Got Car Back Tonight

[portaz]

Hi guys got my car back tonight with a cruise tune of almost 240kw at 11 psi, I have a very slight leak I have to rectify around #3 inlet manifold hopefully simple. Anyway with the adaptronic 1280 and Bosch 2200 injectors I was suprised how smooth it was especially for quick tune . This ecu is crazy and has everything even launch control and almost anything it's completely programable in every way.

Thanks to jez and Andy btw, but we were talking and I really want 400 kw plus on e 85 so we decided to put cams and possibly springs , it's a forged engine std stroke with mild porting in cylinder head and exh manifolds. So do I just go the usual type b as jez said they are proven or try a custom grind still with full size base circle but 10 mm lift or more? And say 260 duration to keep power band low? I don't want to change shims as right now it's perfect and super quiet all I can hear Is injectors. It also has hks adjustable cam gears , we can change them out in about 2 hours but I just want to give it best chance offline the power, car will be used for drags and hill climbs etc not much circuit. I have researched around 6 hours on this subject but posts go back to 2009 so if there is a thread please direct me to it.

You don't say what engine you have but have you read the 400kw thread? Right turbo(s) more important than cams at that level.

[portaz]

Rb26 and yes read rb26 thread and 400 kw thread but it goes off topic and is not a very good information source

Chuck a HTA 3582 on the side of it and have epic response AND power.... I replaced my GT3037 with a HTA3076 (same size turbo) and made 391kw and super response!! The car is totally different now and just the way I want it!!!

[portaz]

I want to stay twins but I know it's heaps easier to make the power with a single It looks like I will go a camtech grind 272 , 9.75mm lift depending on my clearance measurements on stock cams or I may get him to reduce duration a bit

Give Unigroup a call. They will have something that interests you.

Guys Scott has been discussing his car over a couple of threads, the setup is done... No need to discuss alternate turbo options etc. Just cams.

Having only done a little research I am with Jez on the Tomei type B's. You don't need anything too massive to hit your targets, and a tried and tested combo seems like a safer option than trying a custom combo.

[Joshbigt62r]

Go with the tomei type b cams Scott. Can't go wrong and are good for WELL over 400kw.

[portaz]

Ok that is easy Option which actually I dont mind will they need springs ? Debate seems to be out over many topics, thanks guys I really appreciate replies

[SiR_RB]

You can get away with stock springs with poncams, but upgraded springs would be good, super tech springs

[DVS JEZ]

Correct. Its recommended but not required

[GTScotT]

RBs are a sad story when it comes to valve springs IMO.

Do em while your on the job and guarantee yourself the results

[SiR_RB]

And check you valve clearance ! Might need to swap some shims around and or new shims to get it spot on

[portaz]

Can't deal with new shims lol I think it "should be ok in theory as the valve seat and valve govern the distance and shim required and supposedly with 32mm base circle all should be well, supertech do a dual spring with 92lbs seat pressure is that overkill ? Can u go too far with springs ? And sir rb those cams I had were 29 mm base circle hence the dramas but I should have run thicker buckets to compensate, it's good cause u don't need relief but bad cause of mucking around

[Piggaz]

Duel springs for poncams? DEFINATELY!!!

You'd be crazy not to to Atleast check clearances and adjust accordingly! Do it right the first time!

[portaz]

Oh I will check them and get jez to double check them I'm just hoping the theory is they are ok as we don't need more down time, so duals are ok then I hate the extra seat pressure to snap the end of a valve off or something

[Piggaz]

Sorry, you took my definately the wrong way. Definately overkill! Lol

[r32-25t]

Best advise anyone in this thread can give, listen to jez he knows what his talking about

[portaz]

Yep just asked him all soughted thanks guys

[luke gtr]

valve springs will be 20yrs old.

more boost, high rpm, do the springs while its apart.

just a decent single spring.

and new cams will still need shimming.

even with the same base circle, shims are .05mm iirc, sfa in it, and I dont see machining/casting being that spot on.
