Worth a gamble or not?

Picked up the car today, Dave has done an awesome job. The old leather has come up brilliantly, it’s really a great result. Hood colour etc, spot on.
Now off to Jules to work his magic.
Emerald/wide band/3 maps
Bigger Injectors
Pre-cats out
72mm plenum
More power/torque/noise and better manners.
Be interesting to see what numbers you get. Joo transformed our Griff. Now off to Jules to work his magic.

I’m just blown away by the craftsmanship today. In the UK we are surrounded by people who are genuinely interested in making magnificent things from challenges. I was watching them today with a steamer, on a seat base. I wasn’t sure why they were doing it so asked. Apparently when you stitch across the patten it slightly distorts it. So they steam it to put it exactly straight. That’s attention to detail and it’s awesome. IIRC it was running 300HP with 350ft/lb, from around 1800 rpm on John’s dyno after break in. It’s a fully built 5.2 with a bit of porting and soft cam. I’m not going for top end but I’m looking forward to no shunting! Had lots of pinking on the Lucas setup, always felt a little off. It never not started and idled kind of ok, but was variable. Today it ran like a dream, solid 900 rpm no floating. Last time it was hunting, it’s just time to bin the OE kit. Originality is fantastic, but I don’t want a phone call from a pissed off OH that it won’t start etc.
I’m sticking with the plenum as it’s far easier to setup and there are loads of JE 5.2’s making frankly daft numbers without TB’s. It’s already very fit and way more engine than it needs really, but since when did we not want more
It’ll take a load more power than it’ll make, I made sure to spec it so that it was very future proof. Edited by anonymous-user on Tuesday 27th August 21:10
So, working from home and bored. Spoke to Joolz earlier and the car is already coming along, loom is almost there.
Ordered the trumpets as I know there are sone gains from the matched ports. I don't care much for the carbon but it's not much more expensive. Should be the final piece in the plenum upgrade path.

So first words back from Jules and it’s a good set of numbers. The plan was never to chase them as it’s not that sort of car. The cam was specifically chosen for driveability, but the potential was there (cross bolted, top hatted, steel rods etc) should the next owner feel the need to reach 370-400HP 
After running in it did 290HP/336lbs/ft on John Eales’s dyno. I remembered him saying it was a nice build and that he was pleased with the torque spread. I had nothing to compare it to so was happy enough Even taking into account the pessimist JE dyno I’m impressed so far. John said with a better induction setup and modern ecu it would release a good chunk.
From there we added the smooth inlet pipe, blended plenum base and carbon trumpets along with the enlarged plenum inlet. Larger injectors and emerald with wide band welded into the Clive F Y piece. Standard manifolds have had the pre-cats removed.
Looks like a pain in the rear end wiring issue remains, but that’s next!
Waiting now for the final info, but so far it looks pretty awesome.

Why the carbon trumpets rather than a blended base?
Good to see Joo using traditional TVR loom building methods
The base is the ACT one, I went with carbon purely because it was available off the shelf. The base is still blended, as I understand it, but instead of spun alloy trumpets, carbon ones are bonded in. They claim 10ftlb and 8-10HP, I can't say if this is true but the numbers today are very good indeed. Good to see Joo using traditional TVR loom building methods
What's not in doubt is that the standad TVR item is like the challenging ginger mate that the best looking girl in school had
Picking up the car tomorrow, slightly apprehensive but I’ll get over it. No rain (fingers crossed) so the ancient T1R’s should be fine
Really looking forward to meeting Joolz and seeing what the ecu has done. Previously it was obvious that it was a bit all over the place, I was super careful with WOT running in as it just pinked too much for my liking.
Clear the garage. It’s coming home!

That is a very impressive result. BHP headline figure great but more importantly that torque! Nice and flat as well.
I must say you have done an incredible job with this car, it looks absolutely stunning and is a credit to you.
MAKE SURE YOU GET THOSE TYRES CHANGED! When I bought mine it had the original Bridgestone S01 tyres from the factory 15+ years old. It was a death trap and it did not have anywhere near the power of yours.

Thanks Matthew, I’m really keen to see what yours does, it looks like an epic build. I must say you have done an incredible job with this car, it looks absolutely stunning and is a credit to you.

I’ll be really taking it easy tomorrow, the plus points are it’s got a very linear spread. I’ll soon change the tyres, but I was adamant I wouldn’t fit nice tyres for the dyno! The fronts are actually off the Atom, so only 4 years old, erm, yes.
Just got to decide on R888R ot AD08?

Ditto the tyres. My last Chimaera had 16 year old rear tyres when I bought it and was lethal (even in the dry) until I put new ones on.
Impressive results, you have the power of a Cerbera in a Griffith body. Great stuff.
I’m very pleased with it. John has really made a really nice road engine. It might even give a bit more as it’s still only 600 miles or so old .Impressive results, you have the power of a Cerbera in a Griffith body. Great stuff.
Well, it’s back.
If you’re considering an ecu swap, I’d say do it. Totally builds on the strengths and no downsides at all.
The torque between 2-4K is utterly addictive. It’s now got a much harder delivery when provoked, but it still cruises perfectly well. The full de-cat is obviously louder, on the edge of what’s acceptable if you’re going to do longer journeys. Without the crappy advance issues of before it just gives lots of power and doesn’t ease up. It’s not silly fast but it’d surprise a lot of newer cars, it’s the torque but this new edge at the top. Really nice engine.
Not once did I think of the bills driving back. It’s just an icon, more a British Cobra now, than ever before in my eyes. Steers well enough, didn’t do anything daft, feels decent. I’m sure it’d punish you though, if you were hamfisted?
Joolz is a really decent chap. He’s gone beyond what we agreed and didn’t bill me for some really PITA things. He also changed some bushes, which through his experience don’t like the heat much. I thoroughly recommend him.
Lastly, pops and bangs. Very childish, but works for me! Time to get some miles in. (But the OH has already nicked it for a drive)
