FE Technical Forum / Evans waterless coolant in FE.
« on: July 19, 2015, 12:48:49 PM »
I was wondering if anyone had tried Evans Waterless coolant (NPG+C) in an FE, specifically an all aluminum FE and the results. How much did it raise operating temp over ethelene glycol water mix? Would you use it again? Did you run normal pressurized system? Is the NPG+C the formula you would use or would you recommend a different formulation?

Mark,
Since my heads have rectangular exhaust ports which measure 1.375  X  1.937, would there be any benefit to running rectangular tube a certain distance before transitioning to a round tube or are you better to transition to round immediately?
Based on the exhaust port size would you use the slightly larger 1-7/8" or smaller 1-3/4" or do you use thicker wall 1-7/8" to get area similar until first step?

Mark,
What would you charge to build a set of headers for this combo?  Looks like you use Stainless? Do you wrap them to reduce engine compartment heat? What do you wrap them with?
Thanks, josh

What does everyone familiar with the FPA-Tri-Y headers think would happen if I was to take my set and modify them with a longer tube straight off of the head flange and then a gradual curve into the existing header, thereby eliminating the tight turn normally there for fitment in cars with shock towers? Would they be adequate for my engine combo?

Barry tried both my FPA's and his Dyno Header on my engine and the results are as follows:

FPA's=540HP@5600,  547TQ@4900

Dyno=553HP@5600,  555TQ@4900

Survival provided the complete custom Hyd. Roller Cam/Lifters so I would have to defer to Barry on the brand of lifters.

I was actually going have the FAB shop build my headers, but after I sent pictures and he realized I had inner fender panels, he said he wouldn't.
His recommendation was 2-1/8" X 34-36" primary not more than 2" straight off the head with a merge collector with 3-1/2" outlet.
I also called REF and he said 2 to 2-1/8" primary.

Ross,
Thanks for the suggestions.
Did you run your exhaust out the back?
I will see what I can fit with the Heidts suspension. The IFS and triangulated 4 link reduce clearance especially above my 9".
Thanks, Josh

Hello My427stang,
Thanks for taking the time to generate those numbers.
I really appreciate it.
Your numbers sound more like I expected.
Based on your experience is there a point I can drop down to 3" or smaller exhaust without a penalty on performance or would a x-pipe at the end of the 9.7 or 19.3 long collector be helpful or is it best to keep 3.25" or 3.5" exhaust all the way out?
Thanks, josh

Hello Barry,
Thanks for the response.
Do you recommend a certain length primary tube? what type of collector and diameter? How long should you keep the header tube straight off the head before you turn down?

Hello Faron,
I know your are correct. I will have more than enough power as proven by Barry on the Dyno.  I just want to optimize the configuration before the final install. 
I hope with aluminum motor, triangulated 4 link, 285/40/18's and intelligent traction control, I will be able to put most of the power to the ground in a controlled fashion.  I figure if the GT500 hooks pretty well on these tires considering the weight, the Fairlane will have a decent chance as well.  Only time will tell.

Thanks everyone for your comments and suggestions.  I really appreciate it.

Hello Barry,
Should know shortly how the 4500 performs. 
With all of your experience, what do you think the best header design to optimize the performance would be.  If I am going to build them, I only want to do it once.  without the shock towers, I can hopefully follow the port roof straight for a fair distance before turning down.  I had one header shop tell me 2-1/8 x 34 to 36" with not more than 2" straight pipe off of head with 3.5"merge collector. I might be wrong, but I would think you would loose to much velocity with that size tube.
Thanks, Josh

Thanks, I will consider your CAM comments if/when I change it.

Barry confirmed
Chambers were 76cc
The quench was +/-.041  to .043 - we target zero deck

Dyno headers are far from optimum for this engine - 1.750 primaries, 3.5" 4-2-1 collector, +/- 37" length

On the cylinder head sheet from KC it says
"Mill Heads clear-78cc"
"CNC Work Complete Stage II"
"valve job yes, face and backcut yes-30 deg"
"additional work bowl blend - restrictors 0.070"
"coil bind 0.0800
"Assemble Heights 2.035-2.045 150-155 ?Sut?
"spring pressure 405-410 @ 0.600
Cam shaft is comp cams PN 33-000-9  SN E 7837-14
grind FB 3018R/ 3039R HR113
gross valve lift 0.643/0.637

valve timing open @ 0.050 int 10 btdc 52 abdc
these specs are for cam installed @ 111.0 intake center line.
Duration @ 0.050 242/248

Barry Said cam installed 110 2 degrees advanced on timing set

The intake was port matched by survival as a 4150 flange.  I just opened it up to accept a 4500 throttle body but haven't run it yet.  I had several people tell me that the plenum was too small and that I needed a larger throttle body and injectors to hit over 600 hp.  I know jay says I should use a larger cam and go solid but if possible I would like to stay hydraulic for now.

Thanks for all the suggestions. 
This build was nearly identical to one that KC did for a cobra other than the fact that the cobra had stack injection.
This build yielded "654HP@6000 and 633TQ@4400". I didn't expect my numbers to be as good as stack injection, but I did expect them to be over 600HP.
Is there a better hydraulic roller cam that could provide the performance I expect and still have decent street manners? I have Erson Roller rockers.
I did this build based on Joe-JDC results with these heads.
Joe, what do you show for the intake and exhaust volume?  I asked KC but they didn't know for sure.  My numbers we based on KC's estimate in another post.
Thanks, Josh



Thanks, josh
