Turbo near BMC Brake setup question

[godrifttoday]

So I picked a manifold a while ago for 20 bucks. It was almost touching before but now I welded another t3 flange on top of the previous one to move the position from the Bmc. So my idea is to run this manifold but I will try to limit any potential brake fade that might occur... I plan on buying a turbo blanket and wrapping the downpipe and also making a custom heat shield probably out of 12 gauge... With the gold reflector tape too... Would this be enough to avoid this problem before it even happens? Is their a replacement Bmc from wilwood or similar company which is smaller I'n size and retains the booster? The brake fluid not sure what to get yet. But it would have to be quality fluid.. For my front brakes im rung 300zx front calipers and 350z front rotors with z32 rear calipers. Any comment on my setup considering how close the turbo is from the Bmc?

The gold foil worked great for me. The manifold was literally less than 1/8" away from the brake lines. It was so close I couldn't wrap the manifold with header wrap or use a heat shield. After a 20 minute session you could touch the gold foil and it was barely warm.

You should also wrap the dp with header wrap since it looks like you have room.

yes i will heat wrap all... thats great news! the foil does work well. and my bMC is from a right hand drive 300zx... btw i cant see the pics u posted

I have my manifold wrapped, then I also wrapped the lines with foil. I have just as much clearance as posted above with a Z32 BMC. The way the S14 BMC is setup is much better and allows much more clearance.

240sxTTC - You should get a LHD booster, it would help since the lines runs on the opposite side.

Not a prob anymore.....no more turbo

Just pull the booster and install a dual master cylinder setup mounted inside the firewall. tons of room then.
It'll only cost you about $500..

^
does it feel like if u have the booster? Any links of this setup

[Matt93SE]

pedal is firmer, but the brakes feel WAY better and modulation is a ton easier.
it's a road race type setup and is all custom.
I'm ordering hte parts for it this week and will post pics when I'm done.

As for looks, see if you can find pics of Dai Yoshishara's brake setup. I called wilwood to ask about master cylinder sizes and the guy told me he just got done helping with the setup on his car and they loved it..

On my old KADET, I ran the thinnest brake booster (non ABS S14 AFAIR) and then made up 10mm banjo lines that went down and around the BMC and re-attached the metal hard lines on the cowel to get the most clearance from a GT35R housing. That with a heat shield gave me the most room and best protection from heat. (heat tape, mat is fine, but air gaps give you the BEST insulation along with airflow to protect against turbo heat.)

BTW - you should put fiberglass insulation on your intake pipe. Most of the heat transfer right there will be convection driven, and gold film has essentially no thermal resistance (thickness and thermal conductivity).

No more Turbo!? Why!?p

IIRC, I think the power to weight put him in a class that was nearly impossible to do well in with a 240. Also had some issues with reliability as well. Had some crazy amount of torque because the power to weight rule doesn't account for torque.

I know....I'm going to make an insulated and pressurized enclosure for the air filter. Trying to finish up manditory safety stuff before my next event like a seat back brace since my FIA seat expired in April. I also had to repair my splitter and make all new struts from my off at the last event. Also I would like to somehow lessen the 90 bend going into the TB. For giggles I took the intake tube and silicone elbow off when I was calibrating and it made +5whp and +12 torque. There just isn't anywhere else to put the air filter that is a relatively straight shot unless I mod the hood.

Exactly....I was in TTS with the turbo engine, which is the lowest wt/pwr ratio (8.7) unlimited class. I was allowed to make 315whp. At 4K rpm it make 310whp and 435torque. It kept blowing head gaskets and the block finally cracked after I O-ringed the deck. Maximizing torque was the only way to attempt to keep up with the C5 Z06's. They are great cars and can fit HUGE meats. Mid-OH has quite a few slower mechanical grip corners (one leads onto the longest straight-away) and they were killing me. Anyways I built the car I always wanted to and fit it into a class, which rarely ends well. After the block cracked, I re-evaluated the car, the rules and the competiton in each class. I then built a car specifically for a class....maximizing the mods per the rules. I think the car has potential to be competitve at the Nationals in TTB. We'll see.

Speaking of that, you mind doing a quick write up of how TT differs between points classing and dyno classing? Are they the same?

I talked to the regional director for NASA TT over my region, and he said I'd essentially have to dyno tune to class. TTA would give me a max whp of around 305 rwhp if I recall correctly. But how in the world can a C5 Z06 also be in that class and make probably 400+ rwhp? Seems it would violate their maximum weight/HP ratio.


Anyway, something I've been trying to find the answer to, and the regional director was pretty.... short on answers.
