First install

[Elphaba]

:sweatdrop: How goes it? :sweatdrop:

[Tom @ Fast Forward]

I think Bill will turn the key today. :party:

[Steve in VC]

When is the dyno run scheduled? :biggrin:

[Tom @ Fast Forward]

He will figure that out after he turns the key. Which, as I understand , is happening now.

The 1.6L Coldside is born at 4:11pm 01-24-10 MST.

Cigars all around!

BEAUTIFUL!!!

I've been looking for a coldside M62 for my 1.6L and this is it :)


Awesome work you guys. I used to work at a place in Houston that used a coldside M45 kit of yours on our Ginetta G20 kit car :)

It drove nice :)

[Elphaba]

:taz: Oh my God ! He put it on the WRONG side ! :rofl::rofl: Seriously. I cant wait to see this one on the dyno at Keiths place. Will you find a way to get the AFM away from the header?

[FormerDatsun510Man]

The stock airbox is in place merely for running it and we are waiting for a cone filter and hardware. I expect to keep the AFM in the corner behind the driver side headlight though. That is the coolest location under the hood, especially if you pop up the headlight or install NACA ducts. This is also the best location for a CAI, which we intend to have (hint hint Ari :biggrin:) soon!

:devil2:WOOF !! :devil2: Me like'e !!

[KirkJ]

:drool5: Any dyno details yet?

[Tom @ Fast Forward]

Well, here's the scoop. it ran for about 5 minutes idling on 4 jack stands. Then, poof. The end of the crank broke. Turns out the previous owner had the timing belt splined pulley off and, when re-installing it, did it wrong. The key slipped forward and, when he tightened the bolt, it was a good half inch short of seating. As we don't mess with that, we never noticed. To make a long story short, we have to replace the crank. We have pulled the engine, removed the old crank and have replaced it and the engine is going back in today.

We debated whether to used the "good" crank or the "90/91 small crank" again like original. The engineer in me wanted real bad to replace with the stronger crank. However, the customer side of me won and a stock 1990 crank is going back. We want to assure all that the crank was not a problem and is not at fault. It was operator error on the part of some previous owner.

We have two customers here for install and dyno work so it is not likely to happen today. We should have it back on the road Monday at the latest. As the dyno is closed Mondays, it will be Tuesday at the earliest before it gets strapped down. Sorry for the delay.

Those of you with 90/91 small nose cranks should probably inspect them to ensure nobody over the life of the car has screwed up. That bolt need to go that extra 1/2" into the heart of the crank as that is what helps stiffen the transition at the front seal. Just a minor set back.

I'd hate to see a major setback... :devil:

[Tom @ Fast Forward]

What's a crank among friends? :)

[BlownMX5]

You did the right thing using the smallnose crank. If assembled properly, it shouldn't be a problem. Checking the key on any 90-91 crank is always a good idea.

[Tom @ Fast Forward]

I wouldn't have felt right if I tested on the big crank and then told you it was fine on the small crank. Although that big nose crank looks great and fits all my stock crank pulleys. All I have, at the momen, for the small nose is 105mm. However, we think the 105mm "might" be enough as Bill thinks it "might" push 190.

As it is only 85-90 typical, I thought 170/180 (100% increase) might be OK? :)

[Elphaba]

:eek: CRAP :eek: Sorry to here that Tom. Ive never heard of a 1.6 being cantankerous during development. :rofl: Better to catch it at idle than at 7000 rpm on the dyno. Give me a call Monday or so I think Im off Tue and Wed. I'd LOVE to see and here that one on the dyno.

[Tom @ Fast Forward]

Easier for you to call me if you are free. I am up in Chandler these days. :)

[KirkJ]

Sorry to hear about all the issues but I guess any great projects will have some setbacks.

I'm half way through replacing my timing belt as we speak so I'll make sure everything is ready and working properly for supercharged goodness :)

[Tom @ Fast Forward]

I honestly think all the "small crank" problems that have been written up on mnet are operator error one way or the other. We will prove that our kit will run, make a LOT of power and last a long time on the small crank.

"Getting CARB is extremely hard" but we did it.
"You can't make 200+ WHP without an intercooler" but we did it.

The DIFFICULT is done at once; the impossible takes a little longer. :) we like to do the impossible here. One of my favorite poems (ECool, anyone? :)) by Edgar Guest:

Somebody said that it couldn't be done,
But, he (sic FFS :)) with a chuckle replied
That "maybe it couldn't" but he would be one
Who wouldn't say so till he'd tried.

So he buckled right in with the trace of a grin
On his face. If he worried he hid it.
He started to sing as he tackled the thing
That couldn't be done, as he did it.

Somebody scoffed: "Oh, you'll never do that;
At least no one we know has done it";
But he took off his coat and he took off his hat,
And the first thing we knew he'd begun it.

With a lift of his chin and a bit of a grin,
Without any doubting or quiddit,
He started to sing as he tackled the thing
That couldn't be done, and he did it.

There are thousands to tell you it cannot be done,
There are thousands to prophesy failure;
There are thousands to point out to you, one by one,
The dangers that wait to assail you.

But just buckle right in with a bit of a grin,
Just take off your coat and go to it;
Just start to sing as you tackle the thing
That cannot be done, and you'll do it .

