savage bulldogs Posted June 18, 2015 Share Posted June 18, 2015 Closest graph I've got for a comparison is my v1 sti when it had the original engine ,440's ,tdo5 16g ,full decat and fmic (which should make it spool a bit slower ) This was at 1.2 bar Afaik Tdo5 16g's and vf35's are both journal based cores (not roller bearing cores) and are the spec's are fairly similar . I've got a boost graph of mine from earlier this year and it now makes 1.58 bar under 4k rpm on the rollers (a bit earlier on the road) but it's had a few tweaks so spools a bit earlier than a standard set up . I know that the sti higher lift cams make a bit better power but I don't think they have that much effect on spool times and would have thought your's should have spooled at least 500 rpm quicker .

savage bulldogs Posted June 18, 2015 Share Posted June 18, 2015 It does shift if you drop it a gear and hit that sweet spot [emoji6] Should really get it on the rollers again as I haven't got a graph for the power @1.58 bar due to my old apexi intake strangling it and not letting it hold boost last on the last dyno session Sent from my SM-G900F using Tapatalk Quote Link to comment Share on other sites More sharing options...
Tidgy Posted June 18, 2015 Share Posted June 18, 2015 TD04 will always drop off at the top end due to its size. Did they give you a boost AFR graph? Quote Link to comment Share on other sites More sharing options...

I'm not fussed for massive power as I wanted a quick point to point car without the need to be in the higher rev range, as I need my licence for work, I'm more than happy with the results and I know up to 90 I can get there quite quickly, any more and I'd be getting myself into some serious trouble [emoji16] Sent from my SM-G850F using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

stants Posted June 18, 2015 Share Posted June 18, 2015 I just put mine up to show the differences in spool between the two ☺ . pre map the delivery wasn't anywhere near that. Sent from my SM-G850F using Tapatalk Quote Link to comment Share on other sites More sharing options...

Tidgy Posted June 18, 2015 Share Posted June 18, 2015 power/torque is great for pub talk, but boost/afr is the important one 2 Quote Link to comment Share on other sites More sharing options...
Nevell Posted June 18, 2015 Share Posted June 18, 2015 Hi mate I know exactly where your coming from , I suppose subaru didn't put the tdo4 on for no reason what a good little turbo it is :-) almost no lag on them at all and no need to rinse the !Removed! off your car to get the power , I loved myn but after o.9'bar and 5k that was it my td04'started passing abit of oil so instead of buying twice I got a vf43 designed for the 2.5'sti one of the biggest vf turbos the inlet housing basically sits on the gearbox now lol massive compared to the td04 , my list of mods where Ihi vf43 turbo good for 370+ bhp bit more than the vf35 Sward 3port boost solnoid so boost control is perfect Hrc 255 fuel pump Sti pink injectors Decat up pipe toyo sports Decat downpipe toyo sports cheap but good welds etc so no complaints K&n panel filter Mishimoto silicone intercooler y pipe much bigger than standard Btt racing turbo inlet silicone hose much bigger than standard , (not sucked in at all ) Prfb7'plugs cooler rating Good service oils fuel filter etc Then . Mapped by Duncan graham She was mapped to 1.5 bar which she hits at around 4k pulls like a fooking train to the red line and wants some more lol , but it's a completely different drive it took me ages to get used to it lol , out of boost she fills lethargic slow , but on boost she so much faster than when she was standard I love it now ,bit for a while I thought what have I done lol and wanted my td04 back ,like the the old motocross bikes with band , nothing nothing bang hanging on for dear life , Duncan said my wrx tmic was holding her back big time , but as I'm a wrx with 5 speed etc best not to push her to far , but he mapped the turbo to come in nice to be kind to my gear box .,I not had her on the dyno yet so not to sure what exact bhp I'm pushing but a brand new BMW m1 tried to have me the other day and got a shock to silly speeds to which I declined to proceed with , but obviously over 300 bhp lol if that helps lol 1 Quote Link to comment Share on other sites More sharing options...
BoozyDave Posted June 18, 2015 Share Posted June 18, 2015 these are the graphs from my last car http:// ">http:// and the graphs from my new blob with the exact same turbo, decat up and down pipes, and top mount ">http:// ">http:// 1 Quote Link to comment Share on other sites More sharing options...
BIGD Posted June 30, 2015 Share Posted June 30, 2015 Hi ChrisD, The turbo spooling is normally set up by the remap when asked otherwise it will be standard timimg. Out of interest what grade engine oil are you using? Quote Link to comment Share on other sites More sharing options...

savage bulldogs Posted June 30, 2015 Share Posted June 30, 2015 Did the mapper say anything about the lag or struggle to get preload pressure on the actuator ? As if you've not got a vac line or actuator issue maybe it could be the modded wrx cat less upipe bore being mismatched to the turbo and headers ,but I will admit i don't know much about catted upipes cos classics don't have em . You Could just get yourself a Harvey trick upipe and a 3 port boost solinoid mapped in anyways . as they're probably the 2 best upgrades to lessen lag and let the mapper control the boost better Quote Link to comment Share on other sites More sharing options...
Tidgy Posted July 1, 2015 Share Posted July 1, 2015 TBH i doubt the mapper would have a clue Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted July 1, 2015 Share Posted July 1, 2015 Why's that tidgy ? I don't know who area 52's mapper is and tbh I'd only use my current mapper (Clive attowe) or if I had to use someone new, by reputation I'd choose Andy forest or bob rawl but I've never had any personal experience with either of the last 2 Quote Link to comment Share on other sites More sharing options...
Tidgy Posted July 1, 2015 Share Posted July 1, 2015 knowing what i know about the names on the dyno sheet i sugest get it look at else where, unless im refering to a none related grpah that is Quote Link to comment Share on other sites More sharing options...
