ERA 753 - Final Assembly in Progress

[Kramer]

Hey Fred,

Awesome Cobra!!!!! Since you seem to have way more experience that I do I have a question for you. I am running the larger TWM airhorns on my car as well. For now, I had AL at thor motorsports help me mill the the horns on the bottom to be able to place a screen between the throttle body and the horn. My Question for you is...are you planning on running any filters. If so, what are thinking...I have found anything I really like yet that looks good, breathes right, and fits under the ERA hood. Any thoughts would be appreciated as it looks like you have the larger horns as well.

Great looking ride,

Kramer

Hi Kramer,

I had a set up mesh screens made that go between the horns and the throttle bodies. This will keep the big stuff (small stones, etc) from getting into the motor. Given that this is a limited use car and will not be driven in dusty places, me experience is that this will be OK. You'll also notice the tennis balls shown in my previous post. These are mostly to protect the motor when the car is sitting or when I'm working on the motor.

Here's a picture of the screens that I am using.

Fred-
Could go sandwich a very thin piece of foam filter between two mesh screens? I changed the air filter in my lawn tractor yesterday and it uses a very thin foam filter with mesh on the back as a "pre-filter" before you get to the main air filter. I think something like that would work pretty well.

Chaplin,

Problem is that an FE intakes alot more are than a small engine which can use foam filters. My guess is that an FE would pretty quickly swallow the foam?

Very impressive!

Fred:
How about placing the thin foam on top of the screens to keep them from being sucked in?

Well, there are others on this board than may have better insights than I du but I would guess a big block would draw enough are to just stred the foam. I think that TWM dies make some horn covers that use a somewhat less restrictive filter material. It probably would be a good idea to give them a call and discuss it before trying anything. The last thing that you'd want to do is to suck the foam into your motor.

I agree a FE would suck in the foam, that is why I suggested sandwiching the foam between two pieces of mesh.

Yep, this is one of those "super builds" that comes along every couple of years. Kinda reminds me of Turk's....

Yeah, it does.

I hope you keep yours a little longer than he did.

Well we reached a milestone in building our ERA today. All of the work to fully install and connect the motor is done! Progress since the last update includes:

1) Installation of the headers and sidepipes
2) Installation of the expansion tank, heater/radiator hoses
3) Filling and bleeding of the cooling system
4) Correction of a problem with the gas gauge (the pickup tube in the tank was interfering with the sender and causing the gauge to stay on empty - had to drop the tank and R&R to sender to adjust the tube)
5) Powder coated the alternator brackets we fabbed and installed the alternator for good.
6) Polished the exahust head shield aluminum covers and reinstalled them.
7) Reinstalled the hood.

Here are some pictures of the car just prior to and after installing the hood.





Ron, this is the picture that we've been waiting to see. The motor in the car with the metalized hood installed. It sure looks great!



Now its on to the electrical work for the EFI. I'm going to start building the custom EFI harness tomorrow. ERA also fabbed a nice custom switch setup to hide some extra control switches under the dash. I'm going to expand it to include switches for the following functions:

1) Battery cuttoff
2) Red Dash Light = Service Engine Soon Indicator/Shift Light
3) Fuel pump automatic/high speed
4) Launch rev. limit enable
5) ECU Data Recorder/Electronnic Traction Control 1/4 Mile Mode Enable

Peter, you gotta find me a set of rear wheels!

Fred its just OUTSTANDING!!!!!!!! Its one of the most impressive ERA's I have seen and like Madmax said " It just keeps getting better"

Hi Ron,

Thanks! You'll be happy to know that I tried to hood on the car will the engine in and all of the accessories on. It looks like we are fine with the shelf under the scoop the way it is. The most forward injector stack seems to have a clean flow of incomming are (just barely). We'll be sure when I can drive the car but it looks like we're going to be OK.

I have similar screens b/t my airhorns and my throttle bodies but that's it. For when the car is sitting, I also used the tennis balls but I have moved to small round filters I cut out of a humidifier filter (they look like little biscuts I push into the horn). Again, I only use them for storing the car. I have accidently started the car when they are in and they seem to quickly pop out.

If anyone has any ideas for some kind of "sock" like filter that is heat resistant and looks good, I am in.

Apologies for highjacking the thread Fred...Again the car is AWESOME.

Incredible!!! You are setting a new standard. Are the sidepipes stainless steel? I would be afraid to drive it.

Yes. the sidepipes are polished stainless steel.

I have seen some chrome header tanks around.... but as you say the contrasting gloss black is great...if there's poss that they crack best not go there!

You should have the steering rack centered with wheels straight so as to have equal steering radius (left and right) for each wheel. If one wheel steers sharper than the other you may have a rub. You must also have the wheel/spring compressed to correctly check for alignment (and rubs). Just make sure you do all these basic adjustments. ERA has built close to a thousand Cobras without these tire issues.

Is this possibly something that relates to the updated body, or possibly the steering and mounting system changes?

How common does this appear to be?
