Hood clearance problem. help needed

evo or sti? rice?o No: i dont know what your talking about evos and sti's are not rice im sure they can be riced out but they are not rice.

maybe its just cuz im younger that i like the newer cars and muscle cars but maybe im the only one that is diverse instead of only old muscle.

dont get me wrong though i LOVE muscle cars i drive a 71 skylark custom but get your facts straight before you start saying something is rice.

 

Mitsu.....Suby...Made in Japan...Japan=rice...understand now?? My step son has a WRX and I have done alot of modding to it..Fast...yes, American...no Still a Japanese car and Japanese cars have been referred to as rice cars probably longer than you have been around. Not trying to be smart..just stating facts.. I could own a Evo or WRX so I have no hate toward them..

 

maybe our def. of rice is different when i think of rice i think of a cheap car that is modded only for appearance and is tastelessly modded in all aspects except for performance.

 

Then we will just have to agree to disagree then...It's all good, no harm intended or taken from me. I have seen some WRX'S run 9's and 10's at the WRX day they have every year at our race track and fully know their capability. I understanding your definition of ricer as well..The ricers you refer to are called scrap cans here..All muffler and wings and absolutely no performance..

 

haha got cha agree to disagree :thumbsup:

 

Your a ricer if your exhaust tip is larger than your cylinder bore.

 

I like this i will b using it.

tnx for the update, and good to hear the SPX is working great!

Can't wait, until the new engine is shipped, must be a big difference with our all iron 464 stage 1 engine, with S-divider intake.
The old engine performed well.
But the new engine has all the new stuff in and on it alu heads fully ported roller rockers, H-beams, better pistons, very strong bracket cam TA_510.
SP2 intake ported matched to the heads, PROFORM 950CFM carb,etc etc.

So I think it will scare the pants off me the first few times I launch it at WOT.:beers2:

 

You know I hate to bring reality back into the scene but I wouldn't get my hopes up too much on that kind of performance gain. Not saying that you won't pick something up, depends on your combination, but picking 3 tenths in the 1/8th for an intake change especially when you say it was mostly in the 60' times doesn't fit. That intake generally will help on the top end not the bottom.
Your MPH would be a more accurate indicator of what happened.
If you look at it realistically you have to realize that something else changed that would have helped that much. Did you forget that you had a rag in the old air cleaner assembly?o No:
Spinning your tires more on a road in front of your house doesn't count for much and maybe you're spinning less at the track because you lost a little bottom end with the single plane and the tires could actually hook up better thereby giving you better 60's.
Was there a weather difference? How about the track prep? Is that the same carb you used before?
What is the et slip breakdown between your best run before and after the intake change? That could hold some important info.
Of course if you change from an S-Divider to just about anything else that could be different and may explain everything.
Not trying to rain on your parade just looking for some good scientific testing. Faster is good, knowing why you went faster is better.

 

Yeah, nothing says ricer like an aggressive hood scoop. Hemi Darts, 6-pack Roadrunners and Stage 2 buicks......ou:

 

Big difference between the Mopar hood scoops...(Massive, bad assed,wild looking) compared to the small unattractive Stage 2 scoop..I'll stick with my Chevelle looking hood..

 

Yeah,I agree, its too small and unassuming. But I would no sooner put a 6 pack scoop on my Buick as I would a cowl hood. But thats just me.

 

That's what makes our hobby interesting..We can do modifications to our cars and even if we don't agree with some mods,we still enjoy and respect others cars..:TU:

 

Actually, I hate to admit it now.....but I thought about using a cowl hood on my car. I still might. The stage2 scoop destroys the sleeper look I liked about my car before. However, now I'm thinking SixPack scoop..... they do look badass.
:laugh:

 

Wow, interesting comments. Guess you were there and read the time slips and I didn't, or I just am not intelligent enough to read one.

