Alex Posted January 22, 2003 Share Posted January 22, 2003 If your Fuel Pressure Regulator works fine then don't waste the money...In my opinion. I'd put the cash towards a better mod. Having said that, some have fitted them with no problems. Though one that I know of has failed. Quote Link to comment Share on other sites More sharing options...
Errol Posted January 22, 2003 Author Share Posted January 22, 2003 Thanks Alex...Can you recommend Sanspeed in Bexleyheath ?? Quote Link to comment Share on other sites More sharing options...
Alex Posted January 22, 2003 Share Posted January 22, 2003 No, I can't. Cause I don't know who they are...never heard of them. Another member might though... Quote Link to comment Share on other sites More sharing options...
terawua Posted January 23, 2003 Share Posted January 23, 2003 My muvva lives in Barnehurst, so I have heard of Sanspeed I think a lot of the local renault 5 (etc) posse can be seen aournd there. Personally having just upgraded from a fiesta 1.8 diesel I didnt really have occasion to go there.... before now. I owuldbe surprised if they have seen more than one or two supras in their time.. maybe worth a call to Chris Wilson? plus you get to drive on the M40 where there arent many cops Quote Link to comment Share on other sites More sharing options...

I'd put the cash towards a better mod. Agreed. We've never used them here. Theres no reason too. We only change to the adjustable HKS one when we fit the HKS fuel rails as the OE one doesn't fit. They can be beneficial on some cars (mainly NA stuff) but the MK4 isn't one of them IMO. Cheers, Nathan TDI PLC Quote Link to comment Share on other sites More sharing options...
Myles Posted January 24, 2003 Share Posted January 24, 2003 I used Sanspeed a few times with my last car (corolla), but I did the work myself & just used them for the rollers as they're local to me & quite cheap (about £35 for a `power run' IIRC) . Let us know what you decide & how you get on . Myles Quote Link to comment Share on other sites More sharing options...

Ian C Posted January 24, 2003 Share Posted January 24, 2003 To be marginally more useful, Chris puts all his contact and location details at the bottom of his posts, so just do a search for posts by Chris Wilson and you'll be inundated with info. -Ian Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted January 27, 2003 Share Posted January 27, 2003 This isn't to say FSE's don't have there place. Normal FPR rise at 1:1, from memory the FSE rise at something like 1:1.7, or something like that ( please chip in if this is wrong). Basically meaning you injectors will flow more because of the increased fuel pressure. Handy on J spec injectors. Don't really like them much though.

Tolly Posted January 28, 2003 Share Posted January 28, 2003 Hi Guys, Long time reader, first time post! :o) I've been researching the 'Power Boost Valve' for my N/A, and I found the following information. (You can also purchase this product from Fensport) Firstly, this valve has an adjustable fuel pressure, effected by the movement of an adjustment screw on the crown of the unit. New Power Boost Valves are pre-set with a maximum fuel pressure of 2.5, 3.0 or 3.5 bar, depending on the vehicle in question, and similarly (to the original valve) the fuel pressure is reduced by 0.5 bar approximately at idle. There the similarities end. On acceleration from standstill the Power Boost Valve fuel pressure will increase at 1.7 times the standard rate. This will produce a healthy, strong fuel mixture strength which will instantly improve the drivability of your vehicle, providing:- instant throttle response removal of performance flat spots faster acceleration extra engine performance The regulator enhances engine performance on acceleration by enriching the mixture strength. On constant throttle and cruise conditions the valve returns to a normal regulator function. The Power Boost Valve is simple to install and in most instances basic fitting instructions are provided. These units are mechanical and are considered maintenance free Quote Link to comment Share on other sites More sharing options...

Adam W Posted January 28, 2003 Share Posted January 28, 2003 Just because it pumps more fuel into your engine doesn't mean that you'll make more power or that the car will feel better. Running rich may not damage your engine but it can feel really treacly and sluggish. IMHO I would steer clear unless you have strong grounds to suspect you car is running lean - your ECU is a thousand pound bit of kit which has been rigorously mapped by toyota to provide proper fuel mixture under all conditions, assuming that the stock regulator is in place. If you try and fudge the issue with an FSE thingy, you're effectively taking mixture control away from your expensive ECU and handing it to a crude mechanical device. If you want to squeeze more fuel out of your stock injectors you would do better getting a 1:1 rising rate adjustable regulator and increasing the base pressure by five psi or so to give you some more headroom, then use a fuel computer to fine tune. Or just do it the proper way and buy bigger injectors! Quote Link to comment Share on other sites More sharing options...
