supercharged88

Hi everyone, haven't been on here for a long time. I had a double brain stroke 2 years ago, still recovering. I have setup a new business also, it is called Pro Tuning and my website is www.protuningcairns.com I will be dropping back in from time to time again. Hope everyone is good. Regards Dave.

Hi all, has anyone tried any adaptors or apps for like NOKIA WINDOWS 8 PHONE. I have an iPHONE with KIWI WIFI and REV which works great but I also have a cheap back up phone which is a NOKIA LUMINA WINDOWS 8 phone. Regards Dave.

Hi everyone, I was wondering if anyone knows of any apps such as REV and TORQUE but to suit a Windows 8 phone. I had a browse last night but could only find junk. Any suggestions please. Regards Dave.

Hi, I haven't ever tried to tune anything with SCT or VCM, but have experience with standalone ECU'S. There is a method that can be employed to achieve a lumpy type idle without camshafts or the ECU/SOFTWARE not having Cyclic Idle Control. I have used it years ago on ECU's with DBW control but no Cyclic Idle control to give the effect of big cams/ ghost cams. It lays within the idle speed control (DBW) and idle ignition timing values. It is a matter of inducing hunt in the idle by using a low timing value at idle and a higher timing value at idle at the closest cell to the idle timing site. With tuning the PID's of the DBW and using the timing value methods you can create your own ghost cam effect. The trade off however with speed density is the drop in manifold vacuum at the lower timing value and the point that the idle speed drops, creates a rich idle mixture. This can be minimised with time needed to fine tune this setup. However it also tends to replicate the high hydro carbon, burn your eyes out idle type effect of big overlap camshafts. EG: 106 deg lobe sep and 300 @ 0.050 if not setup properly. I notice a lot of Commodores at idle seem to have been tuned with this manner also. Workshops fit camshafts and the engine doesn't produce the lumpy idle the owner is seeking. The tuner then employs similar tactics I have mentioned above to produce a more lumpy idle. The give away to this is the fast hunting idle lope, instead of the consistant idle lope. I know of a workshop that does exactly this after I mentioned to him how I used to do it in the earlier days. It still sounds ok, but not as good as a true big duration, tight lobe separation camshaft, which by the way goes against the grain of true boosted engine camshafts. Tight lobe separation and big duration sounds good, but you have heaps of valve overlap, you end up pushing boost out the exhaust. Good ECU's coupled with good tuners tame camshafts down, compared to an engine with the same grind camshaft and carby, the EFI engine will always idle smoother and sound tamer. Sorry guys just a bit of dribble I thought I would pass on. Regards Dave.

Large diesel engine can be run on dynos, that are specifically designed for diesel engines. Horsepower calculation is a product of torque. Large diesel engines may only rev to 500 or 600 rpm flat out, but produce massive amounts of torque. However I would think that the ocean going freighters and passenger liners engine horsepower would be a calculated figure, much like the Top Fuel Engine. The other issue with the top fuel engine is the rpm they spin them at, 8000 -9000 rpm. Most engines produce linear/progressive type power, however Top Fuel and Top Alcohol engines both produce explosive instant and progressive power/torque. The dyno's simply physically cant handle this type of punishment. Regards Dave.

Hi, from memory they made gains everywhere and a overall peak power gain of around 100 hp (I think). So yes tuning in the VVT definitely improves the engines output. I am pretty sure that they left the base tune alone and only tuned the VVT to make these gains. Regards Dave.

Hi, Installing an ECU such as the i88 is time consuming. I have fitted V88 to both BA XR6T and BA XR8 with a Harrop supercharger.. Both cars still run the DBW which is controlled by the ViPEC directly, no extra DBW Modules or interfaces required. These cars took around 4 days each to complete, installation and tuning. I have not done a Coyote so I don't know how long this would take. You need to search for a ViPEC dealer, installer near you. Regards Dave.

Hi, 5252 Motorsports have done ViPEC V88 installs to the Coyote engines, with full VVT control on inlet and exhaust camshafts. The Ghost Cams that they refer to in the above videos, is actually better known as CYCLIC IDLE, ( controlled cylinder misfiring basically). This is a feature that ViPEC has had for many years. If you go to YOU TUBE and search ViPEC CYCLIC IDLE there are plenty of clips of cyclic idle being used, you can make a complete stock engine sound like it has large duration tight lobe centre line camshafts fitted to it. If you go to the ViPEC website and click on the NEWS section, there used to be a story by 5252, I think it was titled " Who said VVT was for emissions only" or something like that. It is the story about the Coyote install. The new I SERIES ViPEC has fully configurable CANBUS control for making factory dashes etc work, also has OBD2 protocol so it can be used with iPHONES, iPADS and ANDROID devices with REV or TORQUE apps etc . Regards Dave.

I agree with everything you have said turbo, I had dealt with Spiro on a fairly regular basis. He was very passionate and a true gentleman. I have been recovering from a double stroke myself over the last 3 and a half months. I am lucky to be alive and have full function of my body. Unfortunately death or major health problems cant be avoided. My advice from this is to enjoy life. Enjoy your family, loved ones and your friends. You just never know what's around the corner. It would be great to see Spiro's machine continue down the path that was chosen for it by a great man. (SPIRO). Regards Dave. P.S sorry for the thread hi jack.

I think you might have to join Photobucket to view. Regards Dave.

Hi, I used to do a few ST185 GT4's quite a few years back. They are great little engines, the stock turbo and manifold/cat design where a bad point however. Very common for the wastegate seats to crack. If running the stock ECU you will hit factory boost cut at anything over 10 psi from memory. The check engine light will come on, you will then need to switch the ignition off and restart the car for the boost cut to reset. If you have a look on my photobucket account, there is a ST185 GT4 I built a 3SGTE for, custom intake plenum, stainless headers,GT35R,front mount cooler, full forged engine. My Photobucket account is supercharged88 Regards Dave.

Thanks for the replies. Yeah John, we have ordered a new 6BOOST twin gate manifold and received the new Precision PT7675 turbo and twin gates from SPIRO today. Just waiting for the 6BOOST manifold now, keen as. Thanks unclewal, I think that was the engine. Regards Dave.

Hi all, a few months ago, I thought I saw a picture on this forum of an XR6T engine bay with a large turbo and twin external gate setup. The dual wastegates were sitting up top of the manifold behind the turbo from memory. Can anybody direct me to such a photo, I am curious what brand of manifold it was. Thanks Regards Dave.
