1979-1995 Mustang Trickflow Twisted Wedge 11R Cylinder Heads - Dyno

53cc Heads: lmr.com/item/TFS-52515301CK1/...
56cc Heads: lmr.com/item/TFS-52515601CK1/...
These highly potent twisted wedge heads have been modified with 3D modeling to feature new, restructured 11 degree intake and 13 degree exhaust valve angles to provide more airflow and performance! This set features the Street Ported runners which are a great entry-level CNC ported head to gain significant improvements over the factory heads. They are available with either a 53cc or 56cc combustion chamber. These heads are for OFF-ROAD use only and will not pass emissions testing.

I used these with a ford B cam on a 331 stroker years ago, trickflow intake, bbq shorty headers, and it pushed out 390hp at rear wheels at the dyno shop, I miss my old fox body

[@evilinside5984]

The prob. is different dynos, are calibrated diff.= will give diff. results. Im sure your combo ran well, and you sound like you were happy with it? But the engine in this video, has way better flowing 11R cyl. heads ( that werent available back in the day), with the smallest cc chamber ever offered by Tfs, for stock 302s= more compression ( 11 to 1 comp. In this 331)= more power, with a more powerful cam= Tfs stage 2, specs.= (int. Dur. @ .050- 224°, Lift .542), (exh. Dur. @ .050- 232°, Lift .562), Lobe sep. 112°, vs B cam specs.= (int. Dur. @ .050- 224°, Lift .480), (exh. Dur. @ .050- 224°, Lift .480). I would think this 331, in this video, has approx. 40 to 45Hp more or so, then your combo? Dyno shops used to setup there printouts to show the customers, estimated Flywheel Hp., and Tq., making the customer think the readout/printouts were chassis dyno results. If they did that, your 390Hp would make more sense, as the Tfs 11R heads, with 53cc, and stage 2 cam, made 432Hp on trick flows engine dyno, = +42Hp more than yours. Again not hating, just trying to put your power #s into perspective, vs these power #s.

[@scottmcclure8933]

I am so glad I live in a Georgia County that has no emissions testing....

[@msk3905]

Great gains thats roughly what i made (same HP but a few less TQ) with my 331ci back in 90s with TFS twisted wedge heads, Shorty headers are holding that setup back.

[@dgambrel9241]

I went from 6.43s in the 1/8 with shortys to 6.42s with long tubes and then 6.41 with a victor JR. 351, flat tops, .600ish cam, dart heads, 750 Holley, 125 sniper jets, th400, 4000 stall and 4.56s. Shorty’s aren’t that bad. Had a similar set up on a 3rd gen firebird just a gm version. 355 flats, victor jr, 4.56 gear 125 same trans and 4.56 gear after some weight removal ran 6.50s with shortys. Not all shortys are created equal

Big difference between those two cylinder heads, particularly when comparing to the 170cc's. The 190 11R's move a LOT of air.

[@megantripp9520]

just do a 351w swap! its the best investment i ever made..you immediately gain an extra 50 c.i. that with minor work and $ bolts directly in and if you so choose a 351w can be stroked to a 408, 418, 427 stump pulling cubic inches in a stock block and still be reliable...theres no replacement for displacement.

So the results were: "Built 331" with basic bolt ons, shorty headers, aftermarket H/C/I: 363rwhp/376rwtq or 1.10rwhp/1.14rwtq per ci. For comparison, the dyno results on my 2006 GT were: Stock 281 3V with basic bolt ons, stock exhaust manifolds, stock H/C/I: 310rwhp/328rwtq or 1.10rwhp/1.17rwtq per ci. Basically shows just how efficient the stock 3V H/C/I are right out of the box.

[@afri1414]

I wish they would have given us more info on that car. I made 320 hp & 332 tq with a stock 302 shortblock, 11R 190 heads, an Ed Curtis cam and Holley SM2 on 93 octane through a stock AOD and converter.

Basically, 3V's have proven to be the most UNimpressive mod motor to date...

[@DJDinaggio]

@@02autogt Totally disagree with you there mate. I think that title goes to the '98 & earlier 2V engines, though they do have longevity in their favour. The 3V is also very reliable but you have to keep on top of the oil changes, and use a high quality synthetic blend or full synthetic to avoid problems with the VCT system.

[@dennisrobinson8008]

3V certainly has more potential than the 2V's. The heads can flow similar to gen 2 Coyotes with porting on the intake side. @@DJDinaggio

more torque than horsepower needs a bigger 11R head like 195 comp port small cc combust chamber

Which intake should they have run. I'm so used to seeing LS numbers. A good built LS1 ( 346 ci ) make 400-460rwhp with 400-420rwtq. It'll have stock bottom and from stock to 300cfm@.500" lift type of aftermarket head, cam, exhaust, possibly intake ( ls6 or fast ). A good built LS3 will make 450-550rwhp and 430-465rwtq. I want to see 331 and 347 fords making 420-550 rwhp and torque over 400 rwtq, showing good efficiency in the combination. @@evilinside5984

tukamoton1312 he mentioned some upgrades before watch the video again

[@say11911]

Exactly! How many "stock" applications run 110 leaded race fuel? None. They are designed to run pump gas, which tells me this engine in order to use 110 octane is running a compression ratio at/above 12:1 and not "roughly 11:1". Even with aluminum heads, efi with knock sensors and custom maps I don't recommend going above 11.8:1 (N/A) on pump gas or a dynamic compression above 8.4:1. Unless you are planning on running E-85 (the 85% ethanol : 15% gas, octane rating of 100-105). Ethanol responds like race fuel, it burns lower temps and slower - which requires high compression to harness the energy. This test is misleading to guys building a streetable car....On the street you use what is at the pump, there were no cam specs given with the swap, no rocker info, no dyno barometric pressure or corrections given. In essence this test didn't have the pertinent info for consumers to make an informed choice.

[@eriv4735]

+Say11911..I’m not sure if you know how to read or are deaf but he clearly states the car is 11:1 comp which is pump friendly idk where the hell you are getting 110 from lmfao..regardless he clearly states that this mod is for off road use and they are testing a TRACK car which if one had sense would assume this is race use lmfao..he also clearly tells you the make and model of each part if you are too lazy to google specs well that is on you..barometric pressure?..lmfao now your just being an ass
