Absolutely, glad it meets with your approval Gary, but what's that I spy ?, a standard coil & distributor ? but surely that won't work, or perhaps it will

Thing is Richard, Pete built that well before aftermarket ECUs were commonly on Tivs as you'd be aware had you been around the Northampton branch of the TVRCC in the early 2000s when he was a regular in the car. I'd certainly be interested to know what he's running now; I suspect it might not involve a clockwork distributor. Maybe he'll enlighten us if he spots this; then you can tell him how he's got it all wrong

Last I heard it was on megasquirt but i've not spoken to peter for about a year.

For me Peter was a mine of information and sounded a gentleman. I recall he got shot down a few times by the lesser informed and must've got pissed off with it. I miss his input around here.

Absolutely; would be great to see him return if he's around.

I apologise for my ignorance, still a bit too green. I'll keep my mouth shut until I've got my installation done, then I'll have some experience to base my comments on. No offence meant.

Sorry Richard, not directly at you and I look forward to reading about your conversion. It's an observation and a shame that he [and some others] are absent from these forums as of late and I recall couple of posts with some pub talking keyboard warriors who knew FA, shouting him down when all he was doing was passing on his knowledge on given subjects. Some have it in their heads that they know best, when they actually don't and make no room to considfer the opinions of others. Shame really.

Suffice to say that my suggestion that a standard distributor & coil shouldn't work was a sarcastic one. I'm still intending to stick with the Lucas set up initially when supercharged, my comment was aimed at those who insist it won't work, even though they haven't tried it. However there seems to be several out there that do !
I sincerely wish I had been around in this environment when Peter was putting together a "proper" supercharger from scratch, it certainly looks very impressive and I can only admire the determination and skill in undertaking such a project, far more balls than me (and I suspect most).

You've nothing to apologise for Richard, you were just having a bit of a laugh and anyone with half a sense of humour could see that.
I enjoy all the wit, banter and the odd bottom joke, however I do agree with Mac though there are a lot of people absent from these forums who used to give freely of their own time and expertise but then got fed up of shouty sorts who used to challenge them at every opportunity. The forum is a poorer place without them.

I had a quick look at the Torqueflow turbo set up. He was running a stock dizzy- there is some way of frigging it mechanically to give the correct advance under boost, but its very crude as I understand it. The Aldon Amethyst will allow you to map the ignition with boost, id say its the least you require if sticking with the 14CUX.

[spitfire4v8]

When I spoke to Eann at the growl last year he said that positive pressure into the vac advance unit on his car brought an element of retard into the total timing. You used to be able to get proper boost retard vacuum advance units .. seems some RV8s might already have a vac unit that will give some retard if pressure-fed.
But I agree with blitz ^^ if you want peace of mind you really need to be able to map your timing on boost properly ..

Really not sure what to make of this. The 'sarcasm' (do you really mean 'irony'?) was aimed at me but, as far as I recall, I have never insisted either on here or in person that the stock system cannot be made to work; it obviously works well enough for some. In fact I remember specifically saying to you at Sywell that I thought the fuel would/could be fine but that a mappable ignition would be a better idea if you wanted to keep the 14CUX ECU (for exactly the reasons mark and Jools have separately confirmed). That was after you sought me out and asked my views upon learning I was doing a homebrew FI installation (not a kit), and that view was informed by my having used various Adams' mapped 14CUXs, and having since moved to Emerald for fuel and ignition (on NA). Frankly mate, if you are likely not to approve of the answer, probably best you don't ask the question.

You can run a holley carbed stock 4.6 with a boost retard unit and it'll be plenty 'boost enough' off idle. It'll easily match a supercharged engine. You don't need to make these projects expensive or complex to have fun. People were running reliable turbocharged rover engines 20 years ago. I used a mallory unilite on my engine and a mechanical holley 450. It was quick, I never met a match on the street. Then I got a motec 3d ecu. I faffed about with that and sure, it had benefits but in reality, I preferred the carb and a boost retard unit. Twiddling about with a screwdriver is much simpler then producing 3D maps and more fun on a sunday afternoon

