something seems to be holding my blown verada back. New low restriction cat and exhaust being fitted this week exiting into stock looking black dump tail pipe.

ecu change next if exhaust doesn't do it. This would be supplied by sprintex but would void the warranty.

Of course there is always the supercharged 380 to consider. It is claimed to run 6 seconds flat to 100 in its standard tune. A bit of tweaking should easily see a high 12 quarter. But it would be a bloody horrible experience in a front wheel drive.

you wil find the s/c is holding you back ;)


i have a sprintexed awd with extractors 3" metal cat and custom 3" exhaust that splits into twin 2.5" mandrel bent all the way wank wank wank

anyway.....

if you do this, be prepared for no change or to go slower!! lol

my car drives beautifuly but dosent go that well, and it's due to the tune...

(did make 148kw atw 30deg day at 5psi running like puss)

sprintex assure me that with my exhaust modifications the supplied ecu blah blah blah...

so it's getting a haltech interceptor atm if the slacko's ever wire it up...

the s/c'd 380 dosent do 6's reading all the articles on it it dosent seem to do much at all, lol

cittris's s/c'd vrx which is a stock vrx auto fwd did 14.45 1/4 before the tune and now he has 14-18kw atw more and car is a lot stronger, so i'd say he's easily doing 0-100 in low low 6's and low low 14's

the difference is between the awd's and fwd's apart from less hp on the road due to 2wd vs awd.. and slight weight disadvantage is the seat of the pants feel... the 2wd s/c magnas feel much faster as you look at the throttle and there wheel spinning and off you go, where as in the awd there is none of that just a smooth power delivery that makes the car feel and seem slower than it actualy is..

Nah dude if he has a stock exhaust system on there now, I'd pretty much guarantee he's going to notice a difference. The system (the muffler, really) is very restrictive, even without a supercharger.

Freak knows what sort of times he'll be running. Too hard to guesstimate.

There's nothing to lose by upgrading the exhaust on a Magna... except money.

Don't go too big with the exhaust. 3" is pushing it and if you go 3" just get it straight through, you'll lose power going to a split system. Make sure the muffler is a high flowing one. If you want the most out of a Sprintex kit you need to get it tuned properly and lose their rubbish ECU. That seems to be the crux of the problems for all Sprintex kitted cars.

Also re the S/C 380, I've read reports on another forum that in-house testing they're pulling off 0-100 times of 5.8.

the sprintex kit dosent come with an ecu..

smoke and mirrors thats all :bowrofl:

and dont go 3" cos you wont ber able to quieten it down to an acceptable level...

i went duel cos it aa solution to the noise, 2 pipes with muffler on each, cos with awd there isnt anywhere to put 2 mufflers

ive got my new exhaust going on my s/c ralliart next week. going from the ralliart headers which are press bent magic to the rpw race spec setup. their off getting ceramic coated in the next few days then the install. I reckon i'll get a bit more puff out of the change with a dyno run in a few weeks at autosalon. last run was 195kw so with the new extractors and a fuel pump that works, fingers crossed for 205-210kw atw's

btw, still running 2½ inch pipe from the cat back as i was told it will flow to over 500hp

3" is nice, 2.5" ample, dual 2" perfect as you get the flow numbers of a 3" without the noise and with better low and mid rpm velocity (read: "scavenging").
Can get a twin inlet/outlet barrel resonator and twin mufflers into an AWD - mines getting it within the fortnight. Redback resonator and a pair of 2" staino Zetti muffs for some bling at the rear end. :dancin: Remember to oversize your cat; i.e. if you're running 2.5" single pipe use a 3" high flow cat. Peace.

in addition to the above dont be tight and spend a few extra $$ for a full metal cat...

the s/c creates enourmous temprature at the end of the headders, much much more so than a n/a magna, and a cheap ceramic cat will melt like i was shown

the non warrantied piggyback ecu that sprintex are offering seems like the way to go for that magical 250kw flywheel goal.

My blower is working fine, making rouglhy 7psi all the way to 6000 rpm, then peaking at nearly 9 psi before the cut out.

the tune must therfore be rubbish and judging by the colour of my tailpipe I would say it is too rich at the wrong time.

you will find as did i that it's set to run very rich so it's reliable and safe, you will also find that with a better breathing engine intake mods extractors and exhaust, you will still gain power, and the boost will come down 1 psi or so (good thing) i made 148kw atw on 5psi (dyno boost gauge on 30deg day 4th run after heatsoak set in)(my car is 6.5psi on a cold night, and we all have the same blower pulley)

if 250kw is your goal, you will want to look at the inlet temps and how to lower them... i have water injection being fitted tomorrow, this will go some way to reducing the enourmous temps in the intake post s/c

So this thing could kill any HSV with a little bit more development......

Maybe something pre-VE... but aren't E series HSV's doing the 0-100 in around 4.95 seconds?

I wouldn't get too excited. There are still issues of driveability and traction to consider.

Claimed is 4.96, but I think in testing the magazines weren't able to get near that. I could be wrong. I think they're slower over the quarter than the SS tho (high 13's?)

Yeah I wouldnt depend on anything the manufacturer tells us about times... but then again, I wouldn't take what most magazines run in these cars too seriously, either.

Either way... I wouldn't buy either the HSV or the 380, haha.

Haha, me neither. I'd buy an EVO. :cool:

Anywho, keep us posted about your exhaust mate.

Now have the custom 2.5 inch system with high flow cat and new performance muffler.

Has standard looking black dump tip exiting below the rear bar.

AAC took care of it and the tuning to suit. Total cost 1G.

Much louder, not too ricey, but has unleashed a bit of power. The exhaust noise now balances out the supercharger whine a bit, not that it was a bad thing, but was turning too many heads if I revved it a bit.

First ever speeding ticket in this car - nearly 10 kmhr over the limit!

The cops normally don't even notice, probably feel sorry for Verada drivers.
