yep steve done my 33 ... real impressed the man got 380 bhp@ 0.8-1.0 on standerd injectors , with the owens turbo unit .....she spinns up real well !
basicly the mans a hero ! soon to be tweeking my 32 !!!! watch this space !
My astra has just been mapped by steve...and if i'm not mistaken it was his first vauxhall.
The head went a while ago runnig 2bar on stock 1 piece vaux turbo so with no previous mechanical or eloectrical knowledge I started to strip and rebuild my engine. I added an s14 tubular "ram" exhaust manifold, cutting and welding to a vauxhall head flange. I then mated this up with a GT28RS turbo and with custom intake pipes and exhaust the car was ready to be tuned.
I took it to a well known company and the figures seemed really good. 360 bhp and 373ft/lb. I have a good friendship with Bobby B (uncle Bob) and had the car booked in at Hayes Engineering (Erith) before I had even had my map just to make sure everything was safe. Turned out the fuelling was terrible!!!!!!
Anyway...I asked steve what I would need and after attempting to run haltech interceptor decided with Omex 600. Once again...attempted this and I got it all running (and I still dont know how to use a multimeter properly!! haha)
I trailered the car to Hayes Engineering as although it would start and idle, the Cosworth 3 bar bap sensor and other components I had to change were not working together.
(Had to do away with electric FBW throttle for cable one, OE map sensor went, and standard coil was replaced for wasted spark setup (EDIS setup) with magnecor leads.
Steve plugged into the omex sat morning (6th march) and instantly got the car to idle properly. Drove it onto DynoTech rollers and started the tune. 1.5 hours later (after a boost pipe popping off twice the fuelling map, and ignition map were set up. We then started upping the boost and found out that the actuator that came with the turbo was shagged (after trying to run 1.8 bar constantly).
The figures were still pretty impressive and the drive is so smooth (although it just spins!!)
Made 260bhp and about 300ft/lb @ 0.4 bar.
Just ordered a HKS adjustable actuator which i will set to 1.1Bar to hopefully hold 1.3 - 1.4 bar!! Cant wait for more torque. =D
I would not trust my car with ANYONE else now after being to so all of the "top" tuners for my manufacturer.
Steve...I cant thank you enough for all the patience you have shown me during my project. Especially with the Haltech interceptor.
Steve...I'll see you as soon as I get my new actuator, and Bob...probably pop down this weekend!!
If you have not already been "FC TUNED"...what are you waiting for!!
