Jesus after taking my car for a little drive it's gotta be like 250 degrees under the hood, is there anything i can do about that, i mean one of the exhaust pipes almost touches my oil pan down low, and im sure it heats that oil up big time, will there be any diffrence with my d1SC ?? is there any remendy ?? Most of it is vented through my cowl, but im worried about the paint on the other side.

 

I have the same exact headers and i used Jet Hot coatings. They did everything for $260. It came out great and i highly recommend them. I do not have any temps for you since they have yet to go on my new motor! good luck

 

86irocnj,

Question, did you just install you tes headers and note the underhood temp? Reason I'm asking is that i just rebuilt my engine and I have noticed my underhood temps are around 250 when i'm in stop and go traffic! I never had this problem till i took off the header wrap. I suspect that the removal of the header wrap is what is causing my high underhood temps. But, Im not sure. I did suspect that the headers with out the wrap was causing the high heat, but not sure? Anyway, back to my orginal question, did the high underhood temps come on as soon as you installed the headers?

 

Hey Craiger, i do not have any temp. problems, yet anyway! I guess i wasn't too clear, sorry. I am in the process of doing a motor swap right now and i do not even have a motor in my car, i just got the old one out yesterday. I was just referring Jet Hot coatings, sorry! I am sure i will not have such problems with my new headers since no one complains about the quality, and that the coating is guaranteed to work! I would think that if your heating problems happened after you took off the header wrap, then that could have something to do with it. Good luck and sorry for the confusion!

 

Thanks! I think the removal of the wrap is the problem. I wish i would have put the coating on! I might end up getting the slp 1 3/4 headers and coat them? Winter is opon us so i have all winter to decide. Thanks for the info!

 

hey craiger if i recall i heard you say you could get a good deal on afrs do you have the link for that. thanks..

 

I highly reccommend coating your headers. I've touched mine numerous times with the car running and not burned myself too badly - the temperature difference is very noticable. I've read that coating reduces header temperatures over 200 degrees, and that's a whole lot less heat dissipating into your engine bay and car.

 

I've got the same headers, and mine have the Jet Hot coating. It still gets hot as hell under the hood, but not as hot. I think that the major problem is that there isn't enough air flow through the engine bay to evacuate the heat at city speeds. Mine really doesn't get too hot under there if I'm just doing highway driving, but in town, damn does it ever get hot under there. My engine isn't running hot, just ambient heat from the headers.

 

I suspect my TES headers of causing my car to overheat in city traffic also.

 

it couldnt be your fan isnt good, or anything else. its yours headers

 

Exactly.


Headers don't cause overheating. So, there's another problem. Things do get hot under there it's an engine, more importantly is what temp the engine runs at. Try keeping it cooler.

180* for CC cars
160* for non CC cars
lower temp fan switch than stock.

 

Hey, I was thinking about putting those Edelbrock TES headers on my '89 Camaro IROC-Z 5.7. All headers get hot but I don't have the money to coat them, so do you guys think spraying a few coats of the VHT stuff on will help out well with the heat? OR, should I go with chrome TES headers, so I don't have to worry about spraying them and the put those header "jackets" on them? Which one of the two will do me best? I know it would suck to cover all the pretty chrome up but if that's what I would have to do then so be it (that's if that is a better idea than VHT paint.) Thanks for the help. -89IRO

 

I have the same headers with the VHT coating on them and it appears to be fine. The under hood temps arent too bad.

 

I've used 1200* paint once, and burned off after a month or so.

 

So then would you guys suggest going with the chrome edelbrocks and then put the jackets on if it gets too hot? Thanks. -89IRO

 

They are still going to get hot as hell. If it is like any of the other chrome headers out there, it will turn colors and you would have wasted some money! Same idea if you put "jackets" on them. You can send your headers in used if you wish! I think it may be a bit more. Or the warrantee may not be as long for used headers, or something like that! It is really up to you. If you need them in your car now, do it and if you remember to get them coated down the road, do it. If you really do not need the coating, just install the headers. Point being, they will not stay new and shiney forever, either way. With Jet Hot you just get a guarantee and some lower temps! it is a great product, but you do not need it! good luck on the decision

 

I dont know if maybe edelbrock headers are made different than hooker but my underhood temps arent bad at all with hooker headers...im running a 180 thermo/180 degree hypertech fan switch. Car stays really cool and underneath the hood isnt bad even with stock hood. I do not have the insulation or seal on it but i dont think that matters. Mine is also a mild 305 so maybe it just doesnt get as hot.

 

I have TES headers and they do get a little warm but not enough to overheat the car.... I would say if your going to run a d1-sc that's some major power gain it would be well worth pulling the headers out and having them jet-hot sterling coated... they say it's a 300 degree drop 1 inch from the port. Especially since a sc increases the heat even more. Has anyone ever thought about sending in a supercharger induct tube and having it coated or even the intake manifold? I was just thinking about that the other day.... (I don't have a sc, but I get bored).... I know some people do heat wrap the induct to try to keep from heat soak... just wondering if it would be a small gain to have them coated too.
