SHOW OFF YOUR TURBO PETROL/GAS PATROL

[turbmav]

Just got my turboed tb42 going reliable now and would like to compare/add to my rig the tricks other poeple have found to get more power and reliability out of it. Seems like a few people have done this mod or sorcing info on turboing the petrol patrols. Pictures and dyno sheets with specs on engine mods would be excellent. Here mine , bit jerry rigged but goes hard. TURBO HYPER GEAR TR44 INTERNAL GATE, BORG WARNER TOP MOUNT EXH MANIFOLD WITH 38MM EXT WASTE GATE, 3 INCH EXH ,600X350X75 FRONT MOUNT INTERCOOLER, 440 CFM GAS RESEARCH MIXER, MODIFIED TB42 HEAD, CRANE IGN RUNNING BP7ES PLUGS, 11 INCH CHEVY HAYS STREET STRIP PRESSURE PLATE WITH TURBO DIESLE CLUTCH PLATE, LSD 4.11 REAR DIFF.

lol sorry to dig at ya but that pod outta the bonnet just looks wrong!



thats mine i dont have any finished photos but ill upload some

[turbmav]

Haha yeh this thing been built on a buget and figured $40 dollar hole saw was cheaper than $400 snorkle. You should hear the bloody noise it makes when turbo in surge from the pod. It attracts too much attention but cold air is its purpose.

[Z()LTAN]

LOL THAT'S GHETTO SPEC!!!

and i love it!!!

Top stuff

[its aford not a nissan]

great effort , but , do yourself a favour and get rid of that pod through the bonnet or be expecting mr plod to be giving you a canary

[RIZZO]

yep i agree mate, top truck top job but get rid of the pod through bonnet, gota be room under there somewhere,

x2.... i would have said ridiculous...
change it mate... stick a gu blower on it to cover the whole. that'd look way better!

the idea is still sort of pointless,if you get water above the bonnet its going straight in, thats why snorkles go roof height and hopefully you dont get good storms where you live either. but if you like it thats all that matters.

[scott/gqfun]

thats just wrong. do u put a full face helmet on so no 1 can see u. i would'nt b seen in that

[turbmav]

This ain't going in water over the bonnet so why bother with a snorkle and water when rains actually makes it go better. The point of this post is to see other people's mods not to see if they like my filter or where I hang my fluffy dice or something.

[GUEEY]

Nice lamp shade! do you reckon you could make a couple for our bedroom bedside tables!!

[lewie]

note the red badge on the side of the car, deserves not much more than the lamp shade

Thats fair enough, but water and the internals of a turbo wont mix to well after awhile thats all. imo a $400 snorkel wouldve been better than what money will be needed to replace turbos let alone the DOT pulling you over for a properly unsecured pod filter. As i said if you enjoy it thats all that matters.

[tb45turbo]

i have just recently finished my turbo tb45 build. dyno results-353rwkw(473rwhp), and 735nm torque at 20 psi. will try and post some pics soon

[turbmav]

HOLEY SHIT!!! On nitros?

[80WEPN]

would like to see dyno sheet of that

i think the dot will be more worried about the obstruction in the drivers view , seeing as they book people with the big uhf ariels these days and spotties on top of the bull bar , even bonnet scoops have to comply with strickt guidelines , im sorry , it may work really well but the dot / plod etc will look at that and start rubbing there hands together

[turbmav]

Theirs no dout the cops/transport dept will spot that and go right over the car and I d be farrked. Thats why it sits in the shed most the time untill an outing comes up. but it just takes one cop to shut it down your right.

[PGS 4WD]

I'd like to see the dyno sheet, not shootout mode on a dyno dynamics though please.

We have made 385 rwkW on the 4.5, thats a lot of work, cam, pistons, rods, head work, extractor turbo manifold, 76mm Mister Turbo roller turbo, 4" exhaust 850 cc injectors twin efi fuel pumps .....and so on. We could make a lot more with better fuel, thats on pump 98. With water/meth injection.

Cheers

link is fixed for my pic more will be up shortly

[cooki_monsta]

there ya go, thats mine as it was before i stripped it thanks to the car being written off

[turbmav]

Looks good mate, any special mods(ignition,head work), are you using a ext gate? What size turbo did you go for?

[cooki_monsta]

ahh ignition, petronix ignitor 2 triggering a crane cams hi6S digital ignition, with a trc 2 ignition retard control, with map sensor (it retards spark as boost increaces), and that fed an msd blaster ss digital coil .

as far as motor work goes, it was bog stock, ran 8 to 10psi as the internal gate was a little slow to respond some times, and the turbo was a t3/t4 chinamans special

once it was written off i drove it round on 16psi and it flew, was like a rocket, but there was hints of valve bounce on the dyno when i tuned it way back in the day on 16psi, how ever it did produce a very healthy 160ish kw on 10psi

all up including complete gas system and dyno time, the turbo conversion cost me less then 4k, most of which was given to the gas joint but they did awsome work there tuning it, untill i blew the 425 apart, then i went down to a 225, picked up more torque, and its stronger

oh and i run a 3" full mandrel system (it just fits) and it has a single 15" hotdog it idles like a diesel but its loud as hell once the wastegate opens

[cooki_monsta]

oh i do have some tips for you aswell, change your lid to the alloy one, the plastic ones are known to flex on the b2 which can really fk up your mixes in positive pressure, also why are you using the low pressure gas port on the b2? is there any reason for it? just wondering

[bluemav]

just a question... but are you running solid gas line from body/chassis to the converters? looks like it and id be moving that 2nd converter away from the exhaust.. bad shit will happen quickly

[turbmav]

Your ignition TRC 2 boost retard is what i'v been looking for a while to my Crane setup. Just locked on 14deg for now. Yet to do any dyno time, hopfully soon to see where i'm at with A/R and detonation. I guess it would lean it out with lid flexing on converter's. Might see about exchanging them.

[turbmav]

Yeh the low pressure port on converter is just the gas prime feed for cold start. My exhaust sound very similar being 3"all the way with just a 12-15"straight through round muffler. Dos your exhaust pop and burble when off the throttle?

[turbmav]

I'm chasing more info on ignition timing ramp/total and lpg air/fuel ratio. I understand these figures may have come at lots of dyno time but maybe a hit at ballpark figures would be nice, like what total timing to get over 200rear wheel killowatts. Just tuned mine with 11.1 lpg a/r seems smoother maybe earlier spool time. Need more info please.

[PGS 4WD]

The total timing is not a figure you just stick in and it makes power. It relates directly to cylinder pressure, this is a result of boost pressure, intake air temp, static compression ratio, cam size and valve overlap. Most high boost turbo applications do not acheive the optium peak timing as detonation occurs before enough advance can be added, a higher octane fuel would allow more timing and hence greater power is made. At low boost, under 7 psi it is often possibe to acheive optimum timing, a good dyno operator with chassis ears/knock box can do this. 11:1 AFR is too rich for LPG, its too rich for most petrol applications and LPG stoich is numerically 0.8 higher 15.5 vs 14.7.
