supraturbochris Posted January 28, 2008 Share Posted January 28, 2008 Hello everyone. Just wanted to know. Since buying my supra tt beginning of the month, i have fitted the following performance mods. blitz nur spec r exhaust system. double d-cat from whifbitz blitz induction kit walboro fuel pump ngk iridium spark plugs Hks fuel cut defender. How much BHP do you think im producing at this point in time? Also this question is prob asked alot and people i know have different views but my supra is black. i was thinking a DO-LUCK front bumper, bomex sideskirts and either bomex or veilside rear spats blended into rear bumper or a trail rear bumper with TRD rear wing?? what do you think? cheers Quote Link to comment Share on other sites More sharing options...
jamesmark Posted January 28, 2008 Share Posted January 28, 2008 What boost are you running? Quote Link to comment Share on other sites More sharing options...
Lee P Posted January 28, 2008 Share Posted January 28, 2008 Depends on the boost your running, but probably around 350bhp. Do luck kits are very nice. Lee Quote Link to comment Share on other sites More sharing options...
supraturbochris Posted January 28, 2008 Author Share Posted January 28, 2008 standard boost i think. I bought her completely standard. Quote Link to comment Share on other sites More sharing options...

You will not be running standard boost if you have double decat, please do not say you have installed these items and not installed a boost guage.

supraturbochris Posted January 28, 2008 Author Share Posted January 28, 2008 na i havnt yet lack of funds after my giant spending spree. Next months mods. Boost gauges etc. Blitz or Hks front mount intercooler Greddy boost controller;) Quote Link to comment Share on other sites More sharing options...
tomgeer Posted January 28, 2008 Share Posted January 28, 2008 You will not be running standard boost if you have double decat, please do not say you have installed these items and not installed a boost guage. Get a boost gauge fitted quick mate you don't want to be overboosting Quote Link to comment Share on other sites More sharing options...
Mr. Fish Posted January 28, 2008 Share Posted January 28, 2008 you could be overboosting crazily mate....get a boost gauge asap...! Quote Link to comment Share on other sites More sharing options...
supraturbochris Posted January 28, 2008 Author Share Posted January 28, 2008 Ok ok i will scan on ebay now. It doesnt seem to over boost. it pulls nicely and not aggressive, found my mr2 turbo doing this when fitting the same perfornce parts but had a boost gauge.

Boost gauges etc. Blitz or Hks front mount intercooler Greddy boost controller;) You should have installed the boost guage first, when it is installed you will be able to tell how much boost you are running. If your running the desired 1.2 bar easily then there is not real point buying a boost controller as this only ups the boost it does not lower it.

supraturbochris Posted January 28, 2008 Author Share Posted January 28, 2008 quick question there is a hks boost gauge going on ebay cheap. Its an 80mm one, does anyone know the correct size of the circuler vent above sterio system? that would look well smart Quote Link to comment Share on other sites More sharing options...
Class One Posted January 28, 2008 Share Posted January 28, 2008 60mm, vents or 52mm for where the clock sits. Quote Link to comment Share on other sites More sharing options...
supraturbochris Posted January 28, 2008 Author Share Posted January 28, 2008 cheers mate, has anyone done this? easy to do? Quote Link to comment Share on other sites More sharing options...
Mr. Fish Posted January 28, 2008 Share Posted January 28, 2008 loads of people have done it mate also you sure the boost gauge you have seen is 80mm as you quoted Quote Link to comment Share on other sites More sharing options...
Wez Posted January 28, 2008 Share Posted January 28, 2008 I dont see a restrictor ring anywhere in that list, is your motor UK or jspec. Doesnt the HKS FCD just remove the fuel cut instead of raising it like some others, you should be very careful if so. Quote Link to comment Share on other sites More sharing options...
Mr. Fish Posted January 28, 2008 Share Posted January 28, 2008 Doesnt the HKS FCD just remove the fuel cut instead of raising it like some others, you should be very careful if so. I think they are adjustable so you can tell it to stop at a certain point... On some other cars, ive heard the HKS FCD's make it run stupidly lean...is this the same for supras or not?!

The FCD wont make it run lean, its the fact the boost is raised to such a point where there is no controlled fueling or not enough fuel. Supra stock MAP sensors run out at approx 1.25bar hence the safe max boost of 1.2bar, beyond this fueling is in the hands of the gods. UK motors use MAF and have different turbos, this is why some crazy folks claim 1.4bar is ok Quote Link to comment Share on other sites More sharing options...

UK motors use MAF and have different turbos, this is why some crazy folks claim 1.4bar is ok i thought the HKS Ones, basically fooled the ecu into thinking it was running less boost than it acutally is, hence why it doesnt hit fuel cut....and running lean, for example, say the FCD makes the car think its running 0.8 bar instead of 1.2bar, it will be fuelling for 0.8bar at 1.2bar, hence not enough fuel and it running lean....? Like i said tho, thats on a different car, so its different to a supe.. Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted January 28, 2008 Share Posted January 28, 2008 I dont think that bodywork combination would work at all Quote Link to comment Share on other sites More sharing options...
matt k Posted January 28, 2008 Share Posted January 28, 2008 It says on the Whifbitz website that a restrictor ring is £5, I would ask Paul if you bought one, and if you didn't i think it would be a wise investment. Quote Link to comment Share on other sites More sharing options...

That would be very bad as it would mean the whole map is off, this could also affect ignition as well, you could be running less fuel with more ignition for any given area of the map. Surely thats not right, if the HKS works like that I would bin it. What you want is an FCD that leaves the boost signal alone until it approaches the cutoff level, and then kicks in, holding the signal below the critical level. This is how the THOR FCD works.

Wez Posted January 29, 2008 Share Posted January 29, 2008 Just been reading up on the HKS FCD, it modifies the voltage across the whole range, the level of change is dependant on the setting used. Not good This is why its not recommended on http://www.mkiv.com in the tech area. Quote Link to comment Share on other sites More sharing options...