Like Boosted LS wrote.. it´s not very complicated, the problems usually comes when the boost is very high.
My setup is a Mallory Unilite with connected vacuum controlled by the MSD Boost controller box.
No mods to the springs and the weights inside the Unilite diz. It was the famous "plug N Play"

The carb is the standard Holley 4150 600cfm DP, with a some epoxi in all the holes that make the boost leak.
The Holley is fed by twin Mitsubishi TD04HL-15T #5 turbos from the Saab 95 Aero (250 HP)

The boost is for the moment the lowest possible 4PSI. The pressure side of the turbos is directly connected to the actuators.
Works like a charm! huge torque and the power is approx 350- 400hp in a lightly tuned 4.6!!
Absolutley NO LAG NO LAG AT ALL!!

Ported heads, standard valves, uprated double valve springs, 9:35:1 CR, Standard pistons, standard crank and rods,
ARP bolts in the bottom and the top. MSD Blaster ll coil, Boost performance exhaust manifolds, The BOV is a Greddy type S.. and NO intercooler

My headgaskets have been a problem. I will upgrade to Cometic MLS. The composites blew out. Probably because i have not mapped the engine 100% perfect yet. And i got some minor problems with boost spikes... Some sort of quality boost controller is on the list to the next season

Gary, definitely NOT aimed at you but elsewhere & I apologise if that's the way it read to you. I also apologise for my poor use of the English language, I very much do appreciate the advice you have given me and remain seriously impressed with all the work, effort and determination you have and continue to put in developing and building your own system, mine will only be a kit that will not have the unique nature of yours (that is a compliment).
However I do have to say that I have also had a great deal of positive and useful information, which I very much appreciate, from others PH'ers who have already gone down the FI route.

Once again I apologise for any offence caused and this time will really keep my gob shut until I have something worthy of comment.

Thankyou ALL.

Guys, guys, we're all here to help each other and learn from each other
Looking forward to meeting up at some event with a row of FI TVR's to admire and sink a couple, eh?

Zoddy, show these guys what a carbed engine with a dizzy can do, they've really got no idea.

Well, Maybe I can upload a short clip to show how my car work.. Of course It won´t be possible to give you the reel feel of it, the punch is more than twice than any film can show you. Nothing on the engine is fully optimal, the exhaust plumbing, the map and so on.. but it still pulls like a demon.. I´ve been reading in forums for a very long time and all i can read is how much problems and how impossible everything is to make a turbo engine work, mostly from ppl that don´t have a clue and tried turbo before.
IMO it´s just B.S as long as the boost is kept under 1 bar. Start at low boost, climb up slowly and solve the problems that might occur

Before I even started the engine I doubt that i would feel any extra power from the tiny 4PSI. But i can promise you that it was a jaw dropping moment! Even one of my friends that asked me for a test run, He have his whole garage full of bigblock corvettes and he is used to powerful cars and he yelled... "I DIDN`T EXPECT THAT!!" Damn.. I can´t keep up with you!! I need turbos too!!

I´m far from a "turbo" expert but i have noticed that the amount of air from the turbos is very important, not only the pressure.
The Saab TD04-15T is a perfect match for my 4.6, and it works really good on the 3.5 too
The Saab 95 Aero engine is a 2,3 liter and this is the half of the RV8 4.6..

Here is the clip, i uploaded it to a clouddrive. Here is what you will see..

The trip is filmed with a s.h.i.t.t.y iPhone and it´s in some industrial area in my town.
The first run is a bit slippery and the wheels spinning out of control because of some gravel,
that´s why it´s little bit slow.

Then I´m turning back and out to the public road to get rid of all the dirt and then I floor it again.
Note the total lack of boostlag and how the grip is improving. Hard to keep the camera steady..
And...No missfire, no stumble and so on..

My passenger with the excitement in his voice is my friends kid, and his phone battery suddenly dies,
but it will still give you an idea what 4PSI does to the 4.6 with a 99%
Standard BLOW THRU CARB setup!! and the 100% Standard Unlilite dizzy!

The car is not super light! At that day the total weight was apporox 1400kg
and the glowing red light in the window is just a faulty oil pressure sensor
that been damaged of the hot exhaust housing on the turbo so no worry about that

Ok enough bla bla.. check it out!