Did the keyway have a "v" shape to it when you removed the pulley? I ask, because my first Miata, a 92 (long crank) nearly failed outright. The car had just shy of 100k on the clock and the water pump was leaking. It had the worst lifter noise you'd ever heard as well. Long story short, I take it to the Miata shop here in Northern VA (PBC) and he found the keyway was not straight, but was angled out on one side. This caused pulley wobble which was the "lifter noise" I heard. Cure? Motor out of a 93. The wrench suspected the Mazda dealer who did the timing belt at 60k may have put the key in backwards somehow and forced the pulley on.

[Tom @ Fast Forward]

I will take pictures of the parts but, I believe the keyway was straight and true. The person effecting the repair somewhere in the car's history simply did not install the key correctly when re-assembling. It is obvious when you look at it. The engine ran so well, we did not want to simply replace it, so, in goes the new/used crank.

[Steve in VC]

It was operator error on the part of some previous owner.This is the attention to detail that your customers really appreciate.

No "one off's".

Of course, I would enjoy the supercharger install instructions.

1. Remove engine, replace crank with long nose crank, replace engine.....

[Elphaba]

Meh... I've been living with ~170hp on a "short nose" for quite some time now with no problems. Perhaps: #1 check keyway #2 do timing belt change correctly # 3 install coldside kit #4 turn key and enjoy:biggrin:

[Tom @ Fast Forward]

Elphaba has the correct answer. His kit is exactly the same as the Coldside. It is simply misplaced in the engine compartment.

The 90 will be running at High Noon today. :party:

[Elphaba]

DOH!! Iwant mi ne on the right side;)

[Tom @ Fast Forward]

What??? Are you blaming me? :hammer:

Your days are numbered.

[Steve in VC]

What??? Are you blaming me? :hammer:

Your days are numbered.Who else does he blame, you and Bill have been waving a red flag (actually a red Miata) in front of a (HP) bull. :)

Marketing is "demand creation", yours is obviously working.

How is it running?

[Tom @ Fast Forward]

OK, it runs. I left Bill a few minutes ago installing the 4 EGT thermocouples. Testing will start today.

here is a picture of the broken part. You can see the key sticking out and jammed against the bolt flange. It sheared right at the end of the bolt which also was the part of the shaft sticking out of the crank. Had the bolt been properly seated, this would not have happened. GRRRRR

[KirkJ]

Dare we ask.... any success on the dyno yet?

[Tom @ Fast Forward]

We are getting close.

[Elphaba]

:sweatdrop: How CCCCCCClose :sweatdrop: Need a fix man :ack2:

[Tom @ Fast Forward]

Runs Great. Has a tuning hiccup as it passes through 0PSI but after that, hold on. ;)

[Steve in VC]

Runs Great. Has a tuning hiccup as it passes through 0PSI but after that, hold on. ;)Sell him a kit. You'll have the bug worked out by the time he has it installed (maybe not - I suspect he will pull an all nighter).

Also, he is right in the neighborhood and can give you a second system to identify bugs your car doesn't have.

[Tom @ Fast Forward]

LOL. I already did. That's my 1.6L Hotside he's sporting. :)

[Steve in VC]

:sweatdrop: How CCCCCCClose :sweatdrop: Need a fix man :ack2:Are you going to put a SC on both sides of the engine? I want to see your belt arrangement.

[Elphaba]

:eek::eek: Steve! your a genius! :biggrin:

[Steve in VC]

:eek::eek: Steve! your a genius! :biggrin:Hook them in series or parallel? Series, with an intercooler between hotside and coldside. More power than Big Gulp in a 1.6!

[Elphaba]

Well. Is their dyno time coming up

[Tom @ Fast Forward]

Well, first pass was only 141WHP. LOL. Anyhow, first pass was 173WHP. We have found 2 problems. First, and foremost, the TPS adaptor has a design problem. We redesigned it over the weekend and the shop will turn them out in the next day or two. Second is the remote IAC plate. I redesigned it back when I modified yours but we never made them. I grabbed one and was forced to relearn history. It too is now being made anew at the shop. Should have new parts in a couple days. If this was easy, others would make them too. ;-) This IS what everybody has been waiting for. +80WHP and stock drivability on 91 octane and, bonus, CARB.

[Buck Reynolds]

Good work Tom

[richie01_1963]

Board has not had any updates in some time now
Good work Tom

[FormerDatsun510Man]

We are in the process of changing out to the production manifold. Should be complete by later this week. Then we have some more tests to run to be sure it is 100%.

[richie01_1963]

Uncle Sam is buying me a SC for my 1.6 Sunburst!! LOL

[Tom @ Fast Forward]

take what you can when you can. Uncky Sam isn't going to have any money much longer.

[Elphaba]

:devil: Its "later this week" :devil: Update? Im in the same boat as richie ( sort of ) Itching for some coldside goodness. Dont worry Tom. If Uncle runs out of money he'll just add a 4th shift on at the printing presses...

[Tom @ Fast Forward]

I should have the new parts this weekend. I'm guessing Monday/Tuesday should be the day.

[richie01_1963]

If the Fed had a cold side on the printing press that they use to do the legal counterfeiting ?? They would be printing greenbacks like crazy!!
