+1. I had to learn this one the hard way when I was alot younger. I started out w/ my FC when I was 24 and I went through two motors by the time I had just turned 25. The car sat in the garage for 6 months (dead) collecting spider webs on the wheels all because I wouldn't do things right on it.

Even though there's still very few of us who use it and therefore, from a community perspective, it's in its infantile stages, AI is showing a tremendous amount of promise already and once it's become a part of the garden-variety modification paradigm, alot of the blown engine stuff we still see in 2008 will diminish quite a bit.

great, great read!
i guess i really never paid attention to heat as much as i thought....
im shooting for 400WHP on a 62-1 either late summer or early next spring and i did some cooling mods....
koyo rad
wrapped DP
gotham racing turbo heat blanket
i monitor EGT's pre turbo using a pineapple dual egt gauge (even though the front doesnt want to work!)
maybe over the winter or late summer im gonna send out my DP and exhaust manifold to have them ceramic coated.
but is a dual oil cooler necessary?

sure anything can help but as previously stated, the stock is pretty big?

what about adding water wetter to the antifreeze???

and i didnt have a clue either on preturbo EGT readings...

i normally see 200-205 water temps with 85 (cold days) to 100 AIT on my car with LITTLE boost....these were datalog runs not long boosted beat on the car runs....

 

I ran 22psi for 2 years no injection, my set up is errily similar to busted7's
alot of heat shielding, stand alone haltech e11 etc.. my setup is in
the post set up. High boost is possible and can be reliable- it's all in the
details. I'm going higher compression, larger turbo so 22psi on pump
days are over- for now.

 

Hey boosted7,
so you did ceramic on the hotside and use no hotside blanket? I like it!
I hate the blankets- who did your coating?

 

Brian you call chasing pump gas with alcohol a 'heavy alcohol' user!

 

Comparatively speaking, I am a heavy alcohol user. Not heavy compared to, say, Jose LeDuc or others that use 8+ 1600 injectors, but we're not talkin' about race cars here, Mr. Anderson.

so this shield made a big difference?

 

I would think it would make a substantial difference. Consider where it's located and what it's function is: to deflect radiant heat coming off that stove of a turbocharger sitting right next to it. You can have the best intercooler in the universe but if you don't block radiant heat being spat off all of that cast iron exhaust stuff then you're wasting energy because the manifolds will heat-soak and heat that charge right back up.

Yes i did only ceramic coat the hot side, down pipe is s/s coated and header is 2000.00 degree black. Had the coating done in Joplin Mo.





The two shields you see have 1800.00 degree dei shielding on the back side and you can put your hand on the intake anywere after a long trip or a run down the track and it will not burn you.
I think this prevents a difference in air temps that can cause detanation when the fuel and air get too hot!

And i have a secound gen that i run methanol on and its just crazy how cold the temps are. It made a water puddle on the top of the block from sweat comming off the blower.
[till i blew the blower up and realized it was not the way to go]

The oil coolers play a big part as well, keeping the oil cool helps keep the block cooler and of course thats were the important stuff is!
Theres just a lot of little things that add up to one big picture and im still working on more of them!

 

im gonna search for this stuff....
happen to remember a link or where you got it?
so a shield like this and maybe one over the DP would be a good idea huh???
BTW, bad *** setup!!!


makes total sense brian!


looks like id have to take the turbo and the exhaust mani off to get it to fit right.
what gauge of metal did you use? or is that aluminum?

sorry for thread jacking classic......

 

Jegs/summit have it its adhesive backed.
The shield is aluminum 0.32 i belive but its just there to hold the dei material.
There are bolts or threaded holes there that work good for holding the shield.
Also every setup will be a little diffrent so you will have to make it fit.

I cant guaranty how much it will help but it cant hurt! And i know the engine temps are alot better than before.

Someday ill get someone with a video cam and do some show and tells on the temps and post them if i can find the help! Im barely able to post a picture and there too big.
Thanks for the intrest and comments us old people like that!

 

Pitures after 14 months of use:

 

I love this thread, pushing the limits of rotary output on pump. I really think
we can get 600whp on pump- no injection- it's coming!

 

Its not going to be me im working on getting the best 1/4 mile time out of 494 h/p maybe 500 with new plugs.
Ive gone 10.8 but im working on the diff, suspension, clutch, tire combo, and driver mod, im hopeing to get 10.6 with a/c, power steering, cruise, at 2740 lbs.

After that i have a car sitting in the tralior with new everything that i need to finish when i get the money!

Ill let someone else go for 600 h/p like crispeed! Probley already done it!

 

hey busted7, did you run the 10.8 on 20psi and pump? or more boost and
racegas?

 

Don't apologize there's good discussion going on

Great stuff.

 

Busted7, where is that shield for the LIM bolted to? Also where did you buy the aluminum sheet from?

 

Yes on 93 oct, what happened i just got it tuned and had 500 miles on it and meant to put a 14 lb spring in the wastegate but i got the wrong spring and its 20 lb's.
I went to the track and was going to watch only but was pushed into running, the first run was in the 13's and booging bad the secound run was in the 12's but still boogd of the line the third run i decides to let it rip so i launched at 7800 and ran a 10.8.
Ive run 11.6 on street tires with a 2.0 60 ft and 10.8 and 10.9 regulary on the et streets.
And have raced on the street off and on with good results.

 

The egr block off bolts work very well and are in a good location!
Aluminun was bought at a sheet metal shop and is whats called a drop or a piece cut off of flat sheet.

 

im at 460 miles on my rebuild....boy i need it tuned!!!
im anxious to see what this 62-1 is gonna do.....
id like to get the cooling issue a little safer first....

ive already got my DP wrapped but id like another layer...gets kinda warm in the passenger seat....i guess ill order this and some more wrap...after all what can it hurt?? in this case more is better....

 

The turbonetics 62-1 with 96 hot side has been pretty good to me it spools nice and pulls hard to 8,000.00 and 494 h/p at 7500.00 and still pointing up when the dyno shut down the reading!
Good luck wih it!

 

Thank you, I think that it a great idea of putting a shield there due to the turbo being right next to it.

 

The dei shield material is self adhesive on one side a lead like material on the other with fiberglass in the middle and gives a 1000.00 degree's of protection DEI 1010412 summit racing.
Sheet metal snips cut it pretty good. Oh the adhesive is good to more than 400.00 degrees.
It could be applied directley to the motor or intake but it can cause heat retention as well as reflection thats why the shield and air gap.

If you were shielding the body you can apply it direct but it works best with the air gap.

 

Thoughts on plugging the little holes in the exhaust ports?

That must trap some heat which would translate into warmer coolant in those regions...







EDIT: Granted, I haven't seen "overheating" in those areas, no blueing or anything or that nature, but there must be a little turbulence on them which may slow down exhaust near them and heat the sleeve that little bit extra. Note - thats all theory I have no pratical/applied experience with this possible mod.

 

Once again how could it hurt but im sure there is a reason there there in the first place. It looks like a good place to create a hot spot.
Mine on the race car is removed but its on meth.

Just dawned on me what the purpose might be, its probley used to aid in emissions as in helps burn up fuel vapor?
