time to get to work! The major areas to improve upon were suspension (SPL + Moton), aerodynamics (nascar splitter + sheet metal), cooling (v-mount), chassis stiffness (bracing + eliminating bushings), fueling system (Surgetank + dual 044 bosch pumps), and turbocharger response (prototype twinscroll borgwarner)
FUEL: Needed to beef up the fuel system heavily to make 700whp on E85 and not run out of fuel under hard-G turns when the fuel is away from the pump pickup.^^^this is what motec recommends ^^^hand fabricated, welded by Joey
^^old subframe that i dropped out of the car ^^^added heavy gusseting + support brace
^^^these things are by far the best value of any subframe bushing ever!! i can not stress how badass these things are, and as long as you toss them in the freezer before the install they are UBER_EASY to pop in! Best of all, if you use it with no spacer, your entire subframe will move ~13mm closer to the chassis - raising ALL inner pivots up and dramatically improving suspension geometry
^^^installed, full droop looks like a mini rally car!
Spindles:^^shock mount is perfect, i screwed up the toe rod mount location and will fix that this weekend^^^upper shock mount
and of course i wanted to eliminate the bushing in the upright, so i was lucky enough to find "2fast240us" who had a set sitting around! THANK YOU 2FAST240US!!!!!
RUCA: ^originally i was just planning on adding this heim joint to eliminate the bushing... but then i saw how SICK the SPL RUCAs are, and how much extra strut clearance they provided and i had to swap over - especially since i want to run my shocks inverted, with the spring on the bottom (less unsprung mass = better handling)
^^^showing how much cleareance the SPL RUCA's give and how i can now run my rear shocks inverted
^^ride height, you can clearly see the SPL toe rods also with adjustable height
Chassis: the car already had a full cage and was fully braced, but the cage did not pierce the firewall and connect to the front strut towers. I wanted to reinforce this area, and simply welding in a pair of braces works wonders. BOLTING THESE IN IS WORTHLESS
COOLING: it is simply unbelievable how well this vmount is functioning. The coolant temps are down about 25 degrees Celsius (E85 helps too) and IAT are the same! very very pleased with the result so far. Will wrap up the final ducting and plumb for the new turbo next week.
Also you will not that i am ready for battle with a 1.5" steel bashbar protecting the front end from any "objects"
here is the integrated bubbler tank/overflow during fabrication, saves space and is very functional - eliminates any air bubbles getting in the system!
AERO:^^^showing the flat front, cutout for the oil pan, and the NASCAR front splitter ^^joey welding in the belly pan mounts/jackpoints ^^^kinda looks like an RC car from this angle
inspiration for the aero comes from:^^borrowing some aero tips from these guys
