When I get knock, it's usually in a burst of typically 70 or 80. If something is rattling, i suppose the knock detector could count 200. Maybe it's not ignition. I've had similar knock at 60mph highway cruise when my F1 table was at about 30 degrees at 2000 in the 37 map column. My F1 is now...

Increasing the caster also improved the tracking significantly on my Ty. I think factory is 2 degrees, the "enhanced" spec. that I used for years was 3.5 degrees, but now I'm running at 7 degrees (by recommendation of another), and it improved both centering and tracking. Of course, first do...

Re: Back Seat I never saw the kit, but wasn't it just a couple bellville washers that added enough friction to the pivot that the seat didn't flop?

Re: JSM Track Day 2017 Re: JSM Track Day 2017 If at all possible, I'm in. I just can't predict my schedule that far in advance.

Re: Lean burn? If it runs well up to 5 psi boost and then misfires, it might be lean. But it could also very well be an ignition problem. This is a classic ignition problem description for our trucks. What's the plug gap? Drop it to .025 just to be sure. Like Don said, set the fuel pressure...

Re: Lean burn? There are some things that would really help understand what's going on. Do you know the fuel pressure, and is it increasing with boost as it should? Since it wasn't mentioned, your truck must not have a wide band O2 sensor and any way of reading it. This would tell you what...

Re: internal engine questions Regarding higher flow oil pumps, be careful. High volume oil pumps put more load on the distributor drive gear. I have a Melling 10552 pump, a mildly larger oil pump, only 10 or 15% more volume. Nonetheless, in two years, mine severely wore the distributor gear...

Re: Cruising rpm typhoon Looking at TunerPro, 60 mph is ~1925 rpm with my 700r4.

Re: Shifting issue from a dig It's a lot of work, but the TransGo SK700-G Shift Kit cures a lot of problems. I had WOT issues with 2-3 flare (or cut-loose) and generally slow shifting. Now mine's better than new. I didn't know the 700R4 could shift so quick and smooth at the same time...

Re: Warped flexplate? Videos, updated. If it only correlates to road speed, not RPM, and it's in the seat of the pants, not steering wheel, a lot of stuff has been eliminated. You've tried three sets of tires and wheels. There's not much left except driveshaft and rear axle. Yes, bad shocks...

Re: Another Noob! My "new" Ty from Chicago Re: Another Noob! My "new" Ty from Chicago The coolant systems of the OEM intercooler and the engine are almost completely separate. The only common point is the puke tank. Unless you see rust in the coolant of either system, I would just drain...

Re: 93 Typhoon Missing at idle, drives fine. Yup, it's a good possibility you've found the problem. A vacuum leak there can play havoc with the idle. It happened to me. Before long, you might also have a coolant leak, or oil leak. If you keep driving it, keep an eye on the dipstick to make...

Re: rear axle info and why we have off set wheels Track width and axle width, flange to flange are not always the same. Sometimes, but usually not the same. Track width is center of tread to center of tread, not flange to flange. Maybe that explains the difference.

Re: What did you do to your SyTy today? (part 2) Installed TransGo SK700-G Shift KIt. Wow! What a difference. WOT 1-2 was sluggish and late, 2-3 had a "cut loose". I don't know what deteriorated, but their Tech line said it would fix it, and it did. Now all shifts, especially WOT, are...

Re: WTB: GM CV-Axles You can get these anywhere. I got mine at Autozone. The first set lasted 10 years before the boots split, and were replaced under the lifetime warranty, no problem. I've owned my Ty 23 years. The aftermarket axles lasted as long as the OEM.
