a twin power or CDI system. Does this car also run stock ignition?

[Grant Monkhouse]

Somehow I don\'t think that you just plucked the 600HP figure out of the air. I know full well where you got that figure from and so do you.

I have no idea what Carl does to the pumps, I\'m not interested in finding out tbh. If he says they work then they probably do.

I really don\'t understand you intentions for digging up this thread? Are you genuinely interested to maybe try these things out yourself or are you trying to have a dig at Carl?

Why so defensive fella? I have no idea what you are on about - I plucked 500hp out of the air as my post states - ("hp+safety margin for the race car"). I thought it fairly rational to assume that a 20% margin was about the right figure to arrive at 600hp worth of fuel flow, but not supporting 600hp - they to me are different things. You  added \'up to 600hp\' (which btw is 600hp in my book - but I digress) to which I added my 20% (or 100hp in round figures cos my maths is bad) to get 700, because I know its bad practice to run anything at 100%

I purchased a Bosch 044 for my wheels as I wasn\'t aware that the stock FD pump could match that - I am genuinely interested in this if its the case as I could have saved myself a few bucks. So far as \'digging up a thread\', well what really attracted me to this thread was the fact it seemed to be some new revelation based on the huge \'look at me\' typeface in the first post - are you implying I shouldn\'t ask or be interested in this particular fact?

I think given the jumpiness around here I\'ll leave it alone and stick with the 044 - you are answering the question but don\'t know the answer and tbh don\'t seem that confident in it either as judged by the \'Probably\' in your response.

Cheers anyways dude.

Good job. Beautiful black beast. I was amazed how neutral and "easy" to drive that car seems to be...

Ok, my apologies then.

This car has recently made 450rwhp on low boost of 1.3bar iirc, car has been mapped too more than that but knocked down for longevity as it gets used in anger a lot, and doesn\'t need that much power. All on the stock pump.

[HaywardRotary]

That 450rwhp was on about 1 bar boost Grant. it usually runs around 1.3 bar to 1.4 bar.
