Challenge! 13's in the Quarter with 30 MPG City?

30 mpg city?? Maybe highway.

my fiend in his 04 gto gets high 20's with exhaust and a intake. I tuned it with HP tuners. you have to flash the long term fuel tables and re-right them. they are EXTREMELY rich from factory.
 
I somewhat remember Rod ,maybe Steve?, Millen making a N2O kit for an Escort GT. IIRC it outran Mustangs of that era (mid 80z?).

I believe it was tied into the computer to prevent N2O coming on in first and below a certian RPM.

Here is a newer verision of the same idea that went high 13z and only cost $19.95 :mrgreen: : http://www.aces.edu/~parmega/articles/neon/

I checked old Car & Driver and they list a 1998 getting 29 city. With a few minor tweaks 30 would be easy.

Just find a a/c car and it will meet all your goals.

VW Turbo diesel??
Yes , i do not know if Volkswagen ever sold that engine in the USA in the Rabbit or Jetta !? It is the most sold car engine combination over here....

They did sell it in the US, but many here may not be aware of it. I actually was trying to find one cheap, but they are in such high demand that it simply is not possible. In the US, Diesel fuel is more expensive than gasoline because it is taxed at a higher rate. US emissions laws are more concerned with NOX emissions while EU laws are concerned with CO2. Since diesel engines are naturally higher emitters of NOX and particulates, the government makes it very hard to get one approved here. In the EU, you can quickly make back the price premium for a diesel with the lower fuel usage and the lower cost of diesel. In the US, not so much. Also, VW products have a reputation for poor quality and high prices in the US, so they are not very popular with consumers. The diesels do have a niche following though, and since they are hard to find they command a premium on the used market. It's actually sad that diesel is seen as such a pariah in the US as I feel it is a far better technology than hybrids for the long haul. Like I said, I would actually purchase a small diesel car or truck if one were available in my price range. Sadly, the only ones I can afford are $10,000+ and have over 100,000 miles on them. The engine may last indefinitely, but the rest of the VW it is attached to won't. Last I heard, Mahindra (India) was going to bring a small diesel pickup to the US, maybe it will be cheap enough to replace my current Nissan with 330,000 miles on it.
 
Something with a 3.6 vvt engine. They are suprisingly powerful and fuel efficient. Or the ever popular 2.4 Ecotec
 
I' m sure you are on all unto the right path with a programable electronic engine management system, 5 or 6 speed manual overdrive transmission, turbo and a 4 cylinder. The make of the engine and drivetrain I guess could be debated forever.

Has any body actually done 13's in a g body and gotten say 20 plus mpg without poweradders. I'd be curious to hear the set ups.
 
Do you mean 20 MPG city or highway? Many of our cars can do 20mpg highway and 13's, but I would think that very few hit that in the city. My car does around 16-17 city by my best guesstimate (and 13's with posi and traction, again, a educated guess). I have yet to add the lockup kit for the converter or swap in a 5 speed, so I will see if i can hit it in mine when money allows. The best city MPG I ever had in a car was 32 in a 5 speed 98 Sentra XE with a 115 hp, 1.6 liter 4. I don't know the highway on it as it only ever saw city, but the 95 Sentra I had with an auto and the same engine got 55mpg highway and 26 city. Both those cars were pretty slow and took 10-12 seconds to hit 60, but they weighed 2350lbs too.

The sad thing is that my Cutlass is actually about as good on gas in the city as my 4 cylinder truck now. The truck still runs fine, and has no codes that explain it, but the fuel economy has really gone in the sh*tter lately. I am thinking it finally is just getting old and there is not much I can do cheaply to bring it back to the 24mpg city it got when new. 330,000 miles of pizza delivery can't have done it any favors.

As for my combo, it's a basic 355 Chevy with Ok heads, 9.5:1 compression, a Quadrajet, performer intake, XE 262 cam, small tube headers, TH 200 4R trans, and a 3.23 gear. The car was planned with a set of parameters which included fuel economy goals, drivaeability, and running low 14's to high 13's. It was planned out as a pizza delivery car, so it could not be too radical. As for the performance, it makes around 350hp and 410-425 ft/lbs depending on if you go by the sim or the similar engine built by Comp Cams to demo this cam. The real treat is that it makes 400+ ft/lbs from 2,000 RPM until around 5,000 RPM, so it requires very little throttle to get it going. The Quadrajet also adds to the excellent low speed throttle response too as the tiny primaries let the idle be lower and give it a hair trigger throttle due to the strong vacuum signal. The lower idle speed also contributes to better fuel economy than a square flange carb can give. If I were to plan it again today, it would get a small LS engine like a 4.9 or 5.3 instead of the GEN I SBC, and I would run it off a Megasquirt ECU instead of a carburetor. Why go with the smaller engines? The LS is a very efficient design, and produces very good power to displacement ratio numbers. Since 350hp is all that is needed, a smaller engine is fine. Plus, as fuel economy is an equal part of the equation, a smaller engine naturally uses less fuel than a larger one of the same family, all else being equal. After all, what good is a fast car if you can't afford the gas to actually drive it? Also, aerodynamics do not play a huge role in low speed driving, otherwise I would have built something different.
 
On the subject of fuel economy, I was doing my slog through Top Gear's website and came across a new VW concept car that is ready for production. It's small, and a little odd, bit it gets-are you ready?- 189MPG!!!! It is a 2 cylinder diesel with 800cc of displacement, and yes it is a hybrid. Ugly or not, if it were cheap it would make for an awesome delivery car. http://www.topgear.com/uk/car-news/vw-l1-concept-2009-09-14
 
with junkyard parts. can i retune the ecu? if i can retune an ecu this is simple

1.6 litre honda, plus crx HF stock manifold + dsm 14b or 16g turbo + dsm intercooler/ injectors
chip the ecu and hello 13's, pretty simply. along with 35 mpg city, and still 40 on the highway
