Cool? no, that's not cool. That's hot, really hot. Probably the upper end before you start melting stuff or stretching studs.

TalkingPie

Nice car.

Question: How do you get those modifications past TUeV? Do you return to stock for inspection?

Mazdaspeed_Miata

@18psi: Really so hot? Before I installed my 3", I measured 1020°C before turbo. Like I have written, the engine is total stock, even the head gasket is the 1st one.

@TalkingPie: Thanks!
Of course I don't return to stock for inspection Nearly all parts are signed in the papers, so nearly 100% legal. Some things like HKS blow off or the carbon fibre head light cover are not legal, but that is not such a big problem

Yes, those are high EGT's, but for a pull like that, probably normal.

1868°F is pretty hot.

It was a bad joke about all the left turn signals.

TalkingPie

FYI: In Europe, and Germany in particular, the left turn signal is a polite way to say, "Hey, get out of the left lane, please. I'd like to pass."

It's of course useless here in North America, where any such request is seen as an impingement on freedom and liberty, and thus, ignored.*


*This assumes that the traffic ahead is aware of the existence of a rearview mirror in their car, and that it's aimed to do anything other than check makeup.

I remember asking Keith at FM about the FM-2 turbo kit and he wrote backing stating it was possible to do 165 mph from that kit.
He never did mention anything about transmission or differential, but I do know that with 250 whp the MSM 6 speed transmission and the 3.63 rear end makes a good reliable combination.

With a 5-speed, 3.909 rear end and 195/60/14 5 tires I have had my car on the limiter at 7200 rpm - a calculated 156 mph. The gps recorded a top speed of 145 mph. I always assumed the remaining rpm were eaten up in tire slippage.

Can you explain how a tire can behave as if it were a smaller diameter at speed? If anything I would expect it to grow a little at high speed.

The distance from the ground to the hub decreases at speed due to tire deflection.

Try telling that to a top fuel dragster.

I'm with phildent on this, I think the tire would tend to grow at high tire rpm, although I would expect this to be limited on a radial tire.

Seefo

tires have a different radius between "unloaded" and "loaded" parts (loaded between the road and unloaded between the fenders). At high speeds a section of tire will go through that transition a lot more frequently. so the actual radius approaches more of the "loaded" radius than unloaded. There maybe other factors at work too that increase the deflection.

to exaggerate this, imagine driving on a tire with no pressure. Its radius is different on the weighted part vs. unweighted. Hence why they suggest higher tire pressures when driving at high speed on the autobahn. Tire rack has a tech article on this.

Not sure about top fuel dragsters, but this is how normal tires work.

phildent

My reply was completely tongue in cheek.We do not run wrinkle wall slicks on the road/Savington and seefo are quite correct,
If we spin a road tyre from standstill in 1st the tyre will grow and the contact patch decrease,however at higher speeds aerodynamics start to take effect.The car will have more downforce at higher speeds and this will continue to increase as the speed increases.
So effectively as far as the tyre is concerned the weight of the car increases as the speed increases,and therefore the rolling diameter of the tyre goes down as speed increases.

Oh man, that car is full of win

All those gauges, and the sti intercooler so worth scrolling through this!

Mazdaspeed_Miata

Thanks, I also love my gauges a lot




I have also done a little brake upgrade last weekend.







And maybe someone is also interested in a picture of my engine bay.



I am using a Begi S4 exhaust manifold. But I have to say, that this is the 4th one. The 3 other one's cracked at different positions.



At the picture you can also see my 2 EGT sensors. 1 at the collector of the manifold, one at the downpipe directly behind the turbine.

Best regards from Germany!

10AE have a 3.9 torsen

I have a 3.636, check speed diferences:

iTrader: (2)

He is in Europe dude. 3.6's are the most prevalent there.

phildent

Brandon is quite right,6speeds in Europe,includingUK,had 3.636 diff and 16 inch wheels.
I have thought of sending a container load over to you guys since they are less than $50 over here.
