barneybrendan Posted April 19, 2010 Author Share Posted April 19, 2010 just orderd the map 2 IAT sensor and harness from the company direct.not too bad worked out £68 deliverd,still a bummer when interpro should of fitted it or at least gave it to me,so nobody go there they are THIEVES.

barneybrendan Posted April 21, 2010 Author Share Posted April 21, 2010 havnt really touched the car for a couple days needed some time away from it to chill out a bit. cracked on today the supercharger side of the engine is now all bolted together.All the wirring is back in place,just have to wire in the fans and the IATwhen it comes.even put the battery in and turned it over with the plugs out just to see if i had power there that was great havnt seen it like that for over 7 months now. tomorrows plan is to get the bracket for the tensioner made and fitted,get new plugs and refit the whole of the intake system.

Pudsey Posted April 21, 2010 Share Posted April 21, 2010 The magic moment is getting ever closer....... Great to hear that it turned over all okay, you have done a good job on the intake pipe in the end. Bet you can't wait... Quote Link to comment Share on other sites More sharing options...

Bet you can't wait... nope, its taken long enough to do im getting withdraw symptons.the intake pipe was a lot better this way cheers for your input there mate.sometimes you can look at something so long that a fresh look from somebody else is always good.trying to put money aside for the mapping so its definately close,been selling loads of stuff i have lying around cheap to get some cash in.

jagman Posted April 21, 2010 Share Posted April 21, 2010 When the throttle is closed and then opened again and air is recirculated ,it is common to have the ecu run very rich during this transient condition - usually it is vacuum sensed in the recirc valve line or pipework - to prevent the hotter than normal air causing det on rapid throttle opening does the Map 2 allow this? as it does not happen on a turbo car Quote Link to comment Share on other sites More sharing options...

jagman Posted April 22, 2010 Share Posted April 22, 2010 Just for those that are interested , after a chat with Barney today his setup would have boosted to a tad over 24 psi , which would have been erm -not good But now he is back on track and should boost to a more reasonable 12-14 psi , plus he will get a better belt wrap to prevent slippage He should make around 350 bhp maybe more given his exhaust manifold , but it the super quick onset of torque that will make the car /conversion some more info is needed regarding the valve springs - ie loading , and the exhaust valves ie material spec on the Na , so if anyone knows it would help perhaps some of the na-t people have some info .... and how did they work out under boost and what rev limit used ? the overlap seems well suited to a charger , so it is already there so to speak - should go well Quote Link to comment Share on other sites More sharing options...
Shane Posted April 23, 2010 Share Posted April 23, 2010 not sure ive just asked the tech guys on the map 2 forum.but i know a fiew people use them on the supercharger forum. sent you a pm adam need to pick your knowledge a bit deeper. When I had the Eaton M90 supercharger on my supra, I modified the re-circulating valve from a ford 3.8l engine which is vacum controlled. The vlave basically provided a free path between the inlet and outlet of the M90 when open. At tickover and low revs the valve remained wide open and as soon as vacum level became close to atmospheric pressure it closed and remained closed on boost. I still have it and will send a photo if it would help. Quote Link to comment Share on other sites More sharing options...

jagman Posted April 23, 2010 Share Posted April 23, 2010 As Barney already has a bov I suggested he link that to the inlet ,or use the recirc valve off a Cooper s -which also is vacuum contolled and easy to instal The only real issues he faces are the enrichment during throttle opening ,and the durability of the NA components When the throttle is closed (the charger is still being turned by the engine ) and the air is sent back to inlet -this causes pumping losses to happen ,which appear as heat -added to the air which is then sent back to the inlet -rinse and repeat - this cause a temp rise of the air going in circles - THEN you open the throttle again so the engine sees far hotter air for a few moments - this brief moment needs more fuel to cool the charge air -(usually done by the ECU on a charged car) But the ECU he has is for a turbo car and I dont know if it can do this without tricking it somehow The ECU could easilly see the IAT increase and pull the timing -that would cause a bog - Options would include a WI that is simply triggered by the throttle -but a primitive solution and somehow complex at the same time Adding another injector pre charger ,t pieced to the main fuel supply and triggered by throttle and a solenoid for a few moments (cold start injector would do ) Na component strength ?- pass , rods,piston cooling -pass , ex valves -pass ,clutch -pass ..... but I guess we will soon know Quote Link to comment Share on other sites More sharing options...

MAP enrichment responds when there is a rapid positive change in manifold pressure. TPS enrichment responds when there is a rapid postive change in the TPS this was the reply back from map.

jagman Posted April 23, 2010 Share Posted April 23, 2010 Thats good news ! - you can use TPS to alter the fuel -easy when mapping run the car on the rich side , due to the higher compression ,some power loss but safe ,it will also allow you some headroom to up the boost later 12 psi is the optimum boost ,but the beauty of the charger is you can run higher and it wont go bang like the turbos ,it just produces more heat , also you cannot spike in boost pressure -its always stable (slight increase as the engine revs higher and gets inefficient) I suspect you will be more than happy at 12 psi , but the next step would be to remove the head ,and get ported (gotta flow air:) and look at the valves esp the exhaust side ,probably bigger needed ,as well as the ratio to inlet , uprate springs , and a thicker gasket I know a man who wont be bettered for the head work and can get custom valves done if you wish it - I personally dont think it worth going on to this stage as the power delivery is so strong with a charger and traction becomes an issue but if money is burning a hole in your pocket ......

barneybrendan Posted April 23, 2010 Author Share Posted April 23, 2010 head work is definately something im wanting done,i can get hold of a spare head.i take it your guy would want the head to be able to give a price. engineers local making the charger pulley,tapping out the intake for the IATsensor that arrived today and threading the end of some pipe to fit the bov so i can recirculate it. will be keeping my eyes open for water injection aswell.been looking at some specs on the m90 once opend up for better flow ,seems promissing but need more evidence on the results to be convinced.12 psi will be great for a starting point for this year.

Hope the photo is enough to see how the vacum operated valve effectivley provided a bypass between the inlet and outlet of the M90.

barneybrendan Posted April 25, 2010 Author Share Posted April 25, 2010 cheers shane always good to see other options. got the throttle body fitted and the throttle cable is on starting to look more like its coming together.I have moved the bov down to the bottom of the rad area,will be easier for direction of the recirculation pipe work.Plus im fitting the map ecu IAT sensor into the pipe with the flange on it.This pipe is nice and thick and will just need drilling and taping out,and there shouldnt be a problem with heat soak. I dont like the look now with the blue connectors and alloy pipe,so im ythinking of wrapping them with the black exhaust bandage giving it extra protection from heat soak and more in keeping with the look im after. Off to the engineers 7am to give them the charger pulley,bov and the pipe with the flange on.fingers crossed they will have it all done in a couple days.
