Who has AT Power Throttle Bodies

[coffs_vtr]

as the title says, who has got some of these fitted? looking at getting some, also what management are they using, and is there much of a gain? rolling road results anyone?

cheers

[raunchz]

People are running these with Predator mostly (AndySaxoK), although Toad is running his with emerald.

[Ryan]

gain will be dependant on the cam choice with them ;)

They can be used with any decent standalone (or bodged OE ecu map)

[boabVTR]

im going to be running throttle bodies but im getting mine off a suzuki gsxr 600. and will be running an omex ecu

iv got newman ph3's to go in aswell mate

[coffs_vtr]

yeah iv been looking at the predator seems a good choice for the price, anybody got any figures yet or no?

[raunchz]

AndysaxoK got 157@fly on some strict rollers with ATPower, Ph3's and Predator.

Could easily go over 160 I'd say with a small amount of time on the dyno, and a camtiming tweak

Dont get hung up on figures, rollers will read differently.

The bodies will give much better throttle response and generally better midrange.

If you are talking about northampton their new rollers seem to be pretty much spot on tbh.

[AndySAXO]

yer i am using them with PH3 newman cams, and also predator, the map was spot on, but yer with some time spend on a dyno with cam timing tweeks i think i could hit the 160 mark, but they are very good peice of kit,

i few issue with them though, they are angle too low so a filter can be alittle be hard to fit, but can get a filter on them, look at my thread for pictures, also the brass throttle cable end need to be made smaller!!!

me and andy had to file it down abit to fit, also GMC fitting kit, you can use all the screw as cant get them in all the holes!!

yep that was on saturday, they told me that they had a TB 106 the other week that only made 145 on throttle bodies,

and a twingo sport that are 131 bhp standard made 131 on there roller the same day!!

also yep figures are good, but it moe important thing like wat ryan said, it make it drive alot smoother aswell!!

im not too bothered mate, just wanted a rough idea to see if it worth spending the money:)

[coffs_vtr]

andy- thanks for the advice mate, il have a look into it andy from datashift looks like he knows what hes doing and gets good feedback:)

customer service wise andy is a good guy to deal with. Hes a genuine enthusiast.

[Thecherry0121]

Andy at datashift is a sound guy knows his stuff :) Im runnig the at power boddies and the pred and for the money im very happy tbh :) Youd be suprised what youll keep up with i know i am.

[Phsyco_Paff]

So to get this set up you need

predator ecu
the bodie's
cams and pullys
4 branch
mushroom filter
Remap

= 2000+

And then you make 160 Bhp on the rollers seems a lot to make 30-40 bhp tbh.

[AndySAXO]

andy is a sound guy, a very nice bloke :y:

his maps are very good too!!

also it not just the peak power you look at, it totally differnet to drive!

Also the noise too if you hear the noise then you would have a differnet option on it :P

andy

seen a 106 gti with bodie,s was a very impressive noise tbh suppose you do get that free :P

power to weight ratio is good thoe :y:

[luthor1]

Don't bother with the pulleys, the standard ones are adjustable so quite a bit of money to save there.

Predator £550
Fitting and mapping £75
Bodies £915 (I think from GMC)
Manifold £150 for Janspeed I think
AT Power Air filter - £120?? Andosaxouk will correct me...

Fitting the cams and bodies I'll do for £240

You're increasing the normal engine by 33% without forced induction, that's extremely good! Also, because it weighs nothing, it makes a big difference. Also you'll pull an extra 600rpm which takes it into another league through the gears too!

Kind regards

Andy

[AndySAXO]

the at power air filter with backing plate and cut to fit the bodies was 106 quid posted.

andy

[Ste]

Highest power ive seen with the AT bodies is 182bhp;

Newman PH4
High Comp Pistons
172 Injectors
Standard Remapped ECU
Mani + full system

The RR printout shows the pull to be very very smooth and tbh one of the nicest power curves ive seen!

[raunchz]

Or Toads at 190+ with oooodles of torque

[jpsaxo]

wasnt toads 185ish? im sure he will correct us. But either way they seem to be making good gains, just the induction angle / filtration seems to be a big issue with them, which you'll want if your keeping the engine healthy!

[Ste]

Nice, havn't checked Toads thread out in a while.

The actual max BHP figure is really a red herring. It's also responsible for the reason why so many people say "It's not how much power it makes, it's how it drives on the road." This statement is true, but if you read into the power figure from a dyno run in more detail, it actually tells you a lot more things which ARE very relevant.

