I am not clear. Are you happy with the 110mph trap speed in hot air?

I am looking forward to Brian putting a FIRST on his 406. Let's see this awesome intake in action.

For me I would rather have 450rwhp/450rwtq, then 390rwhp/490rwtq.

Our Corvettes are light enough. If it was a truck then I could use the extra torque.

 

What do you think hes concerned about ET or mph?
What #s it makes is irrelevant at that point.
Hes got an honest 11 sec ride in decent air with a LTR setup, sounds good to me.
If he had to run it to 9 or shifted at 4k the ET is the ET.
Dont know why everyone is obsessed with high rpm. Its one thing if you can run it up there but another if you HAVE to in order to make power.

Huh? lol


Know youre excited about your motor Ricky but get that thing down the track before judging others.

 

What intake are you running ? Lets see some time slips ..... .....

 

oh ronny. its all in good fun. relax! i have no clue if he is concerned about mph or e.t. really at the end of the day it doesnt matter.

ill give you a call you bald midget.

 

You answered a question with a question. I am running a stock TPI, but it's heavily ported.

 

I like the information trickling out..... I think the 400 rwhp link to the F-body guys is actually pretty impressive. And I think they were able to climb up and above 6000 rpm to do it..... for the vast majority of us racing late model fuel injected cars, yet, maintaining excellent street manners, that is definitely a viable option. Although, I still want to see some et's out of them..... but, if their car is working, 400 rwhp is good for easy 118 mph trap speeds in a full weight C4..... thats mid to low 11 second et's and very respectable in my opinion.

This tells us, rpm and the restriction of the long tube runner intakes isn't just about length, but also about pure airflow..... which we kind of knew from other applications. I think those python runners are working.... but, for me personally, I'd like to see some more running them before I come to my own personal conclusion. Nothing proves a point better than a nice looking timeslip.

I do agree with Ricky, the 409 cubic inch motor only running 12.16 @ 110 mph is considerably slow in today's day and age. But, the poster did say he had other issues.... so I think we should cut him some slack. Besides, he's out racing and you can't fault that ! I'm sure he'll get it worked out in due time.

 

I sent a pm to C409 because I felt bad. I think the 12.16 is still decent e.t. but I was curious if he was happy with the 110 mph? Usually our cars with high tq and lower hp will trap good e.t., but not mph. Too each there own. I personally am not after e.t. but mph. MPH imo shows how powerful the car is, and therefore more enjoyable for moi.

I was just comparing the mph with a friend who has a 96 LT4 car with full exhaust that traps around the same mph.

When my 88 engine was stock it had 240rwhp, and 330rwtq, and my best e.t. was 13.5's. A few people were suprised that I was able to achieve that with a manual car with only 240rwhp, but when I told them what the tq was it was more understandable. My mph was very low at a 101.8 if I remember correctly.

I will have to go check out these 400 rwhp threads that Beach is talking about it.

 

IMO the stock intake on a LT1 is one of the better features that it came with. We have seen better designed heads for the motor, I just wish someone would come up with a better block for the motor.
But to anyone still developing products for the LT1.

 

My car has trapped 119 mph with the stock intake and stock shortblock. We almost had (Dart) a better block.

 

It's official! LTx owners don't see any advantage in trading 10% more power up to 5.5k rpms (in exchange for 6k+ power).

Moderator, you may close this thread. There are no forward thinkers here! (Especially owners of stock 350 units).

gp

P.S. Of course we know big cube guys that trap 140mph+ will [go out of there way to] scoff at anything -- no surprise there.

 

Greg, sorry to upset you, I just cant see investing $1,000.00 for the intake. If I had a L98 then maybe so. But for me even if there is a gain, it would be small. you can see my best in my signature below. and that is with a stock shortblock. The 10 percent more power up to 5500, well I doubt, and just for your information, the best run on my car was shifting at 5800 rpms.
But again, I am glad to see manufactures still producing LT1 parts.

 

Well I'm going to post it up for y'all. These are F-Body cars. Our e.t's may be a little slower because of weight and better air intake flow but we can still produce good power with the old TPI's. Please don't count them out.

I like to know what kind of HP some of you are making with Super Rams and the cams are being used. Any Dyno results? I doubt it.

 

Actually a lot of them here do, plenty of guys drag their cars here.

Thats like saying XXX guys will never show their time slips. You have those dont you?

