lookforjoe Posted October 22, 2014 Author Report Share Posted October 22, 2014 Time to try some LS2 coils. I had fantastic results with them. Or LS7's Do you guys have specific PN's for these? Or do I just do a general search for LS2/7? Do they use three wire like the Bosch? Do they need a heat sink rail? Truck Coils?? Each coil does two cylinders?

D585 are supposed to be the best. http://www.ebay.com/itm/GM-Gen-3-5-3-6-0-Lq4-Lq9-Lsx-D585-Ignition-Coils-/251676345925?pt=Motors_Car_Truck_Parts_Accessories&hash=item3a99144645&vxp=mtr 1000whp GTO at our shop is running them, upgraded from the LS2 coils I am running.

That's what the truck coil is listed as - that is one per cylinder? >Found Trents' setup Justus - what did you do for dwell times/tables?

VulvaS40T4 Posted October 22, 2014 Report Share Posted October 22, 2014 (edited) Those stock T5 coils from bosch are tested to be good for 250hp per coil so i dont think that coil is the problem and this is with e85 ethanol fuel which is much harder to ignite. Check also your cam timing. How much is intake and exhaust cam open in TDC in millimeters thanks?

Cams are set per Enem recommendation: 1.2mm EXH 1.5mm INT Set on True TDC on #3 not by Volvo markers Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted October 22, 2014 Author Report Share Posted October 22, 2014 In between the thunder showers I replaced the BMS coil packs with the OEM Volvo packs I had bought & run for around 10k prior to installing the BMS coils. So, new DPP+ fine wire plugs @.026", and now the coil packs. With this, the breakup/stutter and idle are all gone. I would need to reinstall the BMS coils one at a time to determine where the fault lies. Not sure I care to bother . I think I'll get a set if the D 585's & build an alternate coil array. With TunerPro, I can adjust the dwell maps ( with help) . I just need to get the onboard COP working in place of the add on TT COP I'm using now. Going to order a new air filter & make a new can to fit - I can get away with the 9.5" tapered cone I listed in Simply Volvo's thread RU-5045 flows 1127cfm, VS 1186 of the one VulvaS40T5 is using, which I would have trouble fitting as it is 7x9 cylinder, VS cone (6.75x9.5 w/5.875 base OD) >Reference post Also need to fit this & make new DP to match the WG offset >Original LGSpeed Header Install Thread And maybe I'll fit my crank scrapers/windage kit while it's down Quote Link to comment Share on other sites More sharing options...

lookforjoe Posted October 22, 2014 Author Report Share Posted October 22, 2014 Looks like a stainless LG maifold? Indeed. I already have the mild steel version, don't ever buy one, it will rust out at the collector within three years. Quote Link to comment Share on other sites More sharing options...

lookforjoe Posted October 22, 2014 Author Report Share Posted October 22, 2014 I'm going external on a 20g and I was thinking about grabbing a lg manifold I did use the current LG header with my 20g hybrid. Just bite the bullet & go SS. Quote Link to comment Share on other sites More sharing options...
Modman Posted October 23, 2014 Report Share Posted October 23, 2014 I know viva sells the kind you got but not the ss one. I'm assuming I'll have to contact him directly correct? Quote Link to comment Share on other sites More sharing options...
