Mate, I'm just one of the lucky ones whose job and hobbies overlap.:)

As I had so much trouble valuing her i also put her on eBay here;

A vehicle dyno loads the vehicle to try and simulate the road. You brake the dyno at speed/load points and map the fuel and spark looking for differences in Tq / AFR / EGTs / DET, etc... to get the...

The 0.86A/R housing works really well in combination with the cams to open up the top end. Even with the 0.86 housing if you look at the boost curve on the dyno plot you can see that the boost is...

Heat builds??? Do you mean EGTs, intake manifold temps, compressor outlet temps, coolant temps, underhood temps, etc...?

After numerous back-to-back WOT runs on the road & track the temps above...

In my experience >400bhp on a standard bottom end is possible but only after logging AFR, EGT, Fuel Pressure, Injector Duty, listening for DET, etc... and taking many hours trying to get there in...

The applied 2degs safety margin from det free road to final map should give whoever buys the car enough safety margin.

I had det issues on my Celica GT4 due to the top mount chargecooler. This...

I've always ran turbo cars (Renault 21 Turbo, Celica ST205 GT4, various S13s) and I've driven them all the same i.e. not going max boost/rpm after a long idle or traffic crawl.

Even if you have...

I'm glad you find the plots useful and that they confirm what you've found. I suppose I'm lucky to have access to the kit to collect all this data.

I run a MAF based system, without IAT, but the...

No I had a 0.64 A/R for a while but found it choking teh flow at 25psi / 6400rpm or ~350bhp.

Here's a plot that shows how the 0.64 A/R preturbine pressure varies with rpm @ 25psi. You can see the...

I agree, there is probably more to come with engine internals such as thicker head gasket to lower the compression & run more spark, flowing the head and higher flow intake plenum. They were all on...

There was no chasing a magic 400bhp. We mapped it on the road keeping EGTs sensible (~900degC) and that resulted in the AFR trace you see. We made no fueling adjustments on the rolls just ran the map...

I thought that too, but I actually logged fuel pressure through the whole Rev and RPM range and it was spot on base pressure rising with boost. In the end they've worked spot on for 4yrs with plenty...

Yep she can get lively, particulary in the wet, but even 3rd gear in the dry needs some respect. Not quite selling up as have 2 other S13, but I've finished the development on the S14 which for me is...

I finally dyno'd my S14 and she made;

434BHP/6556rpm & 412lbft/4851rpm @ 1.7bar with 25bhp NOS to 7000rpm
407BHP/6665rpm & 374lbft/4975rpm @ 1.7bar without NOS

The NOS Antilag uses a small...

Hi, I'm taking my 200sx to the dyno on Tuesday at 3pm to confirm the predicted 400bhp. The dyno is near Dagenham in Essex.

I'm running a Apexi PFC, but unfortunatley my 2 mates with Datalogits...

Hi, I'm taking my s14 to the dyno on Tuesday at 3pm to confirm the predicted 400bhp. The dyno is near Dagenham in Essex.

As fuel level drops the pump nosie will get louder as this is less fuel to dampen the noise and the top of the pump will become uncovered.

My track car walbro got really loud, combined with...

I found the problem at Woodbridge Airfield on Saturday.

We changed all the bits with no luck, after about 40miles the misfire returned.

We took the fuel pump out and the filter was covered in...

Thanks for the advice, now got a spare CAS, walbro, sparkplugs, coil loom, MAF and ECU to try. If it isn't one of those I have no idea what it is!

I'll try the CAS first on your advice. Thanks,...

Thanks for the suggestion, but we checked this on the day and all the fuel lines are well away from anything hot in the standard locations. Also checked the temperature of the fuel in the tank by...

Just did a trackday at Brands in out Stage 2 S13. The day went well until about 2pm when it car started to misfie at full thottle. If you backed out to 75% throttle all was OK. Over the next few laps...

Hi, tried searching with no luck.

Whats the tightening torque for the bolts between the bell and rotor (disc) on your S14 310mm brake kit. There are 8 bolts with an allen key head, 2 washers and a...

Passed my MOT last night without a narrow band Lambda sensor....:)

I refitted the standard CAT and setup the car on the wideband to have approx. 14.7:1 AFR @ idle and fast idle. So slightly lean...

Yep engine is standard and done 112k, it's even got the original head gasket...:) Compression is good with no significant oil usage or nasty noises.

Just to update the post.

Ported and flowed the SS exhaust manifold and 0.64 Turbine housing. I ended up making a copper gasket and matching this to the manifold outlet. Using this as a template I...
