i'll most prob be raising the boost & remap with the new engine rather than invest & fit another turbo. will be good to compare spool responses.let me do some boost gauge vids @ 1/2 throttle and wot before you make any decisions paul ? (i just need to refine this rrprv firsti,ve got 20psi and 40psi atm, but its still lean @ wot :doh

thats fuel pressure paul :grinning: not boost lol40psi!?
was gonna say, block woulda gone boom if boost was that high :laugh:thats fuel pressure paul :grinning: not boost lol
20 psi @ idle and 40psi when there,s no vacuum in the mani (using that austin mini vacuum advance mech)
looks like i,m gonna need 3 x fuel pressure @ wot compared to idlei can see why many proper rrfpr/fmu are 6:1 ratio !
michael from holland ran a 5th injector for 2 yrs iirc eh kris, but i,m trying to keep it mega simple tbh, this reg is fueling really nice @ idle to 1/3rd throttle, but wot is megga lean stillfrank : what about a 5th injector, activated on boost...like a constant spray instead of pulsed? Not sure how much it'd effect the overall rail pressure though.
Yeah i can remember a few people using 5th's. I know mine needs a good bit high up iirc something like 20% extra (emanages additional injection rate on the 1.6's), thats still a bit too rich really as the maf seems to be going off the chart at about 5.5k.michael from holland ran a 5th injector for 2 yrs iirc eh kris, but i,m trying to keep it mega simple tbh, this reg is fueling really nice @ idle to 1/3rd throttle, but wot is megga lean stillmight need to resort to fitting the VAFC

but dunno how high i could increase boost to safely when it involves long WOT periods (especially the long straights at nurburgring) and maybe sudden launches (santapod?) before one of the stock components breaks (HG, conrods, 1.3 gearbox, driveshafts, cooling?) or it begins to detonate if the compressions not low enough?Yeah you'll be losing a bit with the manifold leak, slow spool does seem to be the best excuse to up the boost and make more power on the new engine lol.

jim gr munched his g/box then fitted a par gearset, then munched a driveshaft iirc paul, and i bet he has 230+hp.but dunno how high i could increase boost to safely when it involves long WOT periods (especially the long straights at nurburgring) and maybe sudden launches (santapod?) before one of the stock components breaks (HG, conrods, 1.3 gearbox, driveshafts, cooling?) or it begins to detonate if the compressions not low enough?
anyone recall how much torque & HP the stock 1.3 parts i mentioned could take before obliteration? i think someone from greece had turbo'ed upto 200bhp till his driveshaft went?
Not sure anyone will know to be honest...head gaskets have gone at low boost, stanni? (sorry if not you mate haha) killed a piston, and yeah the driveshaft twisted itself free. First two were all lean fueling related iirc...anyone recall how much torque & HP the stock 1.3 parts i mentioned could take before obliteration? i think someone from greece had turbo'ed upto 200bhp till his driveshaft went?
lol, mate, correctedYou've got one to many 0's there peposhi. 100pence in a pound not 10.
Sounds like a plan lol.should prob keep within 200bhp then
AFR are fine, stronger pistons, and if the box or driveshafts break i have a spare and then lower the boost a tad![]()
wet road again i,m afraid paul, but http://www.youtube.com/watch?v=oBlRV355RgM&feature=youtu.belet me do some boost gauge vids @ 1/2 throttle and wot before you make any decisions paul ? (i just need to refine this rrprv firsti,ve got 20psi and 40psi atm, but its still lean @ wot :doh

pretty good response eh pauleey thats near instantaneous boost:grinning:
just thinking there's lota difference in "spool from rest" time between WOT at my 3k threshold point and WOT near the limiter.
when i ask for max boost at 3k it takes like 1.5s to respond.
from higher revs it takes bout 1/2s
yes 1st gear rolling start paul, here,s one in the dry and you can see it spool up from slightly before 2k (about 6 secs in)was that first rev with clutch down or 1st gear launch/wheelspin?
i,m not sure why i short shifted paul :blush: the leanout is only slight with the current (1/2 throttle) throttlestop fitted.nice. 20-60mph in 6secs is bout the same as on my last datalog vid but that was uphill. ur short shifting cos of WOT high rev lean out?
.
nice one:grinning:i,m not sure why i short shifted paul :blush: the leanout is only slight with the current (1/2 throttle) throttlestop fitted.
the 260/10mm inlet cam is the next job, and i,ll do another vid to compare eh![]()
Are you using a slim line fan?
intercooler covers over 1/4 the rad so a front fan would be tiny n noisy n not as effective. its a stock fan dremeled n bent to fit, does the jobor a front mount fan
now thats a thick rad:grinning: is it not full width? shame a full width alloy racing micra rad is soo expensiveNice, looks just like the one we used to have on the car before the upgrade to an alloy rad.
Mad how they compare to a stock one when you compare extremesStill, a full width rad would be awesome for a boosted motor

yeah exactly same plumbing as normal, just a thicker core. the two small aux oil cooler pipes at the bottom are independant and just form a short pipe inside which frank posted a pic of earlier.Wow so theres only 1 in and 1 out on the rad?
