You should've said, "Do I LOOK like I have a vagina?"

My first car at 16 was a 99 GT Vert. Black with tan top and tan leather. I had full bolt ons minus headers and a chip (lol). Car made around 230 whp and 280 wrtq stock and about 260 whp with the mods I had. It is nothing compared to my 2013 at 380 whp and 360 wrtq stock and likely around 425 whp and 370 wrtq as it sits tuned on 93 with the Boss IM, Airaid CAI and 90 mm BBK throttle body (mostly good for throttle response)


These are going on the car soon. I cannot wait for the extra 30 whp and 35 wtrq throught the curve I should gain. Not bad for $799 shipped and a PITA install to come.

DerekDTP!

Damn my header/OR xpipe combo was like 1300+ but that was bought by the previous owner lmao, sounds great tho, the headers don't do much for power, maybe 4-5hp give or take, but I still think they're worth it, the xpipe is a big power Adder, with a JLT CAI, AR 1 7/8 LTs, Catless xpipe, 3" bullet exhaust and a AED tune I put down 434/405, I'd think your trq numbers would be higher

Terminator2

I am being conservative as I have not dynoed it yet but the Boss IM chops off about 15 ft/lbs from the normal torque spike at 4500 RPMs but it has much more area under the torque curve overall vs stock especially from 6500-7800 RPMs.
On the subject of longtubes I have spent so many hours doing research and have found differing opinions just like the Boss IM.
One guy on the forums went from catless 3 inch X pipe (lethal offroad X) to a JBA catless shorty 3" X pipe with JBA longtubes and he actually gained over 20 whp and 20 wrtq from just the longtubes!!!. He made another 20 whp on top of that going from 93 to E-85 on his car. The gains seem to depend a lot on the size of the primaries. The factory exhaust ports are 1 7/8" so anything smaller than that is a waste and it depends on tuning just like all the other mods. Many will tell you that larger primaries will sacrifice low end torque but on a high compression, high HP NA car that is BS. I have seen 8-10 whp and 10-15 wrtq differences even in the low end and midrange between using a 1 3/4" and a 1 7/8" (the 1 7/8"made more power across the board).

I've heard te LTs doing alot but I've heard more of them not, hard for me to say because I don't know my gains.. The car pretty much had everything on it, get some base line numbers and dyno numbers after the install

Terminator2

You had a buddy you raced with a 5.0 with the same basic mods as you minus LTs and he put down what ~415 whp which is about 20 whp less then you right?

DerekDTP!

All he had wa an OR Hpipe and a tune, it was a different tuner/different dyno, so catback exhaust, CAI and LTs are the difference

DerekDTP!

And I have an Xpipe rather than the H

Terminator2

Yeah who knows then unless he went on the same dyno as you with the same tune.

DerekDTP!

Yeah every car is different, my other buddy's 5.0 with the same tune, same Hpipe as the one that put down 415.. but also a catback(same as mine, 3" dynomax bullet) put down 421whp I believe, different dyno tho

415 and 421 could be because different dyno very small difference.

DerekDTP!

Yep, every dyno is different just like every car is different

Terminator2

Well after driving around for 2 days back on my stock throttle body I can honestly say there is definitely a throttle response and low end torque difference with the BBK 90mm even on a tuned car. The car feels like it wants to stall easier when I start off around 1200-1500 RPMs with the stock TB. I need to bite the bullet and port the Boss IM to 90 mm to match the TB because the reducer spacer does cause some air turbulance at some throttle openings (the air is forced to travel a non straight path because of the reduction right behind the throttle blade). It causes a whistle (restriction) at certain throttle openings and makes the car a bit sluggish when it is at those throttle openings. I believe with the Boss 302 IM inlet ported to 90 mm from 85 mm and the BBK 90 mm throttle body it will worth at least 10-12 whp (total between the porting the Boss IM and the 90 mm TB) over stock especially with the exhaust done on the car. I am already seeing over 723 CFM which is getting real close to the max flow of the stock throttle body assuming zero restriction.

Hey guys since this turned into a 5.0 thread ill post up the video a buddy of mine made this past weekend. I didn't turn off the traction control and esc so when shifting into fourth in the first and third run tc kicks in for a couple seconds and I drop back but I thought he was going to blow my doors off with his mods. I think the grille I have could have made a difference as well.

Terminator2

For your friend having an ORX, Tune and 3.73s vs your car stock with 3.31s (AB on an otherwise stock car is worth only a few HP at best) He should pull you easier IMHO. He should have at least 30 whp more than you and he has more aggressive gearing. Maybe his tune is very weak?

DerekDTP!

I agree^ who's it tuned by? Or maybe you got a factory freak lol

Red_SS/TC

I agree it has to be really weak. I think it's a 91 hybrid tune from Bama. I really thought he was going to put at least a bus length on me. I have also raced three other 5.0's (unknown mods) and pulled almost a car on all three but they were probably stock too. I should be getting my aed tune soon so hopefully ill be able to pull on him haha.

Terminator2

I will say this I believe the 2013 has a slightly more aggressive tune stock vs the 2011-2012. Typical gains seem to be 8-10 whp less on a tune on a 2013 vs a 2011 or 2012. They both end up around the same whp in the end though because the 2013 makes about 7-8 whp more than a 2011-2012 normally.

Term,
how does your car stack up against some of the cobalt cars you have tuned???

Terminator2

Less torque hit in the midrange and heavier car by 500-800 lbs (my base model comes in at 3480 lbs) but with just the Boss IM, Airaid CAI and 93 octane tune it is faster than any LNF on stock turbo even those on E-47 or E-85. 0-60 is 3.6 seconds logged with HP tuners. No 0-100 run yet but I would say it is in the 8.5-9 second range 0-100. Stock 60-100 was 4.89 seconds I have not logged it yet 60-100 since I modded it but it is likely in the 3.89 second 60-100 range currently and likely a 3.4 second 60-100 once I do the full exhaust.

damn, thats awesome. Cant wait to see it.
i gotta come see ya again when i get my stuff straight with my car and what i am doing

My longtubes and 3" catless X are on there way to me as we speak. I should have them by friday and hopefully have time to install them in the next couple weeks or so (I work a lot and the Mustang is my DD so I cannot have it down for more than a day) I went with the pypes 1 3/4" to 1 7/8" stepped headers over the JBA 1 7/8" headers. I got them for $800 shipped. Pypes claims 48 whp and 20 wrtq with the headers an X pipe but I believe that was with a mild tune on the car as well but either way I will be happy with even a 25-30 whp gain as my car is already traction limited in 1st and 2nd (spun for a second or so shifting into 3rd last night not just a chirp like sometimes) I could not imagine this car with 3.73s or 4.10s like some have.

Still thinking of e85? Just saw a post of a car on svtp with similar mods, LTs, xpipe, CAI, 47lb injectors, e85 tune- 447whp/417wtq

Terminator2

Yep if the station down the road from work ever gets it in again I will do an E-47 blend on stock injectors, etc. No other E-85 stations within 65 miles each way of me.
