Very, its how I started my post, but the more I think about it the more it seems like I have some thing to lose but nothing much to gain by doing so
No mate, that was the red front engined one with the same sticker set.
I am right in thinking is this the one that Was at totb last year that had a fire before hand when mapping?
Oh and when you doing passenger rides

Thanks, Its alright for a home made job, bit of a spec mismatch with the current turbo though, bit pointless using a 550bhp turbo to make 100bhp less, still thats easily sorted

No mate, definately not, the cams arent up for that power at high RPM and trying to get it at 6K would need monster boost and loads of torque, and the box just wont take that, and potentially the crank might not like it either (although ive got a DKE crank I can upgrade that to but Im hoping to save that for another engine really)

Boost addict
love turbo novas im seriously thinking of buying one of these in the summer, guy from by me has a 300bhp nova turbo which is immaculate just looks like a normal nova gsi thats been lowered 60mm.
great results there tho i bet thats a real handful lol

Thats enough to give 250@wheels, which is over 300bhp@wheels per tonne
So you get the same sort of acceleration at normal road speeds (ie 30-120 or so) as you would from a 500bhp escos
Properly cheap way to be very quick

Chip,
only just spotted this thread. Nice result. 4bhp more than me at 1 bar less boost. Obviously breathes well and the big turbo is working well. What was the torque figure. Quite low because of the low boost?
What was the issue with trying to get more boost in it but it not happening?

I think the answer is going up a wastegate size and/or down a tubo size, and it should be fine then, we literally just welded up a manifold that fitted the stuff I had laying around at the time which was a GT35R I got off Doug Stirlings escort and a 38mm wastegate that was left over from a group buy on them I did.
Ive never intended this to be the final spec of the engine, so its just part of the development process to prove which bits do and dont work.

Yeah its a bit of a giggle 
Certainly makes the 3 door feel very pedestrain on its T34 and 125bhp nitrous kit, as despite that probably being similar power, its about 25-30% worse power to weight ratio at the wheels due to higher transmission losses and more weight.

Oh, i was thinking that would be @ wheels, that .6 turbine properly drags the 35 down some then.... plus the cams not helping, i would of liked to see it ran again with a few changes to the above just out of curiosity, i think its your duty to do these tests and report back the the LET community,lol. Atleast baby jesus aint crying.

Will have to ask the cam companies if any of them fancy donating a set of solid lifter profiles in the interests of development, but I suspect they will have little interest in an engine they now see as old hat.
I'll have a bit of a think and decide what route to go down in the new year, want to take some time out from the nova for a while now and get on with some other stuff.

Yeah its the .63 housing, Doug specified that one to make it spool sooner, but its a bit of a mismatch really, better to get spool by going down a turbo size if you only want low 500s or below anyway, which is what he did, all part of the learning process

Lights look terrible, but trust me when you are hammering down the B roads of somerset late at night the last thing you think when you are driving is "I wish I had about 70% less light on the roads"
Golf lights look weird but work very well, nova lights look ok but work shit, also the nova lights would look gash with the big bumper, but without the big bumper I have nowhere to mount the 4 radiators on the front of the car.
Its entirely about how it goes, not how it looks with me basically, so Im not really bothered the lights look a bit out of place, but your coment is perfectly fair and accurate.

Its night and day different now mate, as much difference between it now compared to then, as in yours compared to an average stage 3 saph!

I havent measured the duration, and standard figures wouldnt apply with solid lifter clearance, around 250 degrees I should imagine though at .1mm lift
Id be looking at more like 270in and 260ex really to make proper use of this turbo, and probably 11mm of lift instead of 10mm

457bhp @ 6800rpm
Wasnt able to get the boost control working well enough for a full boost run, that figure was at 1.55 bar, going to need to revisit how the boost control works as I would like to get another third or half a bar into that ideally.
Clean as whistle on full chat
Manifold was loving it too, lol
Big thanks to Matt@Mtech Automotive for his patience running it up again and again and again just to keep getting the same figure everytime while I tried and failed to get any more boost into it!

excellent result!
would be interested to see the graph, as when i went out in it, i just remember how Little lag there seemed to be(especially considering the size of the turbo).. would be interested to see if the graph tell the same story!
felt nice at 0.8 bar.. i bet it fookin flies now! 2bar will be crazy

lol @ nick
im just quoting the figure out of interest im not claiming it to be 100% accurate. its just the only figure I have
if it ever goes on a dyno out of the car i'll update
pee vee
it feels a lot laggier now due to two differences.
first difference is this maps not finished yet so its losing a litle power offboost and second is its got loads more power on boost now
so where as before it wasn't much diferent on or off boost now its night and day.
will take you out again some time. its nuts at 6-7k easily comparable to dougs escort or porkies old 3 door in terms of the shove in your back
dingla. I figured if I have a nova it may as well be a weird one. lol
danny. yeah the engine has more scope than the chassis or transmision really. needs to be put on an m32 box and put in a vx220. lol
