5858 track times e85 Turbo TA

Do you guys think if I go to a taller tire my 60' will suffer?

This subject is very complex for me! It would seem a shorter final gear ratio would perform better but this isn't the case comparing my engine load/VE curves in 1st, 2nd, and 3rd with load being greater in the taller gear. Best answer I can give is turbochargers do not need the tq multiplication you would need from either a na or blown engine which are rpm dependent to make power.

btw...very good times you have! 1.4x 60' is coming out the hole very STRONG!

the 26" tires seemed to work well with a ~12lb launch, but they spun at ~20lb. I wonder if a 28" tire would've handled the higher boost at launch.

I love how you've made all the stock componets work together and providing the hrad parts to take the hits to net those neck snap'en 60'fts. Are you using the vaccum brake setup? Very nice build & times.

I think using a turbo that's properly sized is the key. A lot of people including Precision recommended a 6262, but I felt like it was too big. I previously was running a 6152, and it felt like it took forever to spool. Yes I'm using the stock brakes, with Ford Explorer Brakes on the rear.

The taller tire should require a slightly harder launch to equal the 60' but the potential is there for it to run faster.

Going to a smaller a/r ex housing wakes those turbos up a lot. Both are almost identical in spool. The 6262 might spool slightly faster with its lighter compressor wheel but low speed performance of the wheels is very close. Both have the same size turbine.

I considered the smaller Garrett housing based off of your recommendation, but still felt like I would be unhappy. Plus I needed a HD actuator for it. How do you think it would've spooled compared to my 5858?

It would have needed 400-600 more stall at zero to spool the same. Garrett .63 on a small cea like yours is a lot of fun.

Dave, we'll see what a big tire does to my car. Id say its pretty consistent...lol

Would there be any negatives if I switched to a Garrett housing? My old ta49 with a Garrett housing spooled ridiculously fast.

I hope you can get those big tires to fit!

Did you install that torque arm yet?

 

[TT/Ameasap]

No. I havnt had time.

Booo! I'll come over Saturday and help you!

That would be awesome, but I just don't have the time. I have calculus, physics and engineering tests throughout the week. Gotta study for these midterms.

Calculus and physics,.... UGH!! I remember those, not fun at all. Good luck!!

I wish I still remembered those...

Isn't working on your cars launch characteristics the same as studying physics?

Applied studies at their best, Hp to weight ratio, drag coefficient, suspension geometry, AFR to boost with multiple fuel mix chemistry, just a start!!! Mechanical & Electrical abilities required! LOL good stuff to keep you out of the bars & massage pylers.
