Imo, with cams, you are building less heat. Are you e85? If so I would drop at least to a 2.7

 

Sorry the opinion is dropping pulleys. With a ported head and cams you will build less boost (but better cylinder filling) so it builds less heat was a fact.

 

that is correct i will be boosting less. as for the s/c making more heat though i think it will, as the ati makes the pulley act like its a size smaller, which i think i will be ok with

 

The heat is manageable. I am on a 2.7 cams and ported head and not an issue. I am running e85 but you don't see that on the aeroforce. I will be rebuilding the SC and going to a 2.5 before long. I think the heat is from compression of air mostly

 

well e85 doesnt help with intake temps but more allowing you to burn cooler and run more timing - whole.other thing

what cooling mods are you on?

i got meth injection, intake manifold spacer (gonna ditch it when the heads off since john says so lol) a dual pass, option b and extra heat exchanger

from what i understand the main heat issue is its a small blower being spun past its limits it generally quits making power past 14000 rpms or something like that

 

Its also due to the blower spinning harder. the head and cams likely help but wont eliminate the problem.

 

I wouldn't ditch the spacer. When I was SC, I seen a noticeable difference. I wouldn't get rid of something you already have and isn't giving you any problems

 

idk if its helping or not but really im worried about leaks (no boost leaks yet)

mrb really hates these things tho

 

It's going to seal up just as well as any other gasket you put on lol. I also have the phenolic on my LNF and haven't had any problems. To each their own tho

 

Standard cooling mods Inluding phenolic spacer. Tempe never get to 150+. Only get to 140+ when it is 100+outside.

 

I also don't have meth in. E85 does have a cooling effect. It is just not measured because of where it is being injected and the location of the temperature sensor (on map sensor)

Also, I plan to keep the phenolic spacer. It seems to help from what I can tell. Cruising tempo stay around during 10-15 degrees above ambient on the hottest of days

 

why would it be bad?

 

Phenolic spacer? Some claim it doesn't do anything. Others have boost leak issues but the only time I had a boost leak issue was with the crappy zzp gaskets. I got the go ones and have had no issue

Gm gasket

 

no **** really

 

as close as the injectors are to the valve the actual cooling that e85 could do is an extreme minimum but what it dose to is lower the combustion temps as it is a cooler burning fuel

 

Allowing more timing without knock right?

 

yes but just think if the injectors were farther away from the head how much cooler the iat2 temps would be

 

Geez , what's that about?

 

Isn't all the effect of cooling done by the fuel evaporating? Isn't it completely evaporated from sitting on the valve and combustion chamber temps? I am asking because I don't know

 

Idk what it is besides a cooler burning fuel either way it deals with different things than intake air temps affected by the supercharger

i may be adding e85 into my build too by the way guys i'll just need to get some 80#'ers then maybe i'll make above 280 wheel

i also may ditch the meth injection; its too problematic and hard to tune for; i'd rather just have a kickass cooling system. i may copy mac gen blackwater and throw a fan on the heat exchanger do a flow through setup and call it a day

 

that's the gist of it

 

Yes, go E85. Best thing I've heard in this whole thread lol

 

yayyyyyy

its so iffy though. closest station is 10-15 miles away from me and i worry so much about getting stranded with no e

 

10-15 miles?? That's it??

Hell, I drive 50 miles for race gas (just found a new station 17 miles away though).

Go E-85 man.

 

How many stations are near you rice? 10-15 miles isn't bad as long as there are some in a few different directions. Keep a couple cans at home if you fear running out.
