A Nice Discussion On The Lx Forums About The New 90mm Throttle Body By Lmspeed!!!

just wanted to post and let people know that i have posted on the lx forums about a 90mm throttle body that i had put on my car today. got very good results and the throttle body has about 100 miles on it so far and is only getting stronger.

i spent most of the day today putting on the throttle body that ED at lmspeed has for sale. we did a baseline dyno before putting the throttle body on and then after. we saw good gains. ~5 hp all across the board and ~8 tq across the board. we also stopped the dyno short at about 5200 rpms and we were still climbing with both hp and tq numbers. i have about 100 miles on the throttle body currently.

i have noticed a little better throttle response, a different engine tone ( a bit more throaty sound from the engine/mopar cai), and more noticably a substantial gain in the 2k to 3k rmp range. the longer this is on the car the better it will get.

the throttle body was a plug and play. no tuning was done to achieve these numbers. no other modifications were made. as ED stated above it will make more power if it was port matched to the manifold and if the manifold was his stage 2 (this is the next step). if anybody has any questions regarding this set up please feel free to pm me or just ask. ED has come up with an awesome product for our cars that everyone can afford. NICE WORK ED AND ALL AT LMSPEED!!

This is what vendors are saying....helps to tune it. Who is ED though? Is he a vendor at LXF then? Never really heard of them.

 

yes it would help to tune the car in order to maximize the gains. however you can just plug and play if you like. a/f are in the safe range without tuning.

yes ED is the owner of LMspeed, they are vendors on the lx forums. they are very new. they have been gm tuners for over 15+ years.

ED is getting into the hemi market with a bang. he has been very quitely making many parts for our cars and is coming to market with them all very soon. he has an awesome manifold+throttle body+air intake combo

 

i believe $699 if you have the stage II manifold done. if not it would be $45 more for the adapter flange necessary to go from the stock manifold to the 90mm body. many people were asking for a plug and play so that is what the flange is for.

 

Is this the Arrington 90mm TB that PPP and others are selling or is it somthing different?

 

it is something completely different

 

Very cool..finally some competitive products with affordability built in.

 

Competition is a good thing, however... GSM/PPP (or someone else?!?!) is claiming like 20 rwhp/20rwtq gains over stock TB... big difference between 5hp and 20hp.

 

i did not see the adapter at their site. do they have them or is it someone Else's?

 

I read the thread on LX...some...ummm..interesting debate going on lolopcorn:

Looks like this TB is a modified GM unit.

 

i cannot speak about anybody elses gains or claims. however the owner of LMspeed dynoed my car for me free of charge as it came in the door and as it left with the 90mm throttle body for me. i was impressed enough with the dyno because it was still making power at 5200 rpms and my max power is made at 6275 rpms according to the mustange dyno i had done the day before. i am going to have the are dynoed again in about a month in order to check gains. also it gives the computer time to learn the mod. also those 20 hp and tq gains could have been with a tune or some fuel added. this was plug and play nothing else.

 

Roger that!

 

the adapter is currently being made. as usual chrysler is being difficult they are looking for a male end of a six pin connector in order to make the harness completely plug and play.

and yes it is a gm unit that has been modified in order to work in our cars. why re-invent the wheel ("throttle body") when gm has made it perfect already. a throttle body is a throttle body to an extent. i am sure they did this in order to keep cost down for the mopar guys like me. otherwise they would have to have one made that did the same thing for twice as much. it in no way shape or form says gm on it rest assured.

i am loving mine and i have only had it for 100 miles or so. i will post daily as to the results.

 

5 hp gain... you should definately get a tune get the power. The dyno runs on the Arrington 90mm TB was a lot higher....like 20 something on a stock engine, but it was predator tuned.

 

i know everybody wants me to show a 20 hp gain but it just didn't happen. i have been around cars for many many years and have owned a couple of modified z28's and i will tell you guys something. these cars are very difficult to dyno due to the extensive management and computer controls associated with them. the dyno results alone were not the reasons i was buying it.

this unit gives me better throttle response, and a throatier sound to my engine and also nets at minimum 5hp and 8tq across the board. and this is with no tune or adaptive learning. i believe the longer it is on the car the more power it will make. hope this helps guys.

 

please remember that this had nothing done to it. just plugged it and played it. i am going to get the car re-tuned with it very soon. also give the car the chance to learn the mod. all cars learn. remember the first few days with your new cai. hell i remember mine and my car seemed like it didn't want to move at first. then it came around.

 

Very interesting. Competition is good. Looks like a GM TB off of an LS2 or LS7.

 

Do you have a Predator?
Check out post #47 here and you can see how much more power you may be loosing without PCM tuning. PPP got 47HP with CAI and Predator tune. In post #66 he says the TB was worth 18HP out of that 47HP gain.

And remember.....these numbers were on a stock manifold with an adapter, not a ported one like LMSpeeds. Did you use this intake or an adapter?
Remember not all the PCM settings are adaptive. The fuel maps will need some adjustment and the more fuel you can give a 6.1L the more power it can make (to a point of course). All of our cars that have been to a dyno needed positive fuel adjustments to show power, which we were able to do with the Predator.

 

it was installed on my stock manifold using the flange.

 

Because it is a GM TB ...