It's not much use having a high max BHP figure with no torque to back it up. All this means is that the engine is reving highly. You want power / torque where you're actually going to use it.

Andy's result is an interesting one. It produced a max of 157bhp, and max torque of 111lb/ft. The torque figure is only 4lb/ft greater than a standard engine setup. The reason the max BHP figure is high is because the torque stayed very constant high up the RPM range; The fact that the torque stayed very level high up the RPM range is a good thing, but it looks like the downside is the fact that the actual amount is not very much. Therefore, Andy is only going to benifit from driving at around 6000rpm+

Pug1Off has experiemented with a number of cars running 708s and PH3's and they've pretty much proven that fitting iTBs to the 708s only gives about 5bhp extra. PH3's do a little better, but not by a lot. As Ryan has stated numerous times, the real benifit of iTBs is the ability to run wilder camshafts.

[Ryan]

Pug1offs results though dont show the improvements throughout the rev range though dave, which is where there will still be benifits.

its not just about peak power, bodies will improve the overall drivability of the car.

[AndySAXO]

yer toad, i know my torque is low but is flat i want to get that higher mine still need the final tweeks,

but it ok for now, will be using nms to get the final tweek done next year,

but for a road map it not to bad.

also that other at power bodies engine where was that mapped?

andy

[Ryan]

the other engine sounds like rickyps which will be a wayne schoefield map.

[AndySAXO]

o the chipwizard dyno, but that a different story!

anyway i see what toad said about mine, i think that more to do with the cam timing, but should be able to get that up more once i get back to NMS to the final tweeks,

but back onto the subject about AT powers,

they seem to proforming well to me, seem to flow well, but one down side is the angle they are at really are bit low!!

you can get a filter on them but it is tight,

andy

[coffs_vtr]

thanks for all the input guys, so i take it i will be able to fit wilder cams like a ph4, that way i will get more power than my ph3's which i already have?

[raunchz]

:y: simples but will need hi comp pistons to get the best out them re: cam timing

[Ryan]

wilder cams isnt just a bolt on though, usually need high comps (valve cut outs in pistons) new better valve springs etc...

Then wilder still requires solid lifters etc....

[Ryan]

lol the 155bhp 708/ph3 ones ;)

[coffs_vtr]

ah ok guys thanks, think il stick with the ph3's :) and think im going to go for the predator now that andy has got them sorted

[AndySAXO]

lol the 155bhp 708/ph3 ones ;)

lol yep they are the ones,

also yer also with Ph4 cams MOT will be alot harder to get though atleast with PH3 /708's can get thoguh MOT with a CAT and a few tweeks.

andy

[raunchz]

andy

lol,I tried to get through an MOT with a standard exhaust, BP285s and TBs and adjusted the idle so it was spot on 14.7:1 - still no where near emissions.

gave it to the MOT place to sort out the emissions for MOT ;)

[Ryan]

andy

MOT I cant wait for mine with the 803s once its running again lol!

[raunchz]

lol - could be tricky !

[Ryan]

lol - could be tricky !

Expensive sports cat and a friendly tester is the way *i have the cat sorted lol*

[AndySAXO]

i find sport cat are not as good as the standard ones, for the MOT the standard one seem to bring it down more than a sport cat,

andy

[Ryan]

andy

This was a £600 sports cat and seems to have done the job for previous owners, Id like to see someone trying to fit a standard cat into my set up lol

[Drago]

i find sport cat are not as good as the standard ones, for the MOT the standard one seem to bring it down more than a sport cat,
andy

That will be because the standard cat contains more cells effectively "cleaning" the gases more before they exit the system.

[AndySAXO]

yer will ryan if you can fit then that you cant, but i know standard cat seem to wokr better,

I'm aware of the benifits... What do you mean by theirs don't show them? Point is, people chasing figures will be disappointed.

Yes, it should improve driveability, but it's specific to the application, as we've just seen with Andy's...

You stated that their results just show a few bhp increase. When bodies are not about just improving peak power. Midrange drivability is one of the key factors when it comes to them.

Most people serious about tuning are generally aware that tbs dont give huge gains its just the noobs who think wanging on some cheap crappy bike bodies will give them 220bhp lol.

[Toad]

I did state that. I was referring specifically to that though. Obviously just a bit of confusion...
