VulvaS40T4 Posted November 17, 2014 Author Report Share Posted November 17, 2014 (edited) New Fuel pressure sensor and Crankcase pressure sensors are on. Tested 3.gear pull from 5000-8250rpm with winter tires it takes only 1.0s to spin tires to rev limiter. Fuel pressure follows nicely boost 2.5bar and 4.5bar fuel pressure (2.0bar base fuel pressure). http://i119.photobucket.com/albums/o143/VulvaS40T4/fuelpressurelog_zpse399a18a.jpg~original http://i119.photobucket.com/albums/o143/VulvaS40T4/crankcasepressurelog_zpsadc6f987.jpg~original Crankcase pressure is getting too much pulses from crankcase and its not readable. On my civinco standalone you dont have any software filters for extra sensors so im planning of making electronic map sensor filter for that. Like this. http://www.miataturbo.net/ecus-tunin...circuit-48665/http://www.miataturbo.net/attachment...lter-schem.gif Edited November 17, 2014 by VulvaS40T4 Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted November 17, 2014 Report Share Posted November 17, 2014 Those sensors look the same as the 0-100psi range I have used for fuel and oil pressure - I have only had problems with the terminals coming out the housing over time. For CC pressure/vac I used a Volvo NA MAP, since the table is readily available. Quote Link to comment Share on other sites More sharing options...

VulvaS40T4 Posted December 8, 2014 Author Report Share Posted December 8, 2014 (edited) New aluminium radiator on place! 50mm vs. stock 25mm radiator. There will be two of those cooling fans which will cover nicely hole radiator. Old 1998 years original radiator was little worn but it did its job nicely! http://shop.j-spec.se/sv/artiklar/torque-racing-40mm-aluminiumkylare-volvo-s40-_-v40.html Edited December 8, 2014 by VulvaS40T4 Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted December 9, 2014 Report Share Posted December 9, 2014 Nice! About time you moved on from that old rad. Only so much luck you can have Quote Link to comment Share on other sites More sharing options...
VulvaS40T4 Posted February 8, 2015 Author Report Share Posted February 8, 2015 Updated on first post my cars latest specs. There is winter here so only daily driving with massive wheelspins. Summer starts here on May so then more testing with summer tyres. 1 Quote Link to comment Share on other sites More sharing options...
Propain Posted February 8, 2015 Report Share Posted February 8, 2015 (edited) Thanks for updating - this is my first post here in this forum, as I subscribed just for being able to answer and follow to this thread. I am very amazed what you and your friends did with this little four bangers - especially as they all seem to be daily drivers (I bet with -30 deg C in winther?)! After doing fi BMW's for years, our laws have become harder and harder and I had to watch out for a factory turboed car. It seems that I have found the proper car to start with - so let my thank you for all the infos you share here - this gives me very good input, as I am totally new to Volvo! BTW - Is there also a thread where one can find the specs of Vekku's V40? Or are they similar to yours except the bigger turbo?

VulvaS40T4 Posted February 8, 2015 Author Report Share Posted February 8, 2015 (edited) Thanks. Yes -30c is normal here in winter and with block heater not a problem even i drive with E85 ethanol all year, no gasoline in this engine ever. Nice that you have chosen Volvo. These engines T4,T5,T6 are very good when looking big power. No there is no public thread about my friends Vekku's V40 T4. Also some of the specs are not in public share, sorry. Main differences to my car are: Holset Pro55 71/80/22# turbo on season 2014-> bigger on this 2015 season, still secret. Bigger cams, specs secret. N/A B4204S2 head with stock 32 / 27mm valves 149mm h-profil rods + lower JE pistons with 9:1 compression ratio Megasquirt 3 ecu S60 T5 stock coils (direct ignition) 2 x 044 bosch fuel pumps -> 2015 3 x 044 bosch fuel pumps 812hp 2.8bar E85 on 2014 and 900-1000hp 3.5bar goal on season 2015. My car is daily driven and Vekku's car is summer driven "race car" for standing mile events... Edited February 8, 2015 by VulvaS40T4 Quote Link to comment Share on other sites More sharing options...
Propain Posted February 8, 2015 Report Share Posted February 8, 2015 Thank's for the infos!!!! I'm also impressed that you reach those numbers with standart size valves, mild porting, etc. - I had to spend tons of money in head porting, bigger valves, arp stuff to keep the head down, stroke the engine to 3 litres and pay for 6 pistons/rods instead of 4 - and even then I made not more than 750 bhp on E85. And today it isn't possible to drive a turbo converted car on our streets - too much young police officers who know what they see, when they look in a n/a cars engine compartement and theres a big snail! E85 in winter? Sounds good to me! Normaly we stop using it at +5 deg C and below. I never saw a block heater over here - I bet that is standart in Finland? Have the B4204S2 n/a heads better better flow numbers? Or better valve train for high rpms? Could I also go with the 98-99 B4194T for 700+ hp, or is the T2 that much better? I know they have different valve trains, but maybe there are other advantages? Sorry for all my questions - as I told you in my post above - I'm a real Volvo newbie - hope to become an oldie somewhen Greez from Switzerland (where we have warm -16 deg C up in the mountains) Quote Link to comment Share on other sites More sharing options...
VulvaS40T4 Posted February 8, 2015 Author Report Share Posted February 8, 2015 These injectors i use Bosch EV14 2200cc 3bar (2bar now on my car 1720cc) cannot handle normal gasoline very well and also injection time is even now close to 1.0ms which means injectors are only under 1% open on idle 1250rpm with 14:1 afr. Also when using only e85 engine is very clean inside and no carbon build up on engine. Block heater is installed rear of engine under exhaust manifold and its warms engine from outside. 2hours use -20c weather and your oil temp is +5c. B4204S2 has better intake ports but needs custom intake manifold and stock T4 intake manifold wont fit with that. Also you need to swap exhaust valves from T2 engine which have natrium filling. It has also 6mm valves like B4194T2 engine has. Nothing else is different little bit better flow. B4194T engine can be used but you have to make crankcase breathing holes under crankshaft between cylinders. These are stock on T2 engine. Also you have to convert cylinder head to use solid lifters like T2 engine on stock. Valves are 7mm but thats no problem. T2 engine is that way better so you have solid lifters on stock and T engine has hydraulic lifters which limits max rpms to 7500rpm. Quote Link to comment Share on other sites More sharing options...
