Any one give me a rough guide of what 0-60, top speed and BHP to expect out of the following 7.
Pinto 2.0 (rebuild with almost all new internals)
Piper 285 cam, Twin Dellerto 40's, Electronic Ignition (Fast Road Setting on the Electronic Amp) Diff is out of a J Plate 1.8 Sierra. Type 9 5
Speed Box.
I am sure i should of asked this question before i started building. :-)
Cheers
Ash

about 5 and a half to 6 and a half seconds to 60 as for top speed I presume it will start to slow down at 120mph but trickle on for perhaps another 15mph so 135
No that's probably fair to say at that level of tune.
No idea what my top end is but I can hit 60 in less than 4.5secs
hows that been timed andy
I wont go above 90mph in mine as its just not comforable at that speed.
my 0-60 is about 5-6 seconds with a 1.8 turbo, the problem i have is traction.

I would guess my pinto cat is around the 6 mark.
Thats on weber 45s and fr32 cam.
Under 4 secs with my VX XE engine (just over 200hp), need to time it properly with datron but deffo sub 4 secs.
traction not a problem on yoko a048r's on 14" wheels and soft rear springs.

Racing a VX 2wotsit turbo that does 0-60 in 4.7 and I beat him
lol
Really must get on and time mine. I think I am heading to a rwyb in the near future, but one of the issues is transmission parts failing!
I thought the lack of traction associated with 7 type cars would save the transmission, but I don't seem to suffer from the expected levels of
wheelspin!
So far its 1 x 100mm "lobro type" CV joint failure (brand new one) but I fear the gearbox could be the next bit to start crying

135 MPH i somthing i built 
feck me. What have you done to this pinto to make it such a monster! I want the same done to mine! lol

Although they haven't gotten to the point of failing (replaced first) I've killed a diff and a type9 in a year.

very nice! Where did you get that done?
Do you mind me asking how much it all cost. cannot think for one minute it was cheap!
Probably cost about £1500-2000 for the parts.
A friend did the head work and I did the final assembly.
P.S. I don't keep track of the cost cause it would scare me!
[Edited on 18/6/07 by andyharding]
great! Sounds like you have a monster
Is that a standard type 9 box?
I am amazed you can get sub 5 seconds with a pinto?
Yes although I'm thinking of getting a beefed up one soon.
How do you manage the gears - I found that 1st is so short you need to use third to get to 60.
I could get to 60 in second if I reved the nuts off it, but then 1st and 2nd gears are so different the syncro mesh won't let you into 2 until
the rev's drop and then you lose more time.
Mine was a standard Pinto and was around 6.5-7.0 sec's, really impressed if a Pinto can be tuned to lose 2 sec's from this.
Mark.
I'm just in the middle a some diff work.
When I had the VX I had a 3.92 in. Redline is 7000RPM and 1st gear was useless. Could miss out 1st and nearly get 60 in 2nd.
With the 3.62 in I will nearly get 70 in 2nd and probably still won't need 1st.

Best ask Vauxhall - it's their published figure.
True enough. When the new diff is in I'll try and do a timed run.
I have a 3.62 diff and as far as I know a std type 9 box, and according to the speedo (which according to the SVA rollers was zero error at 90 mph) I
can easily top 70 in second gear, though I do have 7500 revs available (but then I imagine you won't be far short of that with the pinto)
1st is easily useable as well
The only person I know that has done an actual timed 0-60mph run on here is Al (Wadders).
IIRC he achieved 0-60mph in 4.98 secs with a ZX9R engine fitted and went on to do the quarter mile in 13.524 seconds with a terminal of 100.68mph
Al's 13.524 secs compares with a quarter mile run we did at 12.523, therefore surely we must have done 0-60 in at least 3.98 seconds

Sorry guy's but what a load of bull5hit, before convincing someone about the performance of your car, get some proper data to prove it,
the fact your mate timed you on his mobile, or you've done it on your digidash, or you beat a car that can do it in 1 nano second, is a load of ****
when you've got some real proof you car is that fast, then post it up.
hearsay's one thing but facts are another.
so in reply to the original question, i'm not too sure but from what i've seen similar spec'd cars can do the 1/4 in around 14.5-15 secs and terminal at around 90mph.
so at a guess, i'd say realistically your looking at around 6-8 seconds to 60mph
also while where on the subject, i've yet to see a standard bec get there in 4 secs and they only terminal 1/4 at around 95-110mph and thats in 12-14 seconds.
only official figures i've got to compare is 0-91.78mph in 7.736 seconds, thats was with the last indy i had
Chris
Im not sure what Chris got with his S2000 Indy but the best Ive seen from a normally aspirated BEC is a 175bhp ZX12 Locost doing mid 12's at 115mph, so I would have thought to get into the mid 11s is going to need more than 200bhp with the weight / gearbox disadvantage of a car engine, and/or maybe sticky slicks. Could be wrong though.

Hi Nat, it wasn't aimed at you the previous post, it was just a general post regarding the wild claims people make on forums.
i would say low 12's would be acheivable with your car, then again given the right condition maybe less!! fancy the drag day at York
best i ever managed was 12.1 in the s2000 111mph terminal, i almost run a good 11's until i backed off at the wrong timing beam (1/8 instead of 1/4, note to self never look across at the opposition)
still managed to run a 12.1 that time.

Chris
Just had a look at those graphs above which are interesting. There are a couple of factors they don't take into consideration though which may be
a bigger factor for a seven than most, which are aerodynamic drag and outright power.
I suspect most of those figures are taken from fast road / drag cars in the states which maybe have 3-500bhp but weight over a ton. Having 300bhp/ton
in a 1ton car will give different acceleration characteristics to having 300bhp/ton in a half ton car because at higher speeds, particularly with
barn-door aero, outright power has more of an influence on acceleration than power to weight.
I suspect that most sevens will perform slower 1/4 mile times than predicted by their power/weight and/or 0-60 time, because by the time we hit
90-100, the combination of low outright power and brick-like aerodynamic properties are already having a big effect on the rate of acceleration,
whereas if you were in a comparatively slippery road car with say 500bhp that weighed 1.5ton, you'd still be accelerating almost as hard as you
were at 50mph.
