Yeah that fueling **** he sells with the kit is bullshit. Better off telling him to stuff it and get your own fuel mgmt.

 

One of the few times where I am able to proudly say,
"Richard, that was well said."

The MP62 hardware looks to be great. I just hope that people use it with better engine management than the PCPro, and not listen to any tuning advice from Tom. But I'm predicting that the opposite will happen.

What did he say, something like 115 pulls on the dyno to tweak the fuel piggy?
And THAT didn't cause or contribute to the motor's failure. Dumbasses.

 

Nice power/torque curves, and not knocking their numbers or the kit, but the car they used did have a built engine (what compression since the 99 was higher compression to begin with?) as well as headwork on the already better flowing 99 head (oversized valves/PNP?) so you would wonder what the numbers would look like on a stock 1.8.

Again, not knocking their numbers or the kit, it looks very nice, just not necessarily an apples to apples comparison with a "stock" engine. Depending upon how much work went into the engine, numbers could be far different.

 

here's the comparison:

 

yeah the comparison tells all.

I noticed it was similar to my turbo above 4500 rpm. below that I am about 50-60 ft-lbs down on the super.

 

What's the setup on that car? I've searched FM's site high and low and I can't find it.

 

Jeremy really didn't give the details. 99 block with forged internals, worked over head, Hydra, 140 crank/65 nose pulleys, 99 intake mani w functional VICS, 01 exhaust mani

**** the h8rs. I'd drive it (just wouldn't pay for it).

 

word. Who needs to pull time at 16psi with no intercooler? I mean ****, it had a 5th injector...lol.

 

It's a nice car, sure, and the torque curve is very good, but it's nothing a turbo can't do for way less money. Sorry if I'm not impressed with a built '99 motor that can only make 220lb.ft of torque at 14psi.

 

Im gonna wait for some more numbers but damn that doesnt 2750 for hardware and charger seems appealing

 

Loki,

I agree. SC's since the mp62 is being used are much more appealing, particularly with pricing under 3K. Sure DIY turbo you can get alot more for the money but for a bolt on ready to go kit with support the pricing doesn't seem that bad. Figure out affordable fueling and tune and it's an option worth considering.

 

$3k is pretty expensive, IMO. The majority of the costs of turboing a Miata are the "fueling and tune" and the rest of the crap that goes along with it. I didn't exactly cheap out on my setup and I spent $1600 on the actual hardware bits. The rest of it was radiator, clutch, exhaust, Megasquirt, gauges, blahblahblahblabhal.

 

but you got a used T25, you need look comparative to a New T25 , there are no used parts from this market yet.

Specially with my MSPNP supercahrger is very appealing. I would need dimensions off the actual hot side assembly.

 

It's at 10psi. And would have a much more usable power band compared to most T25 turbos.

At 14 psi, expect another 25-35 tq.

 

Yeah what he said. I mean your dealing with a worked over head, which is one of the biggest restrictions on a miata. We had a discussion on the gains from a FM ported head already. Sure, the numbers look pretty, but put it on a stock motor and show me those numbers. That will impress me.

 

There's a 20% correction factor on that dyno chart. I'd love to expect another 35tq: 219x80%= 175.2 + 35 = 210.2

Not impressed.

If I had bought a brand-new ball-bearing Garrett, vs. the brand-new oil-journal Garrett I actually did buy, it would have added $750 to the price. $2300 < $2750 and I'd be getting even more spool and more torque. As is, I'm making 200lb.ft 300rpm sooner than that, and that's not even a ball-bearing turbo.

As far as useable powerband, I wish I had my dyno charts scanned into the computer. 200lb.ft at 3000rpm and 180lb.ft at 6000rpm is plenty useable.
