Lol yes just a bit! In that case I maintain my original recommendation, and I'd be tempted to go straight in for the kill with a 500lb rear spring.
What is the actual issue your suffering or experiencing Sam? Apologies I've only skim read :S
Scrap fitting the angled spacers. They're all SF flange but the ktec dth bodies are what looks like dcoe where the trumpet bolts on. You can possibly buy adapters, but f**k that for a laugh. It'd cost a fookin fortune.
My kw's have 330lb front springs as standard and they're a bit too soft for track work as it allows the front end to roll over itself a bit, but on the back road lanes near me it's very composed. I'd be very tempted to up the fronts to only 350lb.
So am I correct in understanding that you have...
Magnet is old hat now dan!! Lol! The latest way they do it is to have a box of tricks in between the digi tacho head to interrupt the wiring, and at the press of a button on a remote control fob your limiter less. The other way is to send your digi head to a place in Europe that puts a microchip...
As fast as it would be with a trailer mate! They're speed limited to 89km/h. Unless your Irish of course. They get special 'unlimited' models. All at the flick of a switch!!! ;)
I've always done the exhaust ports with an 80 grit finish Chip, which leaves them nice and smooth as I'm sure your aware. I just don't see any point in mirror polishing the exhaust ports. For the amount of effort you have to put in to get that finish, the gains in performance aren't warranted...
Yeah looks alright to me mate. The guy who taught me told me not to bother. He's a well respected tuner in ford circles as well, so I trust his opinion.
At 300 you'll be fine mate. It would probably only knock a couple of psi off the boost level as well if you opened them out. Have you got experience of porting cylinder heads? If you haven't mate I'd leave it personally or take it to someone that has.
Yes you can open them out to ph1 size mate. In fact you can go significantly larger than ph1 if you want but it's a bit pointless. It's all in the shape of the ports not how big they are mate. What hp are you looking for? Original ph2 head flows fine in boosted applications anyway (up to a point...
The way I see it is you've got 4 options:
1) buy the ktec dth bodies and accept its restrictions/limitations
2) buy the ktec dth bodies and use the angle spacers that you can buy off Jenvey so you can run different length trumpets and *possibly* have no air filter packaging issues
3) buy the...
yeah mines a hero3. I thought they did them for the 2 tbh. Your only option after that is to drill the side of the casing if you can't find a frame mount.
They're set soft as the ring is quite a bumpy circuit to race on. Anywhere between 450-550 should work well for you, but it all comes down to the damping rates. You'd need good rebound settings.