Same track, same altitude, same temperature, different days. Our car does NOT spin at the track, never has. Suspension works. Carb change had been done a few races earlier. No other changes made.
Picked up almost 2 tenths on 60' time, and 1/8th mile ET was almost 3 tenths faster than our best previous pass ever with the car. And it was consistant before and after. We race this car, not just go make a pass every once in a while. MPH was same as previous, did not pick up anything there.

Bottom line in my humble opinion is, the 464 could breath with the new intake, and pulled better from idle to shift point. It was very happy with the change. People wanted to know, so I shared the info.

Sorry you don't believe me.
Mark.

 

Mark, nobody is calling you a liar but Mike does make some good points to consider.

Regarding hood clearance. I went to a SP-1 from a B4B and the height difference I seem to remember was about 1 3/4", anybody know if the SPX is taller than the SP-1...I was thinking it was, slightly?

I'm was using a 1.5" drop base, Q-Jet, .25" gasket, a 3" filter and it all just barely fit under the stock `72 Skylark hood.

 

For what it's worth, TA states the SP1 and SPX are 1.5" taller than stock, and SP2 is 2" taller.

Mark, I never said you were lying nor did I infer you did or that you read the time slip wrong. Why would I question that you picked up 3 tenths? You said you did. I believe you. I WAS NOT there and that is why I was wondering about the circumstances when you ran. You apparently do race a lot and therefore you know your car the best so you are most suited to answer the questions I had. Maybe you thought I was serious about the rag? If so I'm sorry it sounded harsh.

I have been racing a while now though and when I hear more than a couple of tenths/mph for any one product I start to get skeptical about what caused the improvement. You know what Im talking about. Somebody will say they picked up sec with a 1 carb spacer but they forgot about the miss they had before and the new MSD ignition, plugs, plug wires, and recurved dist. they also changed. Remember the old camshaft ads that used to tout their 70 hp increase but in the fine print they mention that they went from a completely stock engine to their wonder-cam plus headers, intake and a carb change? Theres only a few items off hand that I can think of that wouldnt cause me to wonder about such great results, like stock vs. ported heads, turbos/superchargers/nitrous, high stall converters and that type of equipment.

Your reply answered some of the questions I had. If I had been asked the same questions I would have replied:

Yes Im not sure exactly why it picked up 3 tenths in an 1/8 and mostly in the 60 to boot but Ill take it. You cant argue with results. With an apparent extra 30 ft lbs of torque at the bottom end from an intake of this type I wouldve expected at least a like amount of extra MPH especially because it felt stronger throughout the rpm range. Why it didnt pick up any MPH has me wondering. You know, trap speed is the best indicator of an actual HP increase. The weather and track conditions were identical on the before and after so that shouldnt have been a factor. Traction seemed to be great as usual. Maybe the carb I have on was on the rich side with the (fill in the blank) intake I had on and now it is running in the sweet spot? Maybe theres a torque peak somewhere down low because of the runner length and it hit my torque converter just right? Im not really sure. Anyway it happened Ill take the 3 tenths. I cant say everybody would pick up that much performance with an intake swap like this but like they say Your results may vary.


Sorry to highjack your thread but you put some information out there that got my interest because Im considering an intake change and I decided to ask questions. I was only trying to find out if you could shed some light on why you had such a great ET improvement with no MPH increase.

 

My response was a little harsh also, so I apalogize. I felt like you were saying there was no way I was being honest with the people here.

My son corrected me, we did pick up 2mph. But we are already hitting 90mph in the 1/8th mile. It is a highway driven car, so we have never had great 60' times, but he can get the front tires off the ground.

As to any possible other changes. None that I am aware of. Not even fresh spark plugs or oil. Through the course of the racing season last year, we were able to shave off a full second ET in the 1/8th mile from first pass to last. Not a bad year. I don't expect that this year.

As for the hood scoops. I like almost all of them, except the pro stock style. We would go to a stage 2 if we added one to this car, but probably will keep the GS hood.
And BigNasty, we hope our new race car build looks like yours this year. We will have a flat hood on it since the twin turbo won't need hood space.
