Absolute S2 Dyno Numbers (SAE) w/ Tuning
Re: Absolute S2 Dyno Numbers (SAE) w/ Tuning Yes.. they were interested in the results as well.
I'm looking to add some additional cold air from both the front and from below the car.

Re: Absolute S2 Dyno Numbers (SAE) w/ Tuning JS brings up a point I did not even think of the gear loss.So between the gear,the Cats,and the mid length as opposed to long tubes how much would you think was left on the table?Was there a cut out?If not there a few more.My Dads car pulled just over 400 with an unlocked Yank 4400 with 224/224 Thunder cam and stage 2 Absolute Speed heads.I have trapped 121.4mph on a 1.51 60' et was 11.04(talk about bangin on the 10 sec door).We plan a redyno soon with the converter locked and should see some hp recovered.

I do agree though, dynoes are a tuning device, nothing more nothing less. The numbers look good to me, certainly the car is very capable of 11.8s @ 119 MPH on a BFG.

Re: Absolute S2 Dyno Numbers (SAE) w/ Tuning MRB,
The numbers look good. If you had no cats and 3.42s you would be closer to 410. As it sits now, you are street legal and will have a nasty highway runner....

Re: Absolute S2 Dyno Numbers (SAE) w/ Tuning tuning is not always about big power numbers
its just thats the first thing people
look at and remark about
we do not tune cars to put up a big number and send them on their way
we like to find out what they are looking for in a tune up and how they are going to drive the car
Our big thing is drivable with correct air fuel
and a safe and happy timing curve
half the cars we see at the track or on the street
run poorly,start hard,stall
we try first to make the car run well,then make power but safely

Re: Absolute S2 Dyno Numbers (SAE) w/ Tuning Different dynos read differently. His numbers may even differ on the same dyno at a later date.
Besides, actual performance data tells more than dyno numbers anyway. Hypothetically, if I dyno'd ~370 rwhp but was running 120mph in the 1/4, I wouldn't be too worried about it. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: Absolute S2 Dyno Numbers (SAE) w/ Tuning Ok, im gonna stop comparing now...
Yes, looks good and i was not comparing autos to manuals and MTI to absolute heads.It Does have a real nice solid dyno curve, through.. Should run good.

The guys at Eastside were interested, and so was I.. so down went the hood. I'm going to devise a way you adapt the SLP CAI and add some ventilation in the front of the stock formula hood to add to the amount of cool air available. After all, I learned right here on LS1Tech that the LS1 was nothing more than an elaborate air pump.

Re: Absolute S2 Dyno Numbers (SAE) w/ Tuning did you also dyno with the hood open so that you can compare closed hood vs. open hood?
i think closed hood reduces hp by about 5 hp on a mostly stock LS1. i wonder what it costs hp on a H/C LS1.

The MAC's are usually equal to LT's on peak hp. In some cases a mid length header like the MAC or Bassani can actually make better peak hp than a LT.

Do you have any dyno figures on the bassinis to actually argue that claim? I have sein some dynos that have shown hardly any gain with the bassini, but not enough to justify. Please share if you do... Thanks.

Re: Absolute S2 Dyno Numbers (SAE) w/ Tuning Blazin,
I should have been more specific. I've seen dyno results on MAC's vs SLP LT's on the same car. I've not seen any results on the Bassani.
Under 4500rpm the SLP make more torque ~10 and a few more hp than the MAC's.
Over 4500 the MAC's make 10-12rwhp more than the SLP's.
I don't have a copy of the graphs but that was what I saw.

Re: Absolute S2 Dyno Numbers (SAE) w/ Tuning agreed with the macs blackbird, thats said and true... But the bassini's are new to me and havent heard great stuff by them, but hey, its only the internet.
