2JZ MKIII vs 7M MKIII...

[Boost Lee]

Some of you may recall a couple months back, the thread,
"Acouple High HP Supra's playing around"...

Well, here are those two cars, but actually going at it this time. :aigo:

Again,
SuicideSuprA70 (Matt)....white 2J car
and
suprafanatic (Nate)....burgundy built 7M car

(Pardon the annoying 4:3 ratio...I forgot to save it as widescreen version!)

Enjoy!

not bad....not bad at all...7m just needs more boost to keep up lol

thanks for posting nice vid.

 

[super.secret.supra.club]

[Jostar]

2 words, for both of you. BRAKE BOOOOOST

I've actually told BOTH of them before, but I think it's a mental note to some people that it's just going to eat your brakes. :biglaugh:

You've mentioned it a couple times now...
I take it this means you did it often with great results?

BTW, I'm sure he'll chime in to mention it,...But on Ch.1 (15PSI), it now walks all over the road with the GT40.
Can't wait to feel it on Ch.2 & 3. :love:
I hear you're possibly coming up for Chicago this year?

Cool. Brake boosting is awesome, they should do it. There is a noticeable difference for sure.

 

[CajunKenny]

Alright, newb question of the day.

What is brake boost?

 

[Boost Lee]

Brief example...

If you're going from a 50MPH roll...Kick down to whatever gear you'd normally go in,
but instead of holding gas steady, compensate your brake and accelerate at the same time so that you're putting a load on your motor,
building boost, and as soon as you're supposed to go, let off your brake and WOT.

Baaaasically, ride your brake, and give it gas so you stay at desired speed.

I thought that might be what it was. Basically, power braking while rolling. Thanks!

I dare not try it though.

 

[Poodles]

It's not hard

Easy with the e-brake as well, but as our e-brake shoes are thin to begin with...

 

[Doward]

Jeff's doing 180kpa while brake boosting on the Doward 13" BBK Moves pretty good when stepping off at 12psi right from the start!

Now that's what's up! :naughty:
If only I could get my hands on a set of those...

HAHA oh the feeling!

I think John (Doward) may have a few extra sets pm him!

And you guys should really be sporting bigger breaks with that much power, I know those inadequate 1 piston calipers and undersized rotors can't handle a few runs to 140 and down.

Amen to that. But since both of them do have stockish brakes (just aftermarket pads),
High speed runs usually mean to keep plenty of road ahead so they don't have to be so harsh on braking.

John, How well do the 13" brakes of yours generally clear 15" drag wheels out back?
Of course, with backspacing/offset to vary.

Hell yea, brake boosting makes a HUGE difference. I literally stood on the breaks while at WOT. That car will nearly hit full boost while brake boosting.

laggy high-hp car + brake boosting = unbeatable highway monster.

I'm still working on comming up to Chicago, I'll be a married man then.. so we'll seeeee. LOL.

Nice video, no wonder Nate was asking about meth,bigger turbos, and nitrous.

They're just fronts, rears may be in the works though

They fit stock TT MKIV wheels with plenty of clearance but can fit the ribs in stock sawblades.

Hennessy- I took out a ~GT30 STI on 26 psi and meth a week ago, friend behind me said the ass end squatted and I took off. (I was only 15psi)

 

[Mo87NA]

Very impressive. Makes me wonder how my car is going to hold up. I really should upgrade my brakes though
