Hey everyone,

First, I would like to say hello. This is my first post at Thirdgen.org and I wanna say you guys run a great site. I have wanted to buy a '87 Camaro since I was 7 years old...and (long story short)...17 years later I finally did it! I've had my 87 IROC since September...

I just purchased a brand new accel superram set up (plenum, runners and manifold) that I plan to have installed in the next month or so. I am looking for information/opinions on what you think (or what set up you run) is the best throttle body for the set up? Would stock suffice? Am I better off going with a 52mm...or a 58mm? Any help is appreciated. I would like to optimize the new power the supperram will deliver so looking for most efficient set-up.

Thanks in advance...I look forward to chatting with you all soon!

If the rest of the motor is stock, the stock 48 will be fine. Defintiely don't go over a 52mm unless lots of mods, at least a 383, nitrous, or blower. Be wasting your money IMO.

yes, the rest of the motor is stock, just bolts on at this point (see sig below). what brand TB do you run on ur set-up? im thinking get a 52mm to throw on anyway for future mods...but am open to opinions. will the stock 48mm TB be ample to handle the output of the superram?

Or unless you know for a fact you will always be "modifying" your engine. I went from stock, to a 52, to a 58. I should have known better and went with the 58 from the start. Now I am considering an intake conversion to a single 4bbl style...It never ends.
----------
The BBK is a fair priced unit. IIRC, the 58mm is more $$ than the 52mm. If you plan on modding the 350, the 52mm should be fine.

I agree, Tom.

FWIW I'm running a BBK 58mm on my 383 and kinda wish I'd kept my 52 (sold it). I think the throttle tip in and normal driveability was better with the smaller TB.

RiggsLW81

iTrader: (4)

based on that..would going from a stock 48mm to the 58 mm effect my peformance in a negative way (since it would be too big for my current mods?) would you reccomend going to the 52mm and building up to the 58mm when necessary? Someone above mentioned loss of drivability with the 58mm..im looking for the best performance match to the stock motor with the TPI set up...i will not be modding the motor itself anytime soon. (save that for down the road)... and go with the BBK as best company to purchase from? let me know whatcha think...thanks!

brutalform

Looking at you original post, I would just keep the original one for now. If you plan any upgrades in the future, move up to the 58mm, and save yourself some money. Speed is an addiction, well, for me it is anyway.

You really do not have anything to worry about on a S/R with a stock TB on a stock engine. The S/R plenum does not have the lower walls cast into it as a stock TPI plenum does. IIRC, there was some info on here, that, if you put a 52mm T/B on a stock plenum, without removing the cast in walls, you would not pick up as much cfm, as you would, if you removed the cast walls, and retained the 48mm. The stock T/B would flow more, if you removed the casting walls, as a 52mm would with the walls still intact. Airflow is a funny thing like that.

ah...i gotcha. thanks for all the input. i think im going to hold off and stick with stock for now and not spend the 300 bones on the TB. since the thread is open though. who on the board likes BBK? Holley? Arizona Speed & Marine? Or Lingenfelter/Accel for BEST TB on the market? im curious to hear what you all have/think.....later!

brutalform

I'm using the BBK 58mm. I had used a TPIS 52mm previously. I had the problem of the TPS mounting holes stripping though. (common problem with stock style TB's). No problems with the BBK. I know of people using the Accel units with no problems.

@ZZKKER

iTrader: (1)

id say go with the big dude, but my opinion is biased and i have all the mods to support it, heads,cam intake (tb holes opened to match),headers, ect.

imo, the as&m is the best on the market right now, then the tpis 58mm a close second. the accel/lingenfelter is tied with holley for third, then the bbk units.

i like the accel/lingenfelter design because it is a huge block of billet aluminum.

enjoy

They polish up good too. The ownly downfall is the price tag. @ZZKKER is that the top plate yours came with?

@ZZKKER

iTrader: (1)

yea, the older accel/lingenfelter's have the plastic that looks cheap and tacky. i priced the top plate like yours has, but you can only get that piece in a kit they sell with a bunch of stuff i don't need nor want, and it was like $360 or something like that. to much in my opinion. i will just buy an aftermarket piece like MBA used to make, much cheaper.

i am going to polish mine when i finish the paint work and get all the bugs worked out of the motor. i polished everything else in the engine bay, but have to redo some stuff from messing the surface up from installing and removing to many times.

looks good by the way.

I have the Holley 52mm TB on my SuperRam...Very happy with it.

I'm running the BBK 52mm on my 355.
I don't seem to be having any problems.

You can buy just the throttle body plates themselves without buying any kind of expensive kit.

