300 HP at the wheels in a civic is going to be hard to beat if he hooks up.

One of those weigh...2500 lbs or so & figure 2700 "race" weight unless he gutted it.

So that is a LOW 12 sec ride if he has all his ducks in a row.

Have a friend that had a 13.0 sec. 340 E Body. Best et and mph was with a 750 DP on a LD340 intake.

That said, there is probably something else amiss for the AFB to be a full second slower than the 750 IMO.

Nope.... 750DP w/ 28 squirtters, 72-78's and It'll get it done.

I disagree, not for any mild 360, its just too much carb

---

My mild 340 swinger had one of those Carter 625 comp carbs on it. ran fine. I had a 750HP on the shelf. Drop it on w/ 28's and light jetting and it ran killer. went form 14.20 to 13.80 and had zero effect on mpg or drivability. Holley 750's are VERY easy to tune and work on almosty every application. He has more cubes more cam and btter heads. A 750D tuned will work great. Now a 70 will too but you can't swing a dead cat at a swap met and not hit a 750 for sale.

I doubt it. We shall see. My prediction is I beat him by half a second. I have doubts just putting a turbo on a honda civic makes a low 12s car. He's got alot more things that have to go right than I do. My car runs good and is consistant. He's still working the bugs out of his and he has to drive a stick shift and he better get it right out of the hole and not miss a shift!

I have this same question but don't want to hijack the post. ... but might try anyway....



440, 9.2:1 compression, Eddy heads, Performer RPM, Lunati 60303 cam, full length headers w/ full 2.5" exhaust.

I bought a Holley 750 (80508S) when I had a stock 440.

Now I think I need an 850.

But it is street driven and I've always been under the assumption that the smaller carb helps street manners.

Smaller carbs have better throttle response. Most daily driving is done with part throttle. So yeah they would be better for that.

And what is the BESTest ferr dat ? ... the Plastic-Fantastic ...

DON'T be a Berry-Bum ... join the ThermoSquad !

Yeah I agree, but it runs, starts , idles and pulls normal. No surging like it's lean or anything of that nature. I just doubt that the motor is starving that bad on a 625cfm carb. Gota be something to it.

13.80s is all you got out of that Swinger, Any holley DPer is easy to tune, that has nothing to do with it, If your happy running high 13s with your 750dp in your Swinger thats cool, i'll take running 12.5s with a 650dp on a mild 360 in my Swinger .

Good luck either way, but if this guy does his homework & makes a clean pass you'll have a race on your hands, I hope you win, just don't under estimate these Civics, I know the mild ones around at our track will eat you for lunch, especially if you don't run faster then a 13.0

If its a stock engine internally enough boost to make any power will turn it into a grenade.

Not neccessarily. They don't need much to make them move, good clutch set-up & axles/sticky tires/exhaust ect. & they can run 12s all day on a small boost. Heres a link, notice how fast the Neon runs with stock internals, & the weight too, they weigh about like a civic.

NOW, look at the HP & weight of this civic, its not insane by any means, look at the ET & MPH, not trying to burst bubbles here, just proving a point on reality, i've aslso includeing a Neon, yeah & thats a Mopar.

Yeah my only hope is to get a good jump off the line and hope he blows the tires off of it. If it's close by half track im gonna be seeing his tail lights I'm sure. He had this new computer installed and they dyno'd it at 300hp. I'm hoping my 4:30 gears, suregrip and 10.5 inch micky slicks will work together that night!



I'm just going off what he said the car was making, it could be less as only the kid REALY knows.
Don't take my posts as suport for the ricer. I just don't think it is a good idea to blow the car off as a missmatch of parts & a easy win.

Yeah but thats an SRT-4 engine, which came with a turbo. I dont know what a civic has for a compression ratio but i'm sure its at least 9.5:1. We'll say that maybe it will take 7 lbs of boost safely, that might make 275 to the crank as a best cast scenario, depending on what engine they started with, so we're talking more like 225 to the wheels, not 300.

Civics are not only the butt end of our jokes, they are the butt end of jokes from the tuner crowd too, and for good reason. You can not make them fast and hold up without spending insane amounts of money. I know guys who spent 8K on an engine to run 13.50s in a 2600 lb car. Can you make them fast? Yes. But you will spend way more than you would to make a better car as fast.

The guys dropping 8K on an engine to run 13.50s could easily have bought an LT1 or LS1 GM product and done a gear swap and run faster, with more potential to improve. They also could have bought a car that came with a turbo, like a WRX, and just done bolt ons and cranked up the boost. I know the tuner cars are very capable from working on them. You can make them VERY fast. Hondas are not tuner cars though, they are just cars. With the cost involved with making them run and hold up its like guys are removing the valve cover and literally pouring money into the engines. And lets not forget, to make them really run you have to get an engine all built up to take the boost, then spend a few thousand to turbo it.

Back on topic do whatever makes it fastest. If you can't tune the Carter to come close to the times the Holley makes it run then the answer is no you don't.

Who are your kidden, they don't sink any more into there cars then we do, but obviously you must be an exspert on imports ..
