Jesus you know how to make my head hurt in the morning don't you:d Surely if the exhaust and inlet valves are stock size a re-shim wouldn't need to happend? I would of thought less?... Yes agreed intertia may be an issue.. but i'd of thoght a stock rpm limit would be more adequate?

Can anyway enlighten me what the benefits of uprated exhaust (standard size) and inlet valves are over OEM stock ones?

Is there much head work needed for these to drop in... I could be very interested..... pm me.

Did you have an interesting drive home with Nick? and who was faster?

Surely using language like that is a sign of immaturity... Just post some pics up or as Jay said the e-bay lisiting. Then us a community could help you out more.

i wonder why your wanting this then

I guess this guy could be a 21 yr old Dreamer!!! Please prove me wrong... Mod's i think we somehow need to check out this guy is genuine?

The only reason i noticed this was purely down to my egt gauge... the car runs spot on apart from that.... starts well, idles, well performs very well on full load and off boost.... no smoking...... Looking extensivly at the pistons, crowns etc.. everything is spot on... all cylinders apart from no 2 on leakdown are fine... So its very mysterious and can't explain it! Its a good excuse to take the head off anyway to do some polishing etc etc...so im not that gutted really.

"No"

Will do.. going to get onto it in the next week or so.. and get it done ready for JAE.

Well so i've been told? and what the spec says.. but we will see...

Yes its had head work done to it before... a month back, the compression was fine ona all cylinders....

it has titanium springs... What could cause this issue? lean mapping?

Im afriad i had a very unentertaining visit to the Dyno today... on the way over i noticed my Egt's were very high i.e on a 3rpm cruise 800 deg and WOT runs around 960 deg which i was a little uneasy with.. Did a compression test 1. 160 2. 75 but with an extra 3 pumps 125 3. 160 4. 160 5.155 6.160 Looked at the piston crowns and bores with the boroscope and all looked all ok. Did a cycliner leakdown test, no 2 40% and you could hear the hissing through the back on the exhaust.. So new exhaust valves and cylinder head skimmed i guess... May as well do the Valve stem seals as well well im at it.. Whilst the head us off, is it worth doing anything else?

Well ive got the software on my laptop and yes it does have a huge range of functions and is certainly the Budget option of some of 5h3 MOTEC ecu's...(and has nearly about as many features as the MOTEC ecu... Speaking to Dan about some of its features, he does seem clued up about what the ECU can provide....

There could be a seperate thread raised here, whats most safest, a wet or dry nitrous kit..... I know the wet kits tend to be more affective, but they tend to be more prone to failure (i.e fuel solonoid failure) where dry kits rely's on fuel pressure... I do agree with Homer's comments that it is down to the mapper on doing a good fuel/ignition correction mapon nitrous activation.. the ideal would be to have contstant ideal bottle pressure (i.e bottle electric blanket to maintain the ideal pressure) and a map to suit nitrous activation

What made you want to swop mate!!!???!!?!?!? Surely your single was allot faster than would the scooby would be.

Please quote me if im wrong guys!!! But surely nitrous pressure can be variant if the bottle does not get up to pressure.. So you are taking a gamble to a degree if the bottle is not up to pressure.. hence the need for an accurate nitrous pressure gauge!! So getting the perfect fuel/nitrous mix can be very hard to do especially with are very changing weather conditons. Of course the ideal would be an ecu that could control the nitrous/fuel supply, with reading a nitrous pressure sensor...

Going on Jamies Point, in the warmer weather nitrous will tend to work allot better than it would in the winter due it reaching its optimum bottle pressure (nitrous bottle getting to temperature).

Im not sure on how Dean Turbo Boost was controlled either? was it EBC or did the AEM control it?

Its a tough call, I had an N20 Car that i ran nitrous on and it was very difficult to keep maintained steady boost as nitrous does make boost harder to control and set during different ambient temperature conditions....

Come on guys, give the guy a break.. .Nitrous does tend to spike boost as we all know... So i can see Dan's argument in raising the boost for mapping.. its a very difficult one to Judge... We all know there is huge risk in tuning an engine especially with nitrous!!! So a map with 1.5 bar could easily spike to 1.7 bar on a nitrous run??

Thats an excellent result, well done you guys!!!! im droppin mine off later today for its final map and one or two extras!!! Dan's a great guy and i've nothing but praise for him!!! :D

Expensive hobby!

1200hp!! why do u need that much?
