popped up to see the nova after work managed to catch dave hard at work just before he called it a day!

nova is currently 315bhp @ 12-13psi equates to around 265-270@ wheels

hopefully dave will finish up tomorrow and hopefully get boost up to 25ish

 

christ thats going be one lively nova theres a 300bhp one round my way and boy is it an animal. what power are you aiming for ?

 

nice one Gary , glad to see at last its getting there

 

what spec is the engine mate ? be interesting to see what goodies are on there

 

well had a phone call today to say the nova was boosting to 25psi and was making in excess of 350bhp ATW

dave's rollers only read up to 350 ATW so the rest of the graph flat lines, but we think its around 400-420 @ flywheel (360-380 @ wheels) as we have reached the limit of the t34 0.63 hybrid turbo and they are known to flow a max 390-420bhp

in a car that weighs sub 800kg will be one fast little car

i am collecting tomorrow with one tired operator and tyres that are almost bald due to the wheels spinning, but im happy its stayed together and everything has worked well

gary

 

cheers jay

sounds good! what sort of revs was it when it hit 350?

 

Good results although I very much doubt its over 400 on that turbo, especially at that boost.

Either way plenty !

 

Wow,very impressive.Where to in south wales are you? iv never seen this one around.

 

the turbo makes around 400 on cosworths +/- 10-20 bhp so i see no reason why it wont make close to if not over 400 on the nova! the turbo is maxed out it holds 25psi from low down till high 5k revs then the boost tails off

regardless to what you set the boost control solenoid too

25psi low down is at 40% duty cycle
higher up we put 100% duty cycle in and it made no difference

so my thoughts are that the turbo has reached its limit and cannot supplied the amount of air required higher up to meet 25psi

but either it will be plenty fast in a sub 800kg car

 

in in newport mate

 

awesome spec and great results thats going be one quick road car, i remember seeing a nova for sale on pistonheads a few years back was around 400bhp and 4wd

 

Shame you chose that turbo really as it is ultimatly holding you back a lot. And I find them quite laggy on LET's!

Still be a lot of fun though

 

Agreed, 3071 or a 3076 would have been a better choice really

 

Is this Dave Walker who is doing the mapping ?

If so, dont forget to get 3 maps done and only pay Ł250 for the lot **

** Info supplied by Tabby

 

WTF

 

No its not

 

thats good news then

 

looking good, should be fast as fuck!

 

a good mate of mine has just got his Corsa turbo runnin nice after 2 rebuilds and trying to run it in on 26psi!

made 440summit bhp with a nice 100shot of nos when needed



looks aint to everyones taste... but it F***ING shifts!

 

Whats spec on the Corsa?

He had it down strip yet?

 

i dont find it laggy at all tbh but maybe tat is because the car is so light, overall i think its fantastic

 

I expect it pulls like a missile. But if you could experiment with other turbos in the future I bet you could get more drivability out of the car.

 

Cool,im not far away in merthyr tydfil.Got a nov too but not quite as extreme as yours will keep an eye out for it.Theres also a yellow one in newport i was told with a big power let,something to do with west coast customs?

 

there was another yellow turbo around 400bhp mark (my mate gareth owns welsh coast customs , powerflow dealer) but its now been broken for bits and sold back last year!

 

the nova is now safely home in the garage to say i am over the moon with the mapping is an understatement

it idles perfectly from cold, on 750cc injectors and 3 bar fuel pressure

havent driven it properly yet only off and on to the trailor and down the short run up the street and into the garage!

i have a graph but it only reads 278bhp @ the wheels at 4250rpm it flat lines to 6500 before dropping off

torque flat lines also at 330 ft @ the wheels at 4400rom

the rate its increasing the mapper worked out that its around 350-360 @ wheels

which equates to 400-410 at flywheel

its holding 26.8psi


oil change tomorrow i think, a final nut and bolt check fit bumper and get it mot'd early next week

big up to dave young at mech motorsport he has spent in excess of 20 hours on it, i am very happy finally

ebngine did 500 miles on the rollers over the last week with out a single issue

 

absolute awesome results there always loved novas (used to own a highly tuned sr ) but with this engine in and the right suspension/brake set up they are a real weapon i fount a pic of the green 4wd nova turbo the other day on my pc that was around 400bhp as well

 

brilliant news mate bet your over the moon

 

why did it flat line ,did you max his rollers out ? great power .

 

yes the rollers were maxed out, but the rate it was increasing at 3750-4000-4250 was 26bhp per 250 rpm

his rollers are fine usually for what he uses them for mostly n/a engine which never see 270-300 ATW on very few occasions he gets some powerful and it just flat lines!

 

cheers mate , yes i am very happy

 

cheers , yes i am very happy

 

by the looks of the graph and having to estimate as it flat lines at 4250 @ 278 and drops below 278 at 6500rpm

350 at wheels calculated on the graph using the current rate of acceleration is around 5200ish rpm

 

yes if i do upgrade it will be for a gt3071r or 76r but its nt on my list to do's for a while

 

well done fella,


saw the update on you msn lol ,

beef

 

cheers, shoul;d see some good 1/4 mile times and hopefully be fun on the track

 

Shame that.Same thing seems to be happening to novas as cossies,they get broke up for parts.
Fantastic results though from your car,hopefully il see it around one day and have a nose around it.Is there any nova meets around south wales?

 

it will be on track a but this year i wont drive it on the road much, may if i find it reliable take it to the ring in may or june!!

here is the graph


this is wheel horse power

 

thats impressive be good get it on a set of rollers which can handle the power
