I was reading about this Holley Stealth Ram back in 2003 when it was new on the market. Holley made a "mini ram" intake plenum for clearance issues if you used the stock hood. Basically, the Holley Stealth Ram was an LT1 design that was designed for the 3rd gen Camaro Firebird. Back in 2002-03, dropping an LT1 or LT4 was the go-to drop in motor for a 3rd gen Camaro Firebird
The exact opposite of what you said is true. The miniram was TPI's Inc. answer to the LT1 for the TPI motor in the mid 1990's. The stealthram is a completely different design by Holley, its a tunnel ram intake borrowed from the muscle car era that basically shifts the max RPM range from 4,500 (TPI design) and moves it out closer to 6,500. With the proper heads/cam the stealthram would make a third gen slightly faster than an LS1 equipped car at the time. Times have changed and doing an LS swap with a cheap turbo has become the swap of choice now due to quantity of LSx engines/parts and reliability of the LS series of motors. "Today you learned".
@@steve069 Actually, I've already known about the popular LS engine swap of today as that has been popular for over 15 years now, and yes, the design of the Stealthram is patterned after the tunnel ram intake, however I compared the Stealthram and Miniram to the stock production LT1 intake because it looked similar and eliminated the runners of the stock TPI, which increased cfm which in turned increased hp and torque. The Stealthram does incorporate the runner design, they're just designed "straight down" into the plenum like the tunnel ram. Part of the reason why the TPI intake was so restrictive is because of the spider legged design of the runners. The shortest point to a destination is a straight line, and by the runners of the TPI being sharply curved, the airflow was restricted, inhibiting airflow straight into the engine, besides the size of the runners being small. The Miniram is designed more like the stock LT1, and when I get another IROC-Z and modify it, I think I still wanna go with the 4th gen Camaro LT1 with a miniram intake/heads/cam, etc, simply because the 4th gen Camaro LTI and LT4 engine is overlooked now. Those engines were the next engines after the L98, and they're more closer to that time era. I always loved the sound of an LT1/LT4 engine with long tube headers, y-pipe, and 80 series Flowmaster exhaust crossflow muffler. It sounded like a beefier L98, but of course the LS engines are the way to go and are a lil more powerful. I love the LS swap, I wanna get my hands on an LS3 or LS7 and dual turbo that shit. Shit, what I really want is that C5R LS6 engine that came in those GMMG/4th gen Camaro ZL1's!
@Hans-Olof Olsson I'm using the caliper perfectly fine. Some of the ports aren't perfectly round, so I could move the caliper around to find the widest area, but what would be the point?
The answer is to use a super ram or stealth ram. I have a TPIS base with the Edelbrock runners and a ported plenum. Its still never enough. Still, if you cant machine through the entire tube, youre not going to do much.
I am aim in the process of restoring my 85 vette, I plan on buying a big mouth vortecintake, and slp runners and my stock plenum with 58 mm TB, 1-5/8 HEADERS and installing on a 355 with a 385 hP & 416 Tq tHIS IS A CARBERATED CRATE MOTOR. bUT i PLANE ON USING MY TPI SETUP, I would like to get a Price frome you on doing all 3 PARTS , COULD YOU SEND ME A QUOTE PLEASE.
how much cc's can the best tpi runners carry?? the holes are still very small even on your biggest runners on this video imo. I want to build a 383 stroker with the afr vortec heads. the ports are 2.320" H x 1.297" W 190cc. It will be used on a 1989 camaro IROC Tribute replica nascar build. Id like to know what you think. You sound like the expert at the tpi info. Should i use the accel super ram setup? Thanks
REDZ28won They definitely look the best, but the edelbrock runners are just as good when it comes to flow. The inside surface is very nicely cast too. Consistent size all the way through. They're the best of the cast runners.
what about the mini ram intakes? I understand that ported and after market is great for street and drag, but what about ram intakes? Seems like those should also be popular.
Arizona Speed and Marine are the Best TPI runners!
AMEN!!! stock look too!! i have a set i got cheap from a guy on a forum site
polished them they look awesome!!

Love me some old tpi stuff. Good vid
@bigdog7865 I'm sorry a wasn't able to entertain you, but honestly it wasn't intended to be entertaining. Take some Ritalin and watch my other videos.

How much of an improvement do you see with the SLP runners vs stock runners?

@poopdawg2301 Honestly it probably was. I had a wicked fucking cold.
@Dennis Berryhill
was the snot that dripped at 6:19?
poopdawg2301 yep!!!! boogers!!!!
Would it pass smog to put it on a 82 Corvette 350
SLP bolted on a mostly stock L98 what kind of power gains it would produce?
5-10 hp at most and where the horsepower is gained it will be lost somewhere else in the powerband due to the TPI design.
Would these work on am LT1? Need an intake with longer runners.
Adam Weaver , No, different bolt pattern/spacing.
@@DarinDochterman okay thanks.
SLP has never impressed my, I use TPIs miniram.
This video is so informative, but it's incredibly boring. You could have done both parts in about three minutes.
how much do yo charge, for intake & runners. looking to do some work on 89 iroc z, but not go over board. about 390 H.P. at flywheel.
hmmr60
I’m not offering porting services anymore, sorry. Thanks for your interest though.
That's about as constructive as criticism can get, your attitude doesn't have to be as poor as your editing skills.
