I can believe 0-100 in 13.7 seconds from a well tuned Astra SRi turbo is possible... but then if it was tuned it would do 0-60 in well under 6.6 seconds (which coincidentally is the time for a standard spec Astra GSi turbo).
No, i'v done it on a dual carriage-way, and when I saw the bloke later he asked what I had under the bonnet because he was struggling to keep up.
More power and lighter = faster.
The Astra GSi turbo does 0-100 in 17.3 seconds... and the SRi turbo can only be a few tenths of a second slower at the most.
Astra sri turbo does 0-100mph in about 20-21 sec mark. It's a FAIR bit SLOWER than the gsi to 60mph and 100mph.
Don't compare the sri turbo with the gsi as they are not even in the same league!
They are identical apart from the interior and 10bhp. SRi turbo's are limited editions, which makes them rarer, which is better.
The SRi Turbo was a limited run model to satisfy the needs until the GSi came out, they're both identical apart from interior and a different map making an extra 8bhp. You will find there is nothing between the two.
As to the coment about 0-100 being in the 20's is completely untrue. As I own one of these after previously owning an MG ZS 180, which does it in 17.5, the Astra is a lot quicker, in the 15's I'd say.
The sri turbo covers the 0-100mph dash in 22.6sec and the 0-60mph dash in 7.7sec. It just isn't in the same league as the gsi. The gearing is set for long distance cruising, rather than acceleration like the gsi.
My 15.2 1/4 mile - I did hit 91mph over the distance in third. It wouldn't be that much time to get the thing to 100. 17-18 seconds in my estimation.
22 sec 0-100, 7.7 0-60. I own both a 02 SRi T and 04 GSi T, and they are identical in speed and handling. Don't know what the person above is on about. The gearbox is identical. Vauxhall claimed lower times to get into a lower insurance group.
I think some people are confusing the limited edition 189bhp Mk4 Astra SRi turbo with the heavier and less powerful 170bhp version of the latest Mk5 Astra SRi turbo.
I wrote the comment on 16th march, and meant to put a? after the times. as both will do 0-60 in under 7s and 0-100 in 17.2s, tops out at 147mph.
Mk 5 is 100kg heavier and 20bhp less. nothing compared to the mk4 limited edition turbo.
As said earlier, the Mark 4 Astra SRi turbo & GSi turbo have EXACTLY the same engine. The ONLY difference performance wise is the ECU mapping... which gives the GSi a massive 8bhp more than the SRi turbo.
I was being sarcastic when I said there's "a massive 8bhp" in it. SO many people seem to think there's a world of difference between the GSi and SRi turbo, which is frustrating.
What a bunch of anoraks.
My CDX would beat you all!
OK, little boy.
Picking up a mint Astra SRI Turbo tomorrow, did consider a GSI but felt the SRI was better value.
GSI leather is pretty poor and looks like its been to the moon & back even though it might have only done 20k.
The interior on the SRI might be a bit dreary, but at least it won't wear in 12months.
Wish me luck with the speed cameras...
Power to weight ratio speaks for itself and the Astra doent have much. If you can be bothered to look it up you will find that its very similar to the St 170 in this area. No way will the Sri turbo cover 60mph in less than 7sec or 0-100mph in less than 20sec. It also suffers from poor handling and lifeless steering.
The Bugatti Veyron has 566bhp per tonne and the TVR Speed 12 has 999bhp per tonne, yet the Bugatti annihilates the TVR, therefore showing that power to weight doesn't mean anything.
But if you look at torque per tonne, you find that the Astra has more than all the other hot hatches in torque fiqures.
I raced a modded gold audi a3 turbo down dual carriage way and showed totally demolished him I had a full car as well when he only had 2. his face was a picture.
I got my SRi turbo phase 1'd and the 1st cat removed. Now pushing 254bhp with a Powerflow cat back 287ft/lb. Scarily quick. Caned my pal in his 350z gt4.
Very nice car and pretty quick to who cares about gsi I've only seen old men driving them.
Gsi leather gets tatty too quickly, gsi has better headlights and body coloured rubstrips.
My Corsa would fry any Astra Audi or anything.
Your Corsa must be modified then. What's to say a highly modified Astra or Audi wouldn't fry your Corsa?
Only way it would do that is if it had z20/c20-let. i'v been in a nova with c20 let running 350bhp and the things unsafe.
In a Nova, fair enough. I know of a chap with a 280bhp LET'd Mk2 Astra GTE though and it's perfectly safe,... in the dry ;-)
Yeah.. in the dry, but hit a wet patch and watch that back end step out. Either that or understeer.
I have an SRi Turbo. Can I get my traction control on a switch, and how much does it cost?
Yes mate, can add it simple DIY. I have all the Vauxhall part numbers if needed! email firstname.lastname@example.org
Astra sri weighs 1210kg and gsi weighs 1245kg.
Recently fitted a GT28R turbo, Dbilas manifold, forged pistons/conrods, lightweight flywheel, Sachs clutch, Quaife diff, 6 speed gearbox, water injection, racing fuel pump, and revised software.
Running 428bhp and 480ft.lb.
This car's acceleration is immense. I've never been in anything so quick. The interior's been stripped of unnecessary bits, and it will reach 60 in under 4 seconds, and do 0-100 in under 11. I've had it off the clock (160) at 4250 RPM. It red lines at 7k.
