Vaughany Posted October 5, 2003 Share Posted October 5, 2003 I am looking to purchase a Boost Controller for my J-Spec TT. Is there a particular make/model that is recommended and do I require anyother eqpt to run the Bosst Controller safely on my car. Just out of interest what boost can I run safely on the car before I need to purchase safety mods etc. My current mods are as follows. Blitz Nurspec R Exhaust 2nd Cat removed HKS SPF Induction kit In Increasing my boost what gains in BHP can I expect and just out of interest, what boost will I approximately be running at the moment. Cheers Quote Link to comment Share on other sites More sharing options...
THOR Racing Posted October 6, 2003 Share Posted October 6, 2003 Vaughany, I notived no one replied so.... I would recommend an Apexi Boost controller and running a max of 1.2 bar (maybe turned down to 1.0bar in hot sunny weather) You'll need a fuel cut defencer as well. Change of spark plug temp grade plus removal of 1st catalytic converter as well. You'll be looking at a quick car then. Later a front mounted intercooler to help cooling. If you need any help contact me direct on 02476 362144 I'm only in Coventry. Regards Pete Quote Link to comment Share on other sites More sharing options...
TLicense Posted October 6, 2003 Share Posted October 6, 2003 Pete, Is there any particular reason you would recommend the apexi over a Blitz DSCB id? I'm also looking to get a boost controller and the Blitz unit was recommended, but is there any functions the Apexi has over the Blitz? Many thanks, Quote Link to comment Share on other sites More sharing options...
Vaughany Posted October 7, 2003 Author Share Posted October 7, 2003 Pete thanks for the advice, a couple of questions though. * Taking into account my existimg mods, what level of boost would I be running at the moment. Also could you clarify the following. I noticed sometimes boost is measured in bar and other times PSI. what is the difference and is there one. * A fuel Cut Defenser, I have heard that these are bad as they only disguise the detonation and dont stop it. By having one of these on you are stopping the ecu from doing its job and risk blowing up the engine. Is this true? I have recently had my plugs replaced with TRUST Racing plug No 8, are these anygood and do they meet the required spec you mentioned. Man thanks Vaughany Quote Link to comment Share on other sites More sharing options...

Man thanks Vaughany Hey Guy - poor old Peter is a working bloke - how long you got? Bets to check out some of the past threads on Levels of Boost FCD (pete's is the best and HIGHLY required! Spark Plugs There are loads to look at! IMHO I like the Blitz SBC-ID for it's looks - not sure about what it does over the Apexi however:thumbs: Quote Link to comment Share on other sites More sharing options...
SkyJawa Posted October 7, 2003 Share Posted October 7, 2003 I'm interested to see this too. I'll be in the market for a boost controller (when funds recover after shelling out on new tyres to replace the crap it was supplied with!), and Pauls got me pretty tempted with the Blitz Would be good to know if theres any reasons to go with different makes like Apexi AVCR, HKS EVC, Greddy etc....

Guest Terry S Posted October 7, 2003 Share Posted October 7, 2003 IME the Blitz Dual Solenoid controllers hold boost better than others. Quote Link to comment Share on other sites More sharing options...

SkyJawa Posted October 7, 2003 Share Posted October 7, 2003 Mine is decat Restrictor is too small though so I need to enlarge it, though in the summer it will drop the boost again, hence the boost controller! Quote Link to comment Share on other sites More sharing options...

Thats the problem I've got at the moment. Had the restrictor ring put in an April and it held fine at 1.1bar, but now I've got a new intercooler and its dropped in temperature I'm getting 1.3bar. Dont want to hold it at that for too long. Quote Link to comment Share on other sites More sharing options...
Willson Posted October 7, 2003 Share Posted October 7, 2003 [J-SPEC] I got one (lower) cat out and a manual boost controller set to max 1.2 bar at a little over freezing. Automatically reduces boost to a little over 1 bar on a hot day. Buy Pete's FCD (TRL VFCC)...http://www.thor-racing.com/TRL/products_boostcut.html Bar and PSI are just different units. 14.5 psi = 1bar (ish).

Steve W2 Posted October 8, 2003 Share Posted October 8, 2003 14.7 psi = 1 Bar to be exact:) How does your manual boost controller automatically reduce the boost pressure? The Apexi and Blitz don't even do that. have you got a clever temperature sensing system that you have done yourself? Quote Link to comment Share on other sites More sharing options...
Willson Posted October 8, 2003 Share Posted October 8, 2003 Yeah super clever thats me, honest. No it's just a bleed valve ! As I understand it, the difference between electronic and manual is that the electronics adjust a solenoid to COMPENSATE for changes in air temperature (in turn oxygen density, in turn boost made) and load etc.......... Probably b*llcks but it makes sense to me Quote Link to comment Share on other sites More sharing options...
Steve W2 Posted October 8, 2003 Share Posted October 8, 2003 I hear ya! So how does you manual contoller adjust for the changes in air temp/density? If it does that by itself I think I will get one as opposed to an electronic type. I thought they were just a Knob that you twisted to get more or less boost. It obviously manually adjusts the solenoid to give your more or less pressure. Do you think it's worth getting a electronic type? Quote Link to comment Share on other sites More sharing options...
Supragal Posted October 8, 2003 Share Posted October 8, 2003 Actually, glad this came up- bit off topic but mine has a boost controller- all it says on it is 'blitz tuning system dual sbc' any ideas as to which one this could be?? Or even how to use it?? When I push buttons it goes red which is a bit scary!! Quote Link to comment Share on other sites More sharing options...

Willson Posted October 8, 2003 Share Posted October 8, 2003 A completely stock car will make more boost on a cold day. Manual boost controllers like mine are fixed to a position that you choose, but the outcome will still vary with the air temp. Like I say electronics compensate for this, by bleeding more or less air, to hold a SET boost level. I would still get an electronic if I had the money.

Yes it has a 37 number code along the length, each number is about 1/2" wide when in use. Joking aside, what does the controller look like? It sound like a normal DSBC which really isn't a bad thing.

What you were actually saying is that the ambient conditions effect what bboost your car runs:) Yeah, thats what I thought! Quote Link to comment Share on other sites More sharing options...
