My tuning guy has run every friken' intake and combo you could think of and he is not a fan of much of anything but a plastic intake really. He said that you gain a little going to a sheet metal but heat soak is just a killer and by the time your done your back to square one. Now if you have a combo your reving to the moon then have at it. Other then that a ported Fast 102 is hard to beat

 

Jesus Christ David, that is impressive.

I can't wait to see what your car cranks out with the Polluter. I think you have a solid 580-600rwhp car with stock heads and a Fast 102.

You saw what that stock exhaust Z06 did with your cam and it made 541/485 on a Super Flow. I would hope that an aftermarket X pipe and cat-back like the B&B Fusion would make 550+/495+. You know how mild my LS7 Polluter cam is compared to the Widow, the Punisher and the other big LS7 sticks out there. Yet it seems to still make the same power right there with those bigger cams.

When you think you'll be back on the road?

 

Common place? Really?? On a MUSTANG dyno?

 

How is Carlos's thread even comparable to a non E85/race gas engine build?

Carlos's own words: "The CR quenched is about 13.3 on this motor. PLUS, the cam revision now promotes slightly better cylinder pressure thus making the CR and better/more octane a marriage made in automotive heaven. "

You take ONE test result that shows no difference between a NEWLY DESIGNED ITB intake (ie: unproven or refined), compared to a well designed intake SYSTEM (Halltech) with a plastic intake manifold on a car with a raised static compression ratio with a mild cam running on e85 and use it as a basis for your position on ITBs?

Here is Jason at Katech saying his Kinsler was worth "45hp":

ITBs are not the end all be all of intakes, and they come with their own constraints (fitment, filtering, dbc in most cases, etc), but your argument against ITBs performance potential is weak at best...

There is a build that LGM did a few years ago with ~500ci and a plastic intake made close to 700rwhp on 100 octane iirc.

Tony Mamo's engine with a FAST and all of his attention to detail should be 650+ on a dj too.

I'm not saying you can't make great power out of a plastic intake, but you make it sound like these types of builds grow on trees and are "common place".

It's just not that easy to build a NA 650+rwhp engine that makes it's power on 93 octane with a hydraulic roller (ie: not peaking well past 7).

Why don't you "throw together" a Ls7 head, plastic or sheetmetal single tb intake, hydraulic roller engine that runs on 93 octane only that you think will dyno or perform at the track just as well as LPE403's setup with a similar drivetrain and show us all what's up.

You're dreaming...won't happen.

 

There are no words for this ITB......= More than just you everyday FAST & by the way ASK Tony would his engine make more power with A ITB this is FACT, Grow up FAST intake is USEless only if you like TQ I want and need HP & ITB will get TQ. Maybe U need or would like to come into My WORLD....My name is THANOS!

 

All you did was bring up a few other builds that have out dynoed lpe403?

600+rwhp is pretty common with ls7 stuff.

And most guys do it with 427inches

Lpe hadn't made 650 so why are you using it as a comparison?

Y'all want to compare track numbers? Because I have some. Thrown together ls7 in a 4000lb car. Anyone else have any?

 

Remember My NAME is THANOS ......AKA go find out what HE is! I'm' not RICH and IF I was.... could I will DUMB it DOWN for U...! ITB....! This ain't my engine and I AIN't KNOW hater!!!!!!! 408 close if not 700FWHP @ A/c...... HE got that covered and RUNNING by the way I have a LOT of Different Names as of NOW you can call me Mr ....DOS EQUIS = The Most interesting Man in the World .......This is this young man Thread...... I hope I can help,,,,,, and Remember my name Thanos.....Go look at what Happen to the Super FRIENDS....!

 

I will say there is more to a ITB than peak power.

I only have cathedral ports (one of the best cathedral ports) with my 455, but anyone who knows me knows how much time I spent on a Flow Bench with mine.

The 55mm Harrop was way weaker than expected. Only 283 cfm. Through porting and new throttle shafts designed we gained 44 cfm.





My throttle shaft was worth 12cfm alone.



As for the more to the ITB, they idle far better than a single TB. My car has virtually no lobe with a 254/260 .670/.670 110 cam at 750 rpm. This was my goal to make it sound stock on the street, pass emissions and run low 10s on a full weight car. My car is one of those turning cars, which is where the ITB truly shines. I was lapping a tight track 2.5 secs per lap faster than a GTR. This was with my motor wounded. This is why you see the LeMan cars with them. The throttle control and response is instant, allowing you to put all the power down.

Mine will eventually make 600ish, but I have not see lots of NA cars doing it at 6000rpm on real pump gas with compression ratios in the low 11s. There is "0" E85 in Canada, so I am set up for 93/94 octane and could likely use 91 too. It made 705 fwhp on a stingy dyno with old 1 7/8" headers that had no merge collector. I have 2" now with the merge.

I have seen and owned a mid 12:1 ratio 412 ci motor that ran on 94, was tuned rich and had low timing, ran 10s at 129-130 at 3800lbs. If you want I pictures of the pitted pistons too. It held up, but was not pretty. Not this time, it is a real world 11:2. Measure it myself.

I think the Kinsler is a work of art. You can not go wrong in my opinion with it.

Black on Black seems to know more than all of us though. The quoted thread on Vette forum it very high compression that needs high octane, not apples to apples. The best I have seen and believe is the Monte with the 427, as you can see it turns rpm to achieve the high number with a solid roller, I have faith in those numbers.

LPE and Stage 7 have a lot of hands experience too. Roberto's fab skills are top drawer.

 

If U were to do again,,,, Would you do it the same or would you go Generic?

 

You're hung up a dyno number. My "number" on this dyno will drag some asses.... I can make a 651 if you'd like....660, 70.... where's that DJ? Youre making apples and oranges comparisons to just about everything. Track #'s prove the combo...

 

I had a Fast on my 412LS2, and the Harrop crushes the Fast for handling and power combined.

I would not swap the ITB for anything.

 

I ain't got to LIE as they would say:'"This is the PROOF" or the TRUTH

 

Hey Dale...how many CFM are those threads worth? Gotta keep up with those LS7s

 

I'm seeing alot of talk about track numbers?

But does anyone here actually have any? Lol

Post the slip! Let's see the proof!!

Or are the stellar track results these cars put up just speculation Aswell?

 

Lpe post yours slips if that's all that matters! Let's not talk about dynos! Let's see how well that car has done on the track!

 

No more back pedaling or links to threads! Let's all start comparing trap speeds! Since that proves power! Everyone post Thier slips for Thier Killer 650rwhp ITB builds!

 

Or y'all can get out of my thread and have this argument somewhere else....I have the kinsler in my possession....that is the intake that will go on the engine....if you don't chew big red than **** you....Murica!

 

You have made a good call on that intake Briou. It will give you so much more than just a peak number, and you will very likely get that too.

-idle quality
-stealth
-throttle response, which improves handling more than most know.
-ability to use higher flowing heads

Will be a nice build!

 

They are one of the highest advertised Cathedrals. MAST 275s.

By advertising, they flow 372 cfm, by my bench they were 352cfm. This bench does seem to show consistently 18-20 cfm below advertised, she is a heart breaker. :-) It does show you what real gains you have though.

 

Thanks Rampant...I appreciate the comments....It should be a nice build indeed.

I tried to mount the l92 long block in the bay today and it looks like I have some work to do to get the mounts sitting correctly/drilled and bolted to the frame....Going to try to get some more work done on it tomorrow some time...I threw the intake on there just to see how it would look and it looks sick....I had some pics but accidentally deleted them....
