Tired of Carbs want injection, Have 74 1.8L dual webber going to injection Options

This creates flutter inside the plenum which can make the air fuel meter flapper door flutter and give you issues.

Do you know this from experience?
My experience is that the AFM is not negatively affected by a fair amount of overlap.
It's harder to tune the engine because the programmed fuel curve isn't correct for the performance characteristics of a more aggressive camshaft.
Adjustments within the AFM to keep the metered fuel rate correct are limited so additional enrichment may be needed.

Yes, personal experience.

Its why I did Djet.

Thanks for asking though.

First off... (IMG:style_emoticons/default/welcome.png)

There is a small but growing number of us in Austin. We have not gotten together yet
but I think we are interested in doing so.

I don't know much about L-jet but I can still help out.
Where in Austin are you? I am near the Arboretum, others in Georgetown and Pflugerville. LETS GET IT ON!

Near Manchaca Road - would like to trade numbers/email.

Howdy to AusDan,

I am also in South Austin, a few blocks from Manchaca Rd off S 1st St. I'll have to stop by to see your car! Please send PM with ph # if you'd care to visit. (IMG:style_emoticons/default/beerchug.gif)

Betty and I will be in Austin for the PCA club race at COTA. We will be in her 914. How about we arrange a dinner for then?

When and where would you want to meet?

[CatDaddy60]

I'm in Pflugerville and would also like to get together. I have several manuals and a rudimentary knowledge of FI injection systems (I can be dangerous). I would be interested in helping. let me know when and where. I also know a former Porsche master mechanic that just got a lift in his home shop in Spring Branch Tx and what we can't sort I know he would be willing to help.

[CatDaddy60]

Well that was great getting together with ausdan and bobl and talking 914s . I look forward to helping everyone on the Austin area.

Im a huge fan of d jet mine runs almost flawless
When warm

But modern style injection with the sensors and sniffers

I would think will outperform d jet everytime

I like the kits that look like webbers but are actually f.i



And so much cleaner

No big pile of. (IMG:style_emoticons/default/stromberg.gif) on top of the engine

It will start and run with a carb cam, but it runs very shitty!

[cgnj]

I don't know, but it feels as though it has a non-stock cam. As I go though it, I want to return it to stock. I think it has some ticking noise coming from the heads I suspect valve wear. I am getting some excellent as well as reassuring posts to this.

Hi,
Pull the oil pump. Rivets = original cam, bolts = replacement. If it is aftermarket, the part number is usually stamped on the cam. turn motor and write the number down.

Plenty of places will regrind/re-profile a stock geared cam. In fact that's the only way to get the correct size cam gear to match your case that I know of.

L-Jet runs great with a "Mild" carb cam, no experience past that on the "mild to wild" curve...

Betty's car has a Raby 9590 cam in it, and it runs great with the L-Jet.

We will be in Austin on May 6, 7, and 8th for the PCA club race. Our hotel is near where 71 and 183 (Ben White and Riverside) so we can meet at a restaurant near there for dinner on Saturday.

Pretty sure that the 9590 or 9550 from Jake has wider lobes with a faster ramp, but the same overlap. Ljet does not car about that, but djet does at idle.

Really? That would be great. Do not mean to hi-jack, but I also have a '74 1.8. I built a 1911cc with Webers, but I too want to put the L-Jet on it. I like the extra power of the 1911, but prefer the L-Jet smoothness.

Is overlap the critical factor with this cam and L-Jet?

That cam is working fine in the Wife's 914 with L-Jet. She loves the extra power.....
