Mk4Gaz Posted October 4, 2014 Author Share Posted October 4, 2014 Almost there! Managed to start making my screamer pipe last night, and finished welding it up this afternoon. Also got the Intercooler pipework done, and engine boxes trimmed around the turbo, and re wrapped in carbon vinyl. The bay is now complete, so just got the downpipe to bolt to the 2nd decat, and make a support bracket to hold the weight of the system, and take any stress off the turbo. Then plug the ecu in, and turn the key Getting nervous now, but really pleased with how it's turned out aesthetically Quote Link to comment Share on other sites More sharing options...
supra_ufo Posted October 4, 2014 Share Posted October 4, 2014 brilliant work gaz, wish i could do half the things you could do! love how the engine bay is looking mate Quote Link to comment Share on other sites More sharing options...
Benjy Posted October 4, 2014 Share Posted October 4, 2014 And in the time took to post this on here and Facebook, you could have done the ECU at the least... GET ON WITH IT MAN!! Quote Link to comment Share on other sites More sharing options...

Abz Posted October 5, 2014 Share Posted October 5, 2014 Man you are a genius! I am loving the quality of the work, clearly you are thinking ahead & being able to do everything yourself! Quote Link to comment Share on other sites More sharing options...
Mk4Gaz Posted October 5, 2014 Author Share Posted October 5, 2014 Thanks abz, really appreciate the kind words bud Shame I can't get it running properly though! Seem to have an electrical gremlin somewhere in the ignition system Quote Link to comment Share on other sites More sharing options...
Mk4Gaz Posted October 10, 2014 Author Share Posted October 10, 2014 Went for mapping yesterday, and came back a happy boy! At 0.95 bar we made 435bhp and 430ftlbs at the hubs, and at 1.1bar it was 455bhp and 455ftlbs I don't know what the auto transmission losses are normally calculated at, but ive read about 20%? Which would equate to circa 540fwhp at 0.95bar, and 570fwhp at 1.1bar - although that sounds a little high for me? I can only run 0.9 at the moment, as the wastegate to manifold gasket started leaking after the 1.1bar run, so I need to fix that at some point. All the niggles were ironed out with the mapping, the misfire and everything else was all due to fine tuning which I was relieved about!

Mk4Gaz Posted October 10, 2014 Author Share Posted October 10, 2014 Cheers Alex, and a huge thanks goes to you for your generosity with the grade 8 plugs I only boosted twice last night, was heading to an mr2 meet with my old crowd straight afterwards, and it was soaking wet everywhere, but it certainly felt lively!

Mk4Gaz Posted October 10, 2014 Author Share Posted October 10, 2014 I don't I'm afraid bud, they did say I could've gone in the dyno cell, but I was too much of a pussy and hid in the waiting room with my arse cheeks clenched! Quote Link to comment Share on other sites More sharing options...

Scott Posted October 10, 2014 Share Posted October 10, 2014 Went for mapping yesterday, and came back a happy boy! At 0.95 bar we made 435bhp and 430ftlbs at the hubs, and at 1.1bar it was 455bhp and 455ftlbs I don't know what the auto transmission losses are normally calculated at, but ive read about 20%? Which would equate to circa 540fwhp at 0.95bar, and 570fwhp at 1.1bar - although that sounds a little high for me?

All the niggles were ironed out with the mapping, the misfire and everything else was all due to fine tuning which I was relieved about! That sounds brilliant! Only tiny things to sort out. What's your end goal boost wise? Don't get caught up in the hub/fwhp figures though. They generally work out the same/similar. The only time to add 20% is when you're measuring the power on a rolling road. Not really sure why it works that way but back to back runs on hub dyno vs rolling road (SRR) seems to show that the hub vs the fwhp figure are the same.

Mk4Gaz Posted October 11, 2014 Author Share Posted October 11, 2014 Thanks chaps, to be honest I don't have a particular goal to achieve, I got caught up in chasing numbers a few years ago with the mr2, and it often ends in tears with dented pride, and a very dented wallet! I just wanted to simplify the setup, and end up with a nice driveable, fast street car I always remember my mr2 dyno plots having the whp and calculated fwhp printed together. Mine made 260whp and 312fwp. The mr2s are said to suffer with circa 18% transmission loss, so that was about right - ish. I've always gone with whp, as we all know that fwhp is basically just a guess, a calculation done by the dyno that can be adjusted by the dyno operator. But, it would be nice to compare other people's results, especially as srr is used by a lot of owners, through Ryan mapping there. My tuner said that he'd mapped for 1.1bar, but was struggling to get a consistent power run on the hub dyno, as the auto kept kicking down into 3rd, so he's left the boost controller doing its thing to 0.9. He said once I've sorted the wastegate leak, to go back and he'll double check everything, and he thinks that at 1.1bar it'll be a hoot to drive, and about the limit without pushing things like the auto trans.

Yeah around 15-20% is the norm (15% for manual and 20% for auto, it's a good guess anyway), it's more to do with the way the hub dyno works though. Even though the hub dyno prints out "RHHP" it's actually more comparable to FWHP than it is RWHP, that's only from information gathered on this forum though. I don't know why this is exactly, it could be that hub dynos are more optimistic and give an inflated figure, or that dynos like SRR are heartbreakers and give low estimations, but it doesn't really matter tbh. The bum dyno is the only real thing that matters Quote Link to comment Share on other sites More sharing options...
