[QUOTE="olaosunt, post: 15212257, member: 131643"] Sorry for not updating this thread(I have on the other site) Here is a review and driving impressions (I don't have pictures on my computer and unable to load from photbucket anymore } So, we had some decent weather today(low 50's) and I had a chance to drive the On3 car. I am not sure how much is due to the better weight distribution of the turbo's(and I am sure less weight) making the Hellion car nose heavy or the Steeda IRS suspension parts(linear springs,IRS sub frame brace and bushing support system, vertical links-did not install PP rear toe links or bushing differential),one piece drive shaft,DSS axles, but the On3 car drives and handles like a dream. The on3 car was lighter to start of being a base, manual while the Hellion car is a premium auto. The car is a lot more responsive at part throttle .I don't know how much boost it is making since the cars OEM gauge (I know it is inaccurate from the Hellion car) is not reading anything . Under WOT the dump tubes are noisy and make an awful racket(like an exhaust leak which I guess it is) so I plan to route them in to the exhaust. Off course it does not pull like the Hellion car@WOT which is making about 14 psi and always has 100 octane in it (just had it on the dyno and it made 750/723 with MS109). The IMRC light is back on and the car surges/splutters a bit when I think I think it is starting to make boost at WOT I had the same issue with Hellion car with same p2007/2206 codes and it did not make ANY boost until my installer fixed it by rerouting the vacuum lines. I am hoping he can do the same with this car but I am waiting on a couple of couplers I need to install the induction system(I have all the tubes)routing air from the filters behind the grill to the turbo's. Right now there is just a screen on the turbo's so I am being real careful. If he can't fix it the same way, then I will be swapping the intake for one from an 11-14(Chad had one clearance already and I can swap with the one from my 12)or a boss intake. I just ordered a fuel system from Sai(he made me a heck of a deal) to run E85 with ID1000's.He will be retuning for that anyway so if I do need to swap intakes that will be a great time to do it. Chad had said it made 610 rwhp as it is on the dyno with journal bearing turbo's and it now has the BB. I can't wait to see how it drives once the IMRC is sorted out (one way or the other) with E85 and more boost. [/QUOTE]
