terribleturner Posted February 19, 2006 Share Posted February 19, 2006 Well due to the amount of oil coming out of my bov im thinking i'll need to bring my single installition forward. unfortunatly i wont have my money available to me to go whole hog on it so am thinking of a plan B and was wondering of peoples thoughts before i commit. To save a part of money im going to run the turbo at around 500/550 so as i don't have to get the new autobox just yet. I'm also thinking that at this point i might aswell pick up a 2nd hand EManage and slap that on to run the lot instead of the expense on tuning the motec/autronic twice. Now the fuelling. Will i need a dual feed rail for this sort of hp?? Im thinking of using the stock lines, replaing the fuel filter, new rail with 720's and fpr. Does that sound about right??

Lucifer Posted February 19, 2006 Share Posted February 19, 2006 That sounds fine, a good step towards being properly single. I have here a demo car with that very setup on making 550, Emanage Blue, 720's etc. if you want a ride, come down one weekend. You can push the stock fuel setup (minus injectors) to around 600 with a pump upgrade, but after that the fuel does become.. stifled.

terribleturner Posted February 19, 2006 Author Share Posted February 19, 2006 Thanks for that Martin. My first plan with bigger hp was a complete fuel upgrade but for now this kinda made sense to me. Link to comment Share on other sites More sharing options...
Lucifer Posted February 19, 2006 Share Posted February 19, 2006 Thanks for that Martin. My first plan with bigger hp was a complete fuel upgrade but for now this kinda made sense to me. Yes alot of people think about doing fuel first, but BPU fuling is fine for 500 ish.... People forget that single turbos are able to boost less than 1,000,000 Bar!

Martin can you just clarify that for me, are you saying that the stock fuel setup on a j-spec will go to 600bhp using standard injectors and just upping the fuel pressure a bit?

Ian C Posted February 19, 2006 Share Posted February 19, 2006 Yah, the "minus injectors" bit is a giveaway, stop drooling at the thought of more power for no cash JB I suspect the stock fuel pump would need chopping out as well though, especially a j-spec... -Ian Link to comment Share on other sites More sharing options...

Branners Posted February 19, 2006 Share Posted February 19, 2006 You can push the stock fuel setup (minus injectors) to around 600 with a pump upgrade, but after that the fuel does become.. stifled. You see I read that as 'push the stock fuel setup (without uprated injectors) to around 600'. Soon as you add in uprated injectors you have to add in FPR, fuel pump and something to control all the extra fuel. Which is why I asked for clarification on it as this thread is in technical and could come up in a search about stock fuelling capabilities. So we are agreed that the stock fuel lines and rail will take 600bhp, but you need uprated fuel pump and injectors to do that on a j-spec.

Lucifer Posted February 19, 2006 Share Posted February 19, 2006 LOVL. I though I was up fro a right grilling then! LOL. Sorry if it was a bit unclear, my brain just bluts stuff out sometimes! As everyone knows the Stock J-Spec fuel system is good for 400 ish if everything was new. Aven on a 50k engine Ide change the Pump and Get the Injectors cleaned and tested. LOL again....

Will i need a dual feed rail for this sort of hp?? Im thinking of using the stock lines, replaing the fuel filter, new rail with 720's and fpr. Does that sound about right?? i ran 800bhp on the stock fuel delivery pipes. i put in 2 x walbros, Sard FPR, 1 stock feed splitting into 2 modified goodridge feeds feeding the Sard Racing fuel rail on each side (or hks) with 720cc Trust low imp injectors. my car is j spec man 6spd. just made sure i changed the fuel filter while i was at it.. i did the above before the single conversion, had the Toms Racing ECU with the SAFC2. car ran LOVELY. (now running on AEM EMS) but recently i have fitted a COMPLETE Fuel feed and return lines with goodridge lines everywhere including inside the tank (for the twin walbros). getting the car prepared for 800+hp. recently we did a project on a customers car (HKS T51R Kai BB Complete kit) with Sard Racing Fuel Rail, Sard 1000cc low imp injectors, its a UK spec with stock Auto box, its got AEM EMS, and we mapped it at only 1 bar of boost and its pushing out 500bhp to the wheels, NO issues!!! next month its time for a 3800 Torque convertor. in my honest opinion the supra stock fuel system (minus injectors) with the upgrade of pumps is more than capable of 600bhp. hope that insite helps and enspires you.

letmeshowyou Posted February 19, 2006 Share Posted February 19, 2006 sorry for the hijack, FM - how long will the standard box take that kind of power for?! Link to comment Share on other sites More sharing options...
JohnK Posted February 19, 2006 Share Posted February 19, 2006 Not all auto boxes will take that kind of power for long. Especially if you do a lot of WOT changes (full auto) Link to comment Share on other sites More sharing options...
Guest Bijal Posted February 19, 2006 Share Posted February 19, 2006 dont worry, i dont think its a "hijack" as its usefull for "terribleturner" i am sure, as he also has an auto box. that particular car mentioned - its been like this since 5 months or so. and he drives it everyday!!!! however, i have other similar project cars running same type of power with the stock auto box and torque convertors, some even 650bhp to the flywheel and no issues. some of these cars have been like this for 2 years almost. having said that i wouldnt recomend more than that to be honest. we always advise the customer that the risk is there, but luckily money hasent been an issue for these particular customers so they have been happy to accept the risks. i have 2 customers who have purchased 2 built auto boxes just in case there stock auto box breaks, but that was over 1 year ago and they are still going strong Link to comment Share on other sites More sharing options...
JohnK Posted February 19, 2006 Share Posted February 19, 2006 Well I can tell you mine drives perfectly day to day but at WOT it slips a fair bit on changes. Link to comment Share on other sites More sharing options...
Lucifer Posted February 19, 2006 Share Posted February 19, 2006 Depends which box you are talking about. Auto - Depends how you drive it, the 1-2nd gear Sprag is the weakens link, so giving it beans between the gears isnt a great idea for long levity. 5 speed - Don't even bother unless you like replacing syncros for a past time. Getrag 6 Speed - This is where you want to be for over 500 bhp, unless you want to drag then the TQ400 box... at a price with the 6 speed option.

terribleturner Posted February 19, 2006 Author Share Posted February 19, 2006 Well im gonna have the auto box with a 3800 tc installed for this set up. I'm just holding out for my redundancy then i can get the new box. At the end of the day if it goes straight away or soon then i can't imagine a 2nd hand auto being expensive. Thanks for everyones input. Link to comment Share on other sites More sharing options...

terribleturner Posted February 20, 2006 Author Share Posted February 20, 2006 Whereabouts are you Martin?? Bristol or did i just make that up?? Can i just double check about the fuel rail, it doesn't have to be dual feed does it?? And i forgot to say i have an auto cooler going on soon to so that should help the box out too.

Lucifer Posted February 20, 2006 Share Posted February 20, 2006 Yes im in Bristol. just off M5. NO you dont need dual feeds at all if you pump(s) are up to the job and you are not over driving them with silly Feul pressure. Link to comment Share on other sites More sharing options...
terribleturner Posted February 20, 2006 Author Share Posted February 20, 2006 Need to double check the pump but sure it's a walbro i got fitted a year back. Link to comment Share on other sites More sharing options...
