supRo Posted March 19, 2005 Share Posted March 19, 2005 I've just come back from Thor. I had 2 X De-Cat (3"), Walbro pump, FSE Fuel regulator and Chrome dial kit. Previous mod on car: HKS cat-back exhaust, HKS mushroom induction, Blitz BOV, HKS Iridium plugs and boost gauge. Car was already reaching 1.0 boost, not too sure why - doesn't have an electric/manual boost controller. Dyno Result (Hub): At 1.0 Boost: 352 BHP : 126mph : 5856 r.p.m 339.5 ft/lb : 106mph : 4904 r.p.m Car feels bloody rapid especially when turbo 2 comes in . Also there seems to be an echo from the BOV, sounds like it's from the exhaust??? Going to have a boost controller fitted soon and run it on 1.2 bar. Toying with idea of a front intercooler and a polished/larger bore exhaust manifold, any opinions? Quote Link to comment Share on other sites More sharing options...
splurge Posted March 20, 2005 Share Posted March 20, 2005 Excellent work on the de-cat front. I had mine done t'other month and haven't looked back (mainly because by the time I turn my head round whatever it was I was going to look at will have vanished into the distance anyway). I've noticed: 1. It sounds much better. 2. It's got a bit more low-end power. 3. Exactly as you say, the second turbo now really, really kicks butt. Haven't noticed any BOV echo, then again I have a standard back box. Quote Link to comment Share on other sites More sharing options...
baldy Posted March 20, 2005 Share Posted March 20, 2005 re bov echo would it be wastegate chatter? Quote Link to comment Share on other sites More sharing options...
terribleturner Posted March 20, 2005 Share Posted March 20, 2005 Nice one Supro. I recently added the Fuel pump to my decatted engine and in made a huge difference. Was driving last night with my boost controller running 1.2 bar and it just felt fantasctic . I swear, every little thing that i do to the car just puts a bigger smile on my face while driving.

supRo Posted March 20, 2005 Author Share Posted March 20, 2005 Cheers guys, I think the BOV echo is probably the waste gate chatter - cos it is chattering now! Going down the M1 yesterday with a total of 4 people in the car and putting my foot down....Suddenly I see 155 mph on the Road Angel! I thought bloody hell, better slow down. Top end has increased drastically as before 140 took a little effort. The Walbro pump and FSE regulator combo gave a proven 18 BHP hike on Paul's (Miami GT) car using Thor's Dyno, so I had to get that done . Performance gain is amazing however it is a little too loud! I just have a silencer on the back box. Also the exhaust is hanging down a little and I now touch the humps but when I pop down to Thor next, I'll get that sorted out I'm also getting 2 different, occasional 'noises' at the back. One sounds like a stone hitting a panel (when driving normally) and the other sounds similar to central door locking mechanism opening when I turn the ignition off - Could that be the walbro cutting off?

Ian C Posted March 20, 2005 Share Posted March 20, 2005 the other sounds similar to central door locking mechanism opening when I turn the ignition off - Could that be the walbro cutting off? Could that be, I wonder, the seatbelt pretensioners? Try going for a drive, then cutting the ignition without taking your belt off first... -Ian Quote Link to comment Share on other sites More sharing options...
