IMO people would have far less tuning issues if they always started with a properly pre-heated engine....... This season I did some back to back testing between using my comp heat and not using my comp heat, there was no comparison......Pre-heating makes things much easier and much more stable, no question about it......
I see your point of view, and Montys also, what i find a little curious is that none of you says it prolongs engine life that evryone else is pointing out. You two are amongst the moast experienced engine guys on this forum.

Monty pointed out to me that it would be beneficial for the crankpin and rod, but thats abaout it.

One question, do you belive that it is harder on the rod/pin to run out of fuel at WOT on the straight, than not preheating your engine before you start it cold? I strongly belive that pin/rod gets alot more abuse when running out of fuel at WOT.

running out of fuel at WOT is more damaging without question.....I have never done any longevity tests with pre-heating so its hard for me to comment...However the tune stability advantage is definite and easily proven.....

after break in and pinch is gone i never pre heat my engine, really no need to if the pinch is gone. the pinch is the main reason for pre heating. i can see where it might help a race tune though

A few times this year I have gone out for the 5 min warm upbefor the race and the motor felt a little rich but I opted to leave it figuring I would heat up and level out come race time. Wrong!

Since using a preheater my motors have always been spot on tune while racing. I know within minutes weather it's rich or lean or perfect and have plenty of time to adjust before the race starts.

Money well spent in my Opinion.

I thought you were supposed to do it like the Pro's to get it warm for race tuning. You start it in your pit and rev it on the box 15 mins before your race. Then you move it into pit lane behind all the other pit guys while there still racing and rev it for another 5, then your pit guy walks it thru SILENT check in while you rev it some more. Then back on pit lane to rev another 5 then its off for your 2 minute warm up. LMFAO sounds like an engine warmers a good thing.

LOL, it is hard to pre heat your engine if you run 6 classes at the local track unless you can talk the wife into helping..

Thank you niel. For all your points i belive this is tru. It can make life easyer when you are a racer. I hope you understand what i am trying to say in all of my posts. Many people try to convince others that if you do get an engine haeter, you will save mony on the other end. Is this right? I am in the belive that using you mony on other things that you actually needs to go racing is by far more important than prehating. If you abseloutly need to preheat, go to walmart or even cheaper stores and get a cheapas heatgun. It will do the same but with a bit more work.

I would like to ask evryone here, have you never ran an engine out of fuel at wot? I think moast people have done this, on several engines.

I will let this go now as i think evryone has understod what i am trying to say.

Happy racing evryone!!

The FACTS are:
.Preheating WILL prolong the engines life
.Preheating will give you better runtime because engines use more fuel when they are warming themselves up after a cold start
.Preheating will help you achieve an optimum tune FASTER
.Engine heaters are NOT a marketing gimmick BECAUSE it DOES have beneficial use for its users and does exactly what its supposed to

i never like to run out of fuel, that is almost worst that not pre heating if there is pinch left. at end of tank when starving for fuel it also starves for lubracation.

You do save money in that you do not waste nearly as much fuel warming up your engine...I would say you save about 1/2 -3/4 tank per race........I know it doesn't sound like much, but it does add up.....

Yes, you are right but if you see it in a bigger scale, you will need batteries or electricity to power it up. Maybe you need one more charger, or one more extensioncord.. There are many ways to see it :-)
