What are the differences... preformance wise..... pros vs cons.
Thanks

I belive Spit9 can turn better Spit 8 climb better and hold E better and Faster. Also more fuel time. Roll rates the same.

no difference they are both "dweeb-ish" :p

You talking AH or the real deal?
In AH we have the Spitfire FIX with the universal wing. That's the early Spit IX with 2 20mm and 4 303s. The model we have has the tropical filter under the nose. It's engined with the Merlin 61 which was optimized for higher altitude work. The AH Spit IX has 85 gallons internal fuel as well as an ability to carry drop tanks. It also has the smaller rounded rudder and the full span ailerons.
The AH Spit is an LFVIII has a retractable tail wheel, short span ailerons, tropical filter, taller pointed broad chord rudder, wing fuel tanks in the leading edge that gave it more range then the IX and the ability to carry DTs. It has the Merlin 66 which was optimized for better performance at a lower height band. IT also has the universal wing with 2 20mm and 4 303 mgs.
Opinions will differ but the VIII should be the better bird down low and the IX better up high. In real life either could have the Merlin 66 or the Merlin 61. or even the Merlin 70 for high alt ops.
Right now I prefer the VIII over the IX but right after they came out the IX seemed better to me. I prefer either one of those over the XVI.
-
The VIII had smaller ailerons with better mountings to eliminate flutter at very high speeds, and was intended also to improve roll rate, although I do not know if that was the case.
There were some VIII's with extended wignspans also, but ours not.
-
The Spitfire Mk VIII was the most refined Merlin Spitfire.
As to how it compares to the Spitfire Mk IX in AH, well, it is generally better. The Spitfire Mk IX turns a bit better due to lighter weight and is better over 22,000ft or so. Below that the Spitfire Mk VIII is faster, climbs better and has greater fuel endurance.
Handling wise, the Spitfire Mk VIII is my farvotie Spitfire in AH.
-
The more I look at the VIII speed curves the more I think something doesn't look right.
VIII was a better performer all round compared to the IX at low alts, yet the speed curves don't reflect this.
If they are correct, apart from an increased climb I can't see why they bothered with the Merlin 66.
Spit VIII level speed at all up weight 7,770lbs @18lbs boost
Feet, Speed
0, 338
2800, 349
9,000, 374
12,000, 371
14000, 380
20200, 405
Seems like the whole curve needs moving up at least 10 mph.
-
338 is 17mph faster on the deck than the Merlin 61 Spitfire F.Mk IX's 321mph in AH.
-
No, that would make it a spit16 :P
The 16 in AH is only about 10mph faster than the 8, in most circumstances (going from memory here).
EDIT:
Offline speed tests, full gas no DT
IX
319 (faster than I recall)
VIII
337
XVI
343
XIV
359
Making the spit8 10mph faster along the entire curve would make it BETTER than the already uber-leet spi16. The 8 is already good enough, and I wager most folks agree :)

Only by those that think certain planes are "dweebish". Those people can be easily identified by posts such as yours and are usually the result from the lack of ability to fight against the "dweebish" planes. Basically, you're the dweeb and not the Spitfire driver.

Sorry - I meant the curve shown in the comparison on the
http://www.gonzoville.com/ahcharts/index.php?p1=spit8&p2=spit9
webpage.
Your tests show it is correct in AH, was questioning the data in the comparison.
-
My bad, I mis-read what you meant!
-
Looking at the speed curve, on that page, the 8 is too high. It's listed as about 345 or so mph on the deck, when it's 10mph slower. I think the curve needs to be moved down, not up :aok
-
Oh FYI there were also Spit VIII's with the Merlin 70.
Not sure if those were the expanded winged ones or more.
A performance quote I have for VIII's operating in the trop - India, - is top speed 420 mph and a ROC from start to 20K in 5 minutes.
The measured specs I have are a tad lower - but good.

Merlin 70 ones generally got the extended tips, BUT as with clipped wings it's a crap shoot.
Wouldn't surprise me to find pics of the same aircraft at different time periods with different tips.
Good e.g is the HF VII's, by D-Day they had been refitted with standard tips. Pic's of both exist.
Seems to be the later on the war, the rarer extended tips became due to the air war for the RAF moving to much lower alts, conversely clipping became more common.

Disclaimer: Not a flame, just a question...
Are the Spits in the game generally porked a little? I've been reading up on them and seeing things like 18" of boost instead of 15" for the IX. I've seen some with Spit XIV using 25" boost. Also, I've seen stats for the V, VIII, IX, and XIV that are showing uber rates of climb. Like the XIV showing around 5000 fpm down low. This was all British test data I found on the web. Some dated as soon as 1943 for the IX with a 4200 fpm rate of climb. Ours doesn't even approach that.

We have -
12lbs for the Ia
12lbs for the V
15lbs for the F IX
18lbs everthing else.
We used to have the 16lbs Vc
Max used on the Ia was 12lbs - no change (just prior to B.o.B.)
Max used on the VIII was 18lbs - no change (from manufacture mid 1943)
Max used on the LF IXc was from May 1944 - 25lbs
Max used on XVI was 25lbs - from Dec 1944, BUT as the XVI is also the LF IXe would be 25lbs from July 1944.
Max used on the XIV was from July 1944 - 21lbs
When you say IX, you have to draw the difference between the F IX, LF IX and HF IX.
Guess they feel any max boosted Spits wouldn't be fair.

Yea the 5 min of supa boost is just way to unbalancing. :rolleyes: :rolleyes:

Thanks Kev...
I knew you could clear that up for me...

Note one thing on the VIII. It has much more internal fuel. So, with the same gallons, the performance differences will be more in it's favour.
