Supercharged help please!!

mr2drummer · 11-26-2008, 12:46 AM

I have a 88 superchared with a HKS pulley, and everything else all stock. A couple of months ago I noticed when I drive on the highway for 10 minutes or so that my exhuast manifold will start to glow red. I have taken the cat and muffler out of the system and even the flex pipe section and it still does it, checked cam timing, ignition timing, fuel pressure, and everything else there is to check. The car still runs like it always has, it runs perfect just the exhaust glows, Has anyone else with a SC noticed this after driving for a while? Maybe its normal? On mine you cant see it through the heat shield, but if you look underneath it between the heat shields it glows cherry red.
Thanks for any advice...

well i have the mkII so im not 100% sure but i just saw a vid on this and its just the exhaust nutting is wrong with ur car pipping can be thin that it glows cuz its too hot for it thats my guess from what i saw

Not enough timing will cause that, what is the timing set at now?

I don't think its normal for the headers to be cherry, or even orange hot. I had that condition on my SC14 charged motor when it was running like butt. I got it running good now, and they don't glow in the dark. I would suspect the condition has something to do with the fuel air ratio your engine is utilizing.

I have my timing set a 10 deg. I think, its whatever it said on the engine cover and the book. its set to stock.
Thanks

You're not using an MSD box are you? Make sure you have it set at 10* before top dead center not just 10*, not saying that you did it wrong but plenty of people here have before.

Mine only glows after a good, hard drive and then if I bring her right in to park in the shed out back... this goes for both my N/A and S/C cars. Otherwise they don't glow.

how do your plugs look? which plugs are you running?

mr2tim · 11-30-2008, 09:47 PM

Been drivin' mine for 19 years and never noticed but now I'm gonna look.

I am curious, since your running that HKS pulley if your looking at the left notch then it's correct. Looking in the filler cap for the cam indentation confirms this.

When I first bought my car in '89 I heard tell of SCCA racers that ran headers in competition and if they didn't "wrap" the headers, fires were widespread.

An interesting note: when I was crusin' the Internet for a S/C distributor in foreign yards afew months back there were a whole lot of Mark1's that had "fire damages" that melted the distributor I needed?

My 4a-gze parts engine out back was a "fire" engine too.
