Good morning!

Here's what is in store for Wilson.
It's a fair bit to chew off, but fortunately the winter is kind of harsh this year, which helps.
Up until now, I'm usually in a rush & compromise. THIS TIME I want to do everything right.

So a general description:

Wilson will be a street legal high performance sports car:
-2750 lbs and 300+hp
-a/c and heat
-Roll bar (not full cage) and adding door bars
-28mm torsion bars/250 lb coils (1.25" lowered), 25.5 & 19mm sways, Bilsteins
-de-powered steering for feel
-Factory power brakes with modified stock brake pedal ratio for 3/4" more leverage & custom carbon peddle extensions to move seat rearward.
-Really struggled with seat choice, but selling my older sparco seats & replacing with new. I love the blue. I was going to go with reclining seats, but it's tough to go back after you realize how much stronger a fixed back is. The Sparco Sprint is a good looking, light seat that feels supportive in the corners & fits my budget, but on long long days of driving, my back suffers, so do I buy the cushions to support the back more? Or save more money to upgrade?
-Really trick "flip up" Momo or Sparco 350mm steering wheel, for easy ingress/egress (whatever that means, LOL)
-Aluminum front splitter & carbon wing. A lot of fabrication is required. Some crazy ideas too!
-Custom dash. Might get it wrapped... Check out the insaaaaannnnne Skull & Roses theme a customer's truck came with.
--Side mirror delete. Lots of aero. I also want big fat tires, but don't know what tires will fit the 1988 n/a? IDEAS??? I'm thinking 10" x 17" rear and don't know for the front. What wheels will fit these cars?

Noah, you should consider spending a little more $ on a better seat. It will enhance your driving experience ten fold. You will not be happy with that seat. The color is cool thought!

The sprint seat is a tubular design. Fiber is better and stronger

Find a set of 2nd hand Kevlar out of date Race seats, I found some Cobra ones which are strong and only weigh 8kg / 17.6lbs each

At long last I now have the rad & a/c condenser tacked onto the frame rails. This and air flow will determine the third tubular crossmember position.

The new intercooler position will require a turbo position change.

Thank you Spencer. Had a really good chat with Mike Lindsey about front mounted intercoolers and a/c. He once had a customer pay LR to install a front mounted IC that didn't fit well at all. Mounted in front of condenser. Hot hot summer weather. POP! compressor line blows.
What happened was the high pressure side got so hot that the a/c compressor locked up.

yikes
that's a concern i've had with making all my **** fit...current "design" has my IC>AC>rad but i need AC more than i need boost... lol
unsure if my hoses are long enough to move AC forward but i guess that's a trivial fix.

This diagram shows airflow in and out of the GT40. Note the vented seats that exhaust through the roof ports. The large door duct is an interesting detail. Also note the brake cooling inlets near the front radiator and aft of the door opening.





Ford of Britain captioned this photo: "The driver's seat in the new Ford GT is air conditioned. Air which is drawn in at the front of the car circulates throughout the whole of the seat to ensure that any perspiration which is generated by the driver during the race is quickly evaporated."

Been thinkin' lately on the under belly.

Startin' to think that creating an arrowhead shape to guide the undertray air out of the car before the transaxle might be a good idea. If the exhaust split into 2 side pipes, that might just do it. Thoughts?

young man we must always keep in mind a simple question...maybe we should get bracelets made up?

"What would Porsche do?"

on their latest-and-greatest LeMans killing 919 they just dump it out the back.
i would be inclined to put it out the back end somewhere that it fits also...think of it as free rearward thrust like a P-51 or Spitfire exhaust
my thinking - Porsche already gave us a "cutout" to clear the muffler/tail pipe, just behind the rear bumper.
maybe you can tuck (tack?) your tail pipe in that cutout and build your rear tray flatter around it...

Good point, but that is also a mid or rear engined car, correct?

also, something that has long been in my mind, a concept that i am not 100% sure of its veracity but it "makes sense to me"..

high pressure air is in front of the car. low pressure air is behind the car (drag).
high pressure air in front of the car gets blown through the grille/radiator and dumped into engine bay.

my thinking is...why not seal the engine bay but make a channel to route that air all the way to the back of the car and dump into the low-pressure zone? methinks that the pressure differential would have 2 effects:
1) would increase effectiveness of radiator by encouraging more airflow through the core (from high pressure to low pressure zones)
2) would decrease drag by more equalizing pressure in front of/behind the car, perhaps making top speed/MPG increase ?

in the case of your experiment, you could put some standoffs (maybe 1-2"?) against the existing body floor and then build your flat bottom below that, unobstructed by suspension/exhaust/brake+fuel lines and other stuff.
