Yeah - still have stock headers. No reason to change until the SC came along. Would be interesting to see who has done headers with the SC - I'd like to see what real improvement in bhp it would result in.

I was very happy to be able to get into the 12's. I think a stock tip will be more like 15's or 14's - and I was hoping for 13's.

So lets say hp is around 340 - what bhp figure are you other TPC guys getting? Who's getting close to 400bhp as advertised by TPC?

Hi haygeebaby,

I managed 12.6s at 113.76mph on my Tip in std trim which is about the same as you. I agree the sc really works with the tip. Not tried it since a little lightening and the a/w injection being added.

Cheers, Mark

Those are fast times! Stock STI or EVO would do around 13.5.

You're right, my mistake....the 13.8 is for a manual C2 as tested by Road&Track. Car&Driver have tested a Targa Tip @ 14.3 meaning a lower weight non Targa tip should be capable of something in the region of 14.15 .

A 12.9 ET means around 373HP in this case. 12.6 is around 398HP.

Testing conditions (temp, humidity, altitude, barometric pressure) and vehicle weight vary so power calcs are an approach. An insightful approach none the less when using the correct data input

I thought you might be interested in the test run from my gtech which gave the numbers I quote above,

BR, Mark.

the last time mine was dyno'd came up at right around 360 with sport cats. dyno curves here:

Ok - while I'm waiting to get my dyno done - in another 2 weeks - I've decided to gather as much data as I can to see what everyone esle is getting with their TPC units. This is a pretty crude investigation as different dynos are being used, some cars have the older setup, some cars have no intercooler, there are even results from early TPC beta cars, and 3.8 cars with the SC installed.

This is the data I can gather on this forum and from some magazine articles. Perhaps the results gathered will shed some light on the potential of the kit.

So if you take just the non IC cars you get an average of 312rwbhp and 278rwftlb.
But I know timpsu had an IC on his car. mpb993 is running meth on his car. Their figures are close to the average with no IC - but they have IC or meth.
Clibs car with the IC is the strongest at 357rwbhp and 309rwftlb. Very close to TPC claims of 355 and 333.

Ken,

The interesting dyno's are from 9M, showing flywheel HP, they are the same as mine 354 BHP. Rear wheel losses can be close to 60 BHP, so for a better comparison it would be good to see what the other SC's are delivering with Flywheel BHP as light weight fly wheels can make a difference. I am sure you will see 370 to 380 BHP with protomotive software and bigger injectors.
Interesting spread of power gains with different set ups.

haygeebaby

Okay gents - I'm just about to pull the trigger on the meth kit. Will be going with SnowPerformance unit. Does anyone know where to get a smaller pulley from ?

camlob

Yeah good observation. I have similar rear wheel losses.

axl911

Haygeebaby, can you post pictures of how you mounted the intercooler pump?

How are you planning on installing the AW injector? Pre or post supercharger?

haygeebaby

Sure man - anything for you dude.
I've mounted the pump below the water tank. It just fits in the cavity and sits in the wedge area created by the upper valve cover.
The pump gets megga hot - but it's been working great so it must be designed to take the heat.

1st pic shows old pump vs new pump. Huge difference in cooling capacity with bigger pump and additional heat exchange. Its getting warmer in Perth, but on long drives I always touch the water tank, chargecooler, and intake pipe. They are always cooler that the other parts in the engine bay since the larger pump, additional exchange, and FPR was installed. Deffiently more efficient now vs before.

For the 12v for the pump I'm using the power from the rear demister relay socket. The button for the demister is always pulled out now. Could not use the 12v from the heat bypass pipe becuase it is always on.

haygeebaby

For the meth kit - I'll put it post supercharger - on the intake elbow pipe that feeds into the TPC intake manifold. According to MPB - this was optimal for him.

I'll do the same - and also use a single injector - 50/50 meth - with the resevouir located in the frunk. I'll run the pipe down the left hand side of the car.

Not certain on where the meth pump will be located - but at this point I would assume on the left hand side of the engine bay. There is a lot of room here and it's a logical location. A custom bracket might have to be fabricated - also one for the front tank as well. But I need to have the unit in my hand and test out where is the best location.

I'm going to run it off boost instead of MAF. I think spray as soon as boost hits 4.5 or 5. I really need to see how the boost comes on and off while the car is on the dyno. Boost is funny - it just tapers off as the revs go up.

I want to get a slightly smaller pulley in - since the car has chargecooler and meth - it should be able to take some more heat. I also want to get the meth kit in before the dyno. Which is a few weeks away.

After this it's a matter of doing some fine tuning with Todd at Protomotive and then another dyno to see what is cable from this TPC/Proto setup.

MPB993

Hi haygeebaby,

I've been running pre SC for the past 50k miles. No issues seen so far with the SC but if you have a chargecooler most suggest it is best post charge/intercooler as it is better to take the initial heat out with the cooler and then further cool with the w/a but I do not know what this will do to the ignition or advance requirements. I would be really interested to see what you get as I have a chargecooler sitting in my garage asking to be fitted :-)

I have had some ignition issues when I ran it with too much water.

BR, Mark.