 

Not upset...just checking out of this thread. I brought the news to LTx guys and there's too much you-go-first/negativity in response. Even from people who don't give a crap about getting a new intake. It's intake bashing IMO.

Go back and reread BADSS's post. He shifted the FIRST at 56-5800 also. He, and others, have also compared the FIRST to short-runner intakes. It definitely jacks more reversion. The strength of those waves is in the 7-10% range.

The more power and the higher rpms you run, the less this intake will/should interest you. For guys running around town, seldom/never going to the track, there's some advantage to be gained -- especially if you're still stock (or near it). There are also guys who just like torque...the kind of car that hits fast/hard. I'm one of them.

The difference is I don't jump in threads about other options (than mine), brag about my accomplishment (torque), and say "Why would anyone be interested in anything else?" --or-- "I already have a great intake from the factory!". It's a worthless post IMO.

This thread has gone on what, 7 pages? I've said what I have to contribute. Can't think of anything else to add except...

If I wasn't considering the possibility that I might have to resell my car (sooner than I'd like), I would have picked the FIRST...hands-down. 10-yrs ago, I'd have picked it in a heartbeat. Because I can clearly see the advantage for a sub-5.5k street car -- especially if it were a stick.

When I set out to do my build 3yrs ago, I had to push beyond concerns of AFR oil-runback issues, AFR core-shift concerns, Vette-Tech header nightmares, never having ported an intake, etc..... While you can say I wasn't the first guy to jump on those options, I picked/bought them with a lot of doubt in my mind. But, I'm happy with the result and my trust in the dynamics of each part.

There are too many people who say "You go first, I wanna see more.". Those kind of posts are boring to me. They just don't contribute anything. Neither is the smack-talk and "I love my car" stuff either.

Blah, blah, blah.....

 

Well said!!

 

Nope!
We show and tell everything. We have nothing to hide. Go back to the videos. Very very very few people will make a video like ours the show everything.

 

???

Exact opposite actually.... most everybody here for the last dozen years has shared information on their quest for acceleration. Granted, its not organized in a single thread, it is instead spread out over hundreds of threads, but the information is all there, you just have to look for it. However, the cliff note version of much of the information is in the timeslip sticky at the top of the forum.

You'll probably find more timeslips than dyno information here on this forum. Dyno's are for girls. j/k

 

Greg, after reading your post.... I felt compelled to go back and re-read your original thread starting post....

Your post was:

"Seems like I remember reading they were in the process of developing the LT option. But today, when I looked at their website, it's listed as available.

Kinda surprised I haven't seen a thread on this. OTOH, you don't see many FIRST threads for the L98 option either. "

To me, and I am sure others, it looks like you are looking for feedback from fellow forum members on why you do not see threads on the First Intake system..... It appears you have received this considering it looks like a few LT-1 owners chimed in and told you why. About par for the course for automotive message forums..... you get different opinions and why its important. I don't think that should surprise you or even disappoint you, or at least I hope it doesn't.

 

Tons of people show off thier dynos, which is nice. Any forum or youtube is full of them.
Now lets see how they run down the track;threads here full of time slips from 15 sec crossfires to 7 sec boosted C4s

Probably never dyno mine but it will see some track action before the year is out. Whatever floats ones boat.

 

It doesn't. I suspect most (if not all) LTx owners would never consider "going back" to a long-tube setup thinking the LT intake was progress...a reason to dump TPIs and never look back. Anytime someone buys newer technology, they inherently believe nothing could have been better with what's obsolete.

For everyone building hyper-6k setups in quest of higher HP, anything resembling a long-tube setup would be an aboration. I still think there could be LTx owners looking for more sub 5k torque with a header/intake swap. Just as the SR was a middle-of-the-road intake for L98s, I think the FIRST could be so for LTx motors.

Since LTx owners would rarely, if ever, give a serious look at longtube solutions, (to me) it stands to reason the FIRST intake is an option easy to go unnoticed.

I don't care if/who buys one. My post was really more of a heads-up. And, re-thinking my original post, I'm not surprised no one has noticed this -- especially LT owners.

P.S....If there's one/two owners looking for an LS-length intake, a FIRST base combined with a modified runner setup (like 89TA is running), just might be worth considering. I'm not sure how else you could accomplish that w/o completely converting to an LS motor. (Also, I have no idea if a FIRST base is available as a stand-alone purchase.)
