What do big turbo Supras taste like?

Besides bigger injectors (I'm assuming 60lb), did you have to upgrade the fuel system to support 17psi? Also, is there a point to where the Evans Cooling Mod kit is needed?

I still have the stock 39lbers. I have 60lb's and an SCT mass air in the box waiting for my Whipple install. Im not real hard on my car so the cooling mod is postponed until I replace the clutch, but Im sure any efforts to keep the rear cylinders cooler and replacing the plastic crap will only help.

Jason too.

My cooling system is 100% bone stock.

They don't taste too good.....because I've never beaten one of em. ****** are faster than the Word of God in a Mississippi wildfire!

That surprises me. I've heard quite a bit how the No. 7 cylinder is pretty vulnerable to detonation when the boost increased. I guess it's just all in the tune. So changing to a lower thermostat like a 160 is not needed?

Nope...but I recommend upgrading the heat exchanger and doing
the evans cooling mod. The aftermarket intercooler reservoirs are
a joke IMO. I'll be upgrading my cooling system soon.

Yeah an upgraded heat exchanger would be a must, especially a double pass through design. If I got a Cobra, I'd end up modding it in a backwards sequence. Cooling upgrades first, then exhaust with long tubes, tires, subframes, and poly mounts. Then it'd be time for a stage IV Eaton with a 2.76 upper and a 4lb lower. In essence, my goal would be a maxed out Eaton car while retaining stock ride quality and handling. If I could get ~ 550rwhp out of it spending $750 to mod the Eaton I'd be happy.

BTW, what's your best 1/4 time so far?

Believe it or not, long tubes are a waste of $$ on a eaton car. Lose hp.

Best to do suspension mods 1st in my opnion.

Fried rice. Makes a nice side with Cobra. Very sliming diet.

You lose hp with long tubes? I thought gains were just modest, maybe around 10-15hp along with losing a pound or 2 of boost from more efficient scavenging and less detonation?

what cam is to big is all someones opion. i know several guys who drive t-rex's in their daily driver. personally i didnt want to go that big and made the power i wanted on motor with a 232/232 600/600 114. dont listen to people who say something is just to big. my car drives fine with 3.42s and i lost no low end. the car will spin at 40 in 2nd on concrete roads. i had a 226 578 114 and it just didnt make enough power for me.

get what you like but a 23x cam with a 600 lift can be tuned with no problems to idle and drive. i was told by people go big with my first cam but the shop told me the little cam would make the power. the shop took care of me and changed the cam for free but not many shops do that kinda of stuff. in my opion though you are wasting time with a 22x cam.

go big and do it one time.

I have seen a gain of about 2hp at the most on a eaton car. Losing 1 or 2 pounds of boost is quite a bit of power (15-25rwhp).

Headers are actually fairly cheap for cobra's, unless you have a kb running 18+psi, they might help more.

5th gear pulls are what kill the bottom ends on cobra's

CharlieCobra03

Yep, if they don't have a cooling mod. I don't know though. I did 5 or 6 pulls to 160 or better BEFORE the cooling mods with no issue. Afterwards, I raced an R1 where I redlined (7K) 5th before going to 6th for a little more. The speedo was well past 160 cause the speed limiter was disabled and the Rev limiter bumped to 7200. I really have no clue how fast I was running but I was starting to pull the bike before I ran outta room and nerve.

True story. This man knows his Terminator ****.
