Ok I am really thinking about getting a non cooled whipple and getting the intercooler later on down the road. K this is my question. Say you have two mustangs... one with a non cooled whipple running the tune they come with putting down idk..405hp, and another mustang with the cooler and the tune that comes with that kit putting down 470hp. Would the intake temps be about the same being as the cooled kit is putting down more power.. just curious..sorry if this sounds complicated...

 

I'm not sure your question is about temperatures. You can run higher boost levels and not have detonation with an intercooler. Thus, the cooled version can produce more power. You can also do a methanol injection system to further boost without detonation. The key is to build power without detonation. You can run a 93 tune with 87 octane and have detonation kill a motor. What you need to do is make sure you have detonation under control no matter what your setup. Get a local tuner to walk you through your potential mods. Our local guy here is great and he always gives you options and informs about gradual steps to fit your budget.

 

Thank's, I know exactlly what I need and want but I was just a little curious about the temps between a s/c with a cooler and without a cooler. I know you can run higher boost levels with an intercooler and have lower temps and make more "safer hp" with an intercooler but would the temps be lower with the higher hp levels of a cooled s/c versus a non cooled sc running less hp?

 

Well, only way to know for sure it for people to post what IAT's they have seen while datalogging.

Mine is intercooled---and just today I datalogged IAT's in the 142 range with a high of 150. Some things you need to know, however---

1) IAT was taken from AFTER the supercharger in the intake manifold
2) This was at 75 mph
3) Temp was roughly 92-94 degrees (it was hot today)
4) This is at 16psi.

Now, have someone who has a non-intercooled kit post up there typical IAT's, hopefully someone out there has datalogged this with similiar conditions, and with the IAT gauge sending unit AFTER the supercharger in the intake manifold. Before the blower, the IAT will pretty much just be ambient air temp.

 

Adam,
I'm not going to get into internal temps because I don't know the answer to your question. I just wanted to comment on the rwhp of the non-intercooled Whipple. I have the non-intercooled Whipple. It was installed and with the FRPP tune and the 6lb pulley it put down 324 rwhp. With Doug's tune and an 8lb pulley it went up to 344 rwhp. I too want to get an intercooler and 10lb pulley down the road so I can reach and hopefully exceed 400 rwhp. I know this was sorta off topic............just FYI.

 

Thank's guy's, I appreciate the help...oklacop, 324 rwhp isn't too much. I thought it would be more than that....i'm not trying to knock u because I want that system but I thought it put down more hp than that

 

Thats what the non-int. kit puts down with the FRPP tune. After Doug's tune I'm at 344 rwhp...........that was my last run on a hot day with an even hotter engine bay. We didn't have time for another run, but we estimated that had we run it again after letting it cool off it would have been around 350-360 rwhp. This is why I want an intercooler and a 10lb pulley.

 

324 is really bad, especially with longtube headers. Just the headers, CAI and tune should put you around 300 so the Whipple in out of the box form was worth less than 25hp. Ouch. Does it feel much faster? Do you actually have a boost gauge on it to know if you're making proper boost? I live a few miles away from Whipple and plan on them doing the work but I better see a lot more than that. They claim 405 rwhp with their standard low boost kit.

 

Whipple claims 415hp at 6 psi of boost with their low output system. I don't beleive that's rwhp though.

 

I'm not an expert by any means, but I believe the answer to the original question is this:
In theory, the inlet temp on the intercooled version is cooler and that's why they can run more boost and get more horsepower. Hotter inlet temps increase the likelyhood of detonation. That's how I understand it.

 

You are a smart man Chad!!!!!!!! And you understand correctly! and welcome to the forum!!

Even while running 70 more hp?

 

Hi Adam,
Detonation can occur even in N/A engines that are not tuned correctly. All superchargers and turbochargers heat the intake air charge due to the compression of the air. The higher the boost levels the more heat created and the more chance for detonation to occur. Superchargers will create about 15 hp/lb of boost. So a 6lb kit is worth about 75 hp. The Ford tune that comes with the Whipple is not aggressive at all. But it is safe for all of the coniditions across the country. There is more hp available with a more aggressive tune but at the risk of increasing the chance for detonation. So to answer your question "yes" it is possible to only add 70 hp and increase the chance for detonation. But it always comes down to the same thing. Running a good tune and proper octane gas will reduce the chance of detonation. Adding the intercooler just allows you to run more boost and make more power before that threshold is crossed of creating to much heat in the incoming air.

nice Scott...thank's, that's what I needed

 

It's interesting that Oklacop only gained 20 hp with a 2 psi increase in boost. I would think he'd have gotten more than that even without Doug's tune.

 

All I can say is the FRPP tune is weak! I do have a boost guage and w/ the 6lb pulley it showed 6 lbs and with the 8lb pulley it's showing 8lbs. Again, after tuning our last run was with a very hot engine and showed 344 rwhp. Doug and the Ford tech both thought if the engine had time to cool it would be putting down more like 350-360. I won't know that until I have it dynoed again when it's cool. My car is an auto too. Don't remember if I posted that eatlier, but that is another reason for the lower numbers. I guarantee Ford Racing and Whipple are advertising their hp gains at the flywheel........not true rwhp.

If you read the Project Milf articles in MM&FF it will give you some insight to the Whipple and what gains they made. If I remember correctly, My car is pretty much right in line with their test car in the articles.