LT1 and L98 Chevrolet Billet Throttle Body Clean Air Cover: Lingenfelter Performance Engineering

That's what I did and put it ontop of my bbk 58mm throttle body...not because I am trying to fool anyone, but so that it matches the super ram.




Top the original poster though...I can't give you an opinion on the bbk one because I haven't gotten my engine into the car yet.

did you paint your superram yourself? looks great! what kiind of pain did you use??

also...ive just purchased a vortech supercharger off ebay that i will be putting on at the same time of my new supperram set up...with the addition of the vortech, im assumin i need to go to a 58mm TB...correct?

anyone have hp/torque estimates for my new setup? right now i have s stock L98 350, with edelbrock headers and a 3 inch flowmaster exhaust. im adding the supperram with high flow runners and a s1 vortech supercharger.

vernw

iTrader: (2)

"superram with high flow runners"?

There is only set of runners that I know of that work with the SuperRam intake - and that's SuperRam runners.

Did I miss something here?

4mul8r

I had it powdercoated. I'm not too sure on superchargers...but I don't know how important a tb is when air is being forced into the intake. I might take the money you were going to spend on the tb and use it on something that will give you more of a gain with the supercharger.

RiggsLW81

iTrader: (4)

vernw..my mistake, i did write high flow runners, what i ment to say was the runners the superram kit came with.

will i need a 58mm TB with the vortech charger? im unsure of hows its importance (the TB) would play out in relation to the addition of the supercharger.

I have had the lingenfleter 58mm throttle body on my 89 formula 350 for six months now,and have had no problems at all! Before the tires would not spin from a 20 MPH roll.But after the throttle body install.THEY WENT UP IN SMOKE! I say get the 58mm so you are ready for future mods.

pick up a used 52mm or 58mm off here or ebay then spend 300 on a SNOW performance alcohol injection kit with boost dependent adjustable turn on. that way you can run more boost without an aftercooler.

thats my

if I remeber the stock tb flows 650cfm.. could be wrong..

720 with an airfoil, per MIT flowbench.

I think the superram is a restriction at that point anyway. If you're gonna go with a horizontal draw through, I think MINIRAM is best bet. HSR doesn't quite flow enough, and the converted LT1 just ends up being fugly.

What I liked about my 4bbl TB was the progressive linkage. It was 1,000 CFM wide open, but only the front two plates moved for the first 1/4 throttle, making it easy to take off with a manual. That' gonna be a loss for sure when I goto a miniram on the vette.

Just my opinion, but if I was planning a blower down the line I'd probably try and stick with the factory TB for now and just plan on a 58mm when I added the blower. You probably don't need a 58mm right now with your mods and there's no point in having to buy multiples versions of them.

DeWynter

The SuperRam with Included TB will flow up to 1,000 CFM, I have a site with actual flow numbers somwhere, not sure where. Included TB is a 58mm.

RiggsLW81

iTrader: (4)

there is no TB included, it is for sale seperate from the kit which includes the plunum runners and intake.

i think im gonna do a 58mm TB--im gonna have my superram and the vortech installed all at once. im getting my work done at F-Body Motorsports 82-02 Camaro Parts, Z28 Parts, Camaro SS Parts, Firebird Parts, Trans AM Parts, GTA Parts, Iroc Parts, Formula Parts and Firehawk Parts - Camaro & Firebird Parts ... does anyone use the TPIS 58mm TB? im thinking about using that one, which is $500. i like lingfelters TB too, but that is $600 at the site. ive heards the TPIS unit comes with an airfoil already..true/false?

DeWynter

Sorry to miss post, but the sales packages must have changed as I got mine as a package fully polished with TB, computer (DFI) gen 7+, harness and software.

I'd stick with the BBK at $300 if it were me (and I did).

The BBk has the built in air foil (I think all the aftermarket pieces do)

What kinda price did you get on the whole SR unit? Where did you purchase? I am trying to locate one right now, can't find any used at the moment.

Here it is in all its glory, bit pricy but it sure gets the wow factor when you open the hood. The software is so awsome and the options for it are amazing. after the superram and computer I would go with the dual sync distributer and go to SFI. Only thing I didnt like about the setup is no MAF, only SD. Plus you can go to the coil over plug system of the LSX engines.

I have been running the LPE/Accel 58mm throttle body for about 10 years. The unit works well but I strongly feel that the front of the throttle body is a restriction because it is not radiused like all of the other aftermarket throttle bodies. If I were to buy one today, it would probably be the BBK.

Riggs - Knowing that you are supercharging your motor, I feel that placing a SuperRam on the motor is a mistake. Swapping the base manifold and a little cleanup on the plenum is all that is needed. I saw a guy with a basically stock looking TPI up in Wisconsin running 10's all day long. Trying to fill the large plenum will only bring down the boost. It's overkill until you start pushing some cubes.
