New head

[baltobernie]

you would be shocked at the results that a good exhaust system will provide on top of what you've already done

Groan! But there's that new top, and wood steering wheel, and ...

Maybe after I get tired of the "Flowmaster Sound"

[baltobernie]

Don't forget, you offered me a test drive!

It's a shame you won't be here on Sunday; the route we've laid out is terrific. A bit of the twisty bits like your DixieFest wooded section, and lots of rolling farmland, too. You still thinking of coming up for the October car show? It's quite a haul from W/S, I know, but maybe if I had your spunk I could arrange a similar venue next Autumn.

I'm a little supprised, I would have thought you would get more than 125hp with all those mods. By the way, the top is down 90 percent of the time and the sound from a good exhaust will make you smile and bring more satisfaction than a shinny wood steering wheel.

Hi !

I have finally got a dyno test on my car. I was a little surprised that the HP wasnt better, but the toque is good.
All the numbers are " on the wheels", after the loss in the driveline.
My friend whos has build the engine will look at the numbers , and find out hwat we have to do to get more HP. It really should have been some more. But the torque is good






PS. not sure if I have got the pictures right, but you can see them at my homesite

If I understood your car history correctly you have a 2L head on a 1800 engine. If this is so, even after surfacing your compression would be low. Just a thought...

Hi!

I have a 2,0 l Strada 130 TC engine with these spec:

* New Abarth 130TC big valve head, upgraded new billet fast road inlet cam with 10.65 lift, original 1608 exhaust cam, rejetted 40 IDFs with 34 chokes and new Ram Pipes

* My friend have build a new 2 liter engine and put the 130TC head on it. here is the spec:

10:1+ pistons
130 TC head - 36 mm parallel intake - 34 mm exhaust + valve + guide + seat mods
44 IDF - 36 chokes, F16, 145 mains, 180 air
Inlet cam billet - 10.45 true lift, 280 degrees, 2.5 lift TDC - timed 110
Exhaust cam 1608 - used but still OK I suppose (9.3 lift on lobes) - timed 110
Exhaust manifold 4-2 cast iron into 2-1 secondary pipes - (standard 1800 sport) - 2 " free flow system from manifold and back

Congratulations on getting your engine sorted out. Yes, professional tuners can really make a difference, much as us amateurs hate to admit it

Looks like you've got it "dialed in" for everyday use, with torque peak at 60 mph in 5th. No downshifting required, eh?

[FMO]

Thanks .
does anyone know how much the power loss in drivetrain/transmission is in a Spider ( approx)

regards FMO

[baltobernie]

About 20 HP, according to a Mazda Miata builder/tuner/racer that tested my car. He has chassis dyno'd engines fresh from an engine dyno, and says that on his setup, he sees a 20% loss difference. So 104 RWHP equates to about 125 SAE net.

[FMO]

Thanks again!

A bit strange , its a tuned Strada/Ritmo 130 TC engine, with originally 130HP, so it really should have been a bit more.
Well at least the torque is higher then the original , he he. My engine builder will look at the numbers , maybe we will put the intake cam to exhaust and get an another intake cam. Then take a new dyno test.

Lol., reading this, I? have to add my own funny story. Blew the enging last summer (about a month after I got it...).

Bought a rebuilt engine from a supplier in another city, and had a mechanic who 1)had never seen a Fiat and 2)gave me great rates install the engine.

Was a little dissapointed by the lack of zoom, and the still rough idle... Last weekend, while waiting for my girlfriend to get ready, I poked around under the hood... Lo! there were some sort of electric clips going to the Injectors, but only 3 were plugged in! The fourth has a slightly mangled clip...

Unsure if/when it got disconnected, but MUCH happier with the zoom out of my sweet car NOW!!!

Going to drop it at a mechanic who used to specialize in Fiats to dial in the idle, etc. Will still use the other mech for brakes, etc...
